++ASoC currently supports the three main Digital Audio Interfaces (DAI) found on
++SoC controllers and portable audio CODECS today, namely AC97, I2S and PCM.
++
++
++AC97
++====
++
++ AC97 is a five wire interface commonly found on many PC sound cards. It is
++now also popular in many portable devices. This DAI has a reset line and time
++multiplexes its data on its SDATA_OUT (playback) and SDATA_IN (capture) lines.
++The bit clock (BCLK) is always driven by the CODEC (usually 12.288MHz) and the
++frame (FRAME) (usually 48kHz) is always driven by the controller. Each AC97
++frame is 21uS long and is divided into 13 time slots.
++
++The AC97 specification can be found at :-
++http://www.intel.com/design/chipsets/audio/ac97_r23.pdf
++
++
++I2S
++===
++
++ I2S is a common 4 wire DAI used in HiFi, STB and portable devices. The Tx and
++Rx lines are used for audio transmision, whilst the bit clock (BCLK) and
++left/right clock (LRC) synchronise the link. I2S is flexible in that either the
++controller or CODEC can drive (master) the BCLK and LRC clock lines. Bit clock
++usually varies depending on the sample rate and the master system clock
++(SYSCLK). LRCLK is the same as the sample rate. A few devices support separate
++ADC and DAC LRCLK's, this allows for similtanious capture and playback at
++different sample rates.
++
++I2S has several different operating modes:-
++
++ o I2S - MSB is transmitted on the falling edge of the first BCLK after LRC
++ transition.
++
++ o Left Justified - MSB is transmitted on transition of LRC.
++
++ o Right Justified - MSB is transmitted sample size BCLK's before LRC
++ transition.
++
++PCM
++===
++
++PCM is another 4 wire interface, very similar to I2S, that can support a more
++flexible protocol. It has bit clock (BCLK) and sync (SYNC) lines that are used
++to synchronise the link whilst the Tx and Rx lines are used to transmit and
++receive the audio data. Bit clock usually varies depending on sample rate
++whilst sync runs at the sample rate. PCM also supports Time Division
++Multiplexing (TDM) in that several devices can use the bus similtaniuosly (This
++is sometimes referred to as network mode).
++
++Common PCM operating modes:-
++
++ o Mode A - MSB is transmitted on falling edge of first BCLK after FRAME/SYNC.
++
++ o Mode B - MSB is transmitted on rising edge of FRAME/SYNC.
++
++
++ASoC DAI Configuration
++======================
++
++Every CODEC DAI and SoC DAI must have their capabilities defined in order to
++be configured together at runtime when the audio and clocking parameters are
++known. This is achieved by creating an array of struct snd_soc_hw_mode in the
++the CODEC and SoC interface drivers. Each element in the array describes a DAI
++mode and each mode is usually based upon the DAI system clock to sample rate
++ratio (FS).
++
++i.e. 48k sample rate @ 256 FS = sytem clock of 12.288 MHz
++ 48000 * 256 = 12288000
++
++The CPU and Codec DAI modes are then ANDed together at runtime to determine the
++rutime DAI configuration for both the Codec and CPU.
++
++When creating a new codec or SoC DAI it's probably best to start of with a few
++sample rates first and then test your interface.
++
++struct snd_soc_dai_mode is defined (in soc.h) as:-
++
++/* SoC DAI mode */
++struct snd_soc_dai_mode {
++ u16 fmt; /* SND_SOC_DAIFMT_* */
++ u16 tdm; /* SND_SOC_HWTDM_* */
++ u64 pcmfmt; /* SNDRV_PCM_FMTBIT_* */
++ u16 pcmrate; /* SND_SOC_HWRATE_* */
++ u16 pcmdir:2; /* SND_SOC_HWDIR_* */
++ u16 flags:8; /* hw flags */
++ u16 fs; /* mclk to rate divider */
++ u64 bfs; /* mclk to bclk dividers */
++ unsigned long priv; /* private mode data */
++};
++
++fmt:
++----
++This field defines the DAI mode hardware format (e.g. I2S settings) and
++supports the following settings:-
++
++ 1) hardware DAI formats
++
++#define SND_SOC_DAIFMT_I2S (1 << 0) /* I2S mode */
++#define SND_SOC_DAIFMT_RIGHT_J (1 << 1) /* Right justified mode */
++#define SND_SOC_DAIFMT_LEFT_J (1 << 2) /* Left Justified mode */
++#define SND_SOC_DAIFMT_DSP_A (1 << 3) /* L data msb after FRM */
++#define SND_SOC_DAIFMT_DSP_B (1 << 4) /* L data msb during FRM */
++#define SND_SOC_DAIFMT_AC97 (1 << 5) /* AC97 */
++
++ 2) hw DAI signal inversions
++
++#define SND_SOC_DAIFMT_NB_NF (1 << 8) /* normal bit clock + frame */
++#define SND_SOC_DAIFMT_NB_IF (1 << 9) /* normal bclk + inv frm */
++#define SND_SOC_DAIFMT_IB_NF (1 << 10) /* invert bclk + nor frm */
++#define SND_SOC_DAIFMT_IB_IF (1 << 11) /* invert bclk + frm */
++
++ 3) hw clock masters
++ This is wrt the codec, the inverse is true for the interface
++ i.e. if the codec is clk and frm master then the interface is
++ clk and frame slave.
++
++#define SND_SOC_DAIFMT_CBM_CFM (1 << 12) /* codec clk & frm master */
++#define SND_SOC_DAIFMT_CBS_CFM (1 << 13) /* codec clk slave & frm master */
++#define SND_SOC_DAIFMT_CBM_CFS (1 << 14) /* codec clk master & frame slave */
++#define SND_SOC_DAIFMT_CBS_CFS (1 << 15) /* codec clk & frm slave */
++
++At least one option from each section must be selected. Multiple selections are
++also supported e.g.
++
++ .fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_LEFT_J | SND_SOC_DAIFMT_RIGHT_J | \
++ SND_SOC_DAIFMT_NB_NF | SND_SOC_DAIFMT_NB_IF | SND_SOC_DAIFMT_IB_NF | \
++ SND_SOC_DAIFMT_IB_IF
++
++
++tdm:
++------
++This field defines the Time Division Multiplexing left and right word
++positions for the DAI mode if applicable. Set to SND_SOC_DAITDM_LRDW(0,0) for
++no TDM.
++
++
++pcmfmt:
++---------
++The hardware PCM format. This describes the PCM formats supported by the DAI
++mode e.g.
++
++ .pcmfmt = SNDRV_PCM_FORMAT_S16_LE | SNDRV_PCM_FORMAT_S20_3LE | \
++ SNDRV_PCM_FORMAT_S24_3LE
++
++pcmrate:
++----------
++The PCM sample rates supported by the DAI mode. e.g.
++
++ .pcmrate = SNDRV_PCM_RATE_8000 | SNDRV_PCM_RATE_11025 | SNDRV_PCM_RATE_16000 | \
++ SNDRV_PCM_RATE_22050 | SNDRV_PCM_RATE_32000 | SNDRV_PCM_RATE_44100 | \
++ SNDRV_PCM_RATE_48000 | SNDRV_PCM_RATE_88200 | SNDRV_PCM_RATE_96000
++
++
++pcmdir:
++---------
++The stream directions supported by this mode. e.g. playback and capture
++
++
++flags:
++--------
++The DAI hardware flags supported by the mode.
++
++/* use bfs mclk divider mode (BCLK = MCLK / x) */
++#define SND_SOC_DAI_BFS_DIV 0x1
++/* use bfs rate mulitplier (BCLK = RATE * x)*/
++#define SND_SOC_DAI_BFS_RATE 0x2
++/* use bfs rcw multiplier (BCLK = RATE * CHN * WORD SIZE) */
++#define SND_SOC_DAI_BFS_RCW 0x4
++/* capture and playback can use different clocks */
++#define SND_SOC_DAI_ASYNC 0x8
++
++NOTE: Bitclock division and mulitiplication modes can be safely matched by the
++core logic.
++
++
++fs:
++-----
++The FS supported by this DAI mode FS is the ratio between the system clock and
++the sample rate. See above
++
++bfs:
++------
++BFS is the ratio of BCLK to MCLK or the ratio of BCLK to sample rate (this
++depends on the codec or CPU DAI).
++
++The BFS supported by the DAI mode. This can either be the ratio between the
++bitclock (BCLK) and the sample rate OR the ratio between the system clock and
++the sample rate. Depends on the flags above.
++
++priv:
++-----
++private codec mode data.
++
++
++
++Examples
++========
++
++Note that Codec DAI and CPU DAI examples are interchangeable in these examples
++as long as the bus master is reversed. i.e.
++
++ SND_SOC_DAIFMT_CBM_CFM would become SND_SOC_DAIFMT_CBS_CFS
++ and vice versa.
++
++This applies to all SND_SOC_DAIFMT_CB*_CF*.

++Audio Clocking
++==============
++
++This text describes the audio clocking terms in ASoC and digital audio in
++general. Note: Audio clocking can be complex !
++
++
++Master Clock
++------------
++
++Every audio subsystem is driven by a master clock (sometimes refered to as MCLK
++or SYSCLK). This audio master clock can be derived from a number of sources
++(e.g. crystal, PLL, CPU clock) and is responsible for producing the correct
++audio playback and capture sample rates.
++
++Some master clocks (e.g. PLL's and CPU based clocks) are configuarble in that
++their speed can be altered by software (depending on the system use and to save
++power). Other master clocks are fixed at at set frequency (i.e. crystals).

++The Digital Audio Interface is usually driven by a Bit Clock (often referred to
++as BCLK). This clock is used to drive the digital audio data across the link
++between the codec and CPU.
++
++The DAI also has a frame clock to signal the start of each audio frame. This
++clock is sometimes referred to as LRC (left right clock) or FRAME. This clock
++runs at exactly the sample rate (LRC = Rate).
++
++Bit Clock can be generated as follows:-
++
++BCLK = MCLK / x
++
++ or
++
++BCLK = LRC * x
++
++ or
++
++BCLK = LRC * Channels * Word Size
++
++This relationship depends on the codec or SoC CPU in particular. ASoC can quite
++easily match BCLK generated by division (SND_SOC_DAI_BFS_DIV) with BCLK by
++multiplication (SND_SOC_DAI_BFS_RATE) or BCLK generated by
++Rate * Channels * Word size (RCW or SND_SOC_DAI_BFS_RCW).
++
++
++ASoC Clocking
++-------------
++
++The ASoC core determines the clocking for each particular configuration at
++runtime. This is to allow for dynamic audio clocking wereby the audio clock is
++variable and depends on the system state or device usage scenario. i.e. a voice
++call requires slower clocks (and hence less power) than MP3 playback.
++
++ASoC will call the config_sysclock() function for the target machine during the
++audio parameters configuration. The function is responsible for then clocking
++the machine audio subsytem and returning the audio clock speed to the core.
++This function should also call the codec and cpu DAI clock_config() functions
++to configure their respective internal clocking if required.
++
++
++ASoC Clocking Control Flow
++--------------------------
++
++The ASoC core will call the machine drivers config_sysclock() when most of the
++DAI capabilities are known. The machine driver is then responsible for calling
++the codec and/or CPU DAI drivers with the selected capabilities and the current
++MCLK. Note that the machine driver is also resonsible for setting the MCLK (and
++enabling it).
++
++ (1) Match Codec and CPU DAI capabilities. At this point we have
++ matched the majority of the DAI fields and now need to make sure this
++ mode is currently clockable.
++
++ (2) machine->config_sysclk() is now called with the matched DAI FS, sample
++ rate and BCLK master. This function then gets/sets the current audio
++ clock (depening on usage) and calls the codec and CPUI DAI drivers with
++ the FS, rate, BCLK master and MCLK.
++
++ (3) Codec/CPU DAI config_sysclock(). This function checks that the FS, rate,
++ BCLK master and MCLK are acceptable for the codec or CPU DAI. It also
++ sets the DAI internal state to work with said clocks.
++
++The config_sysclk() functions for CPU, codec and machine should return the MCLK
++on success and 0 on failure.
++
++
++Examples (b = BCLK, l = LRC)

++ASoC Codec Driver
++=================
++
++The codec driver is generic and hardware independent code that configures the
++codec to provide audio capture and playback. It should contain no code that is
++specific to the target platform or machine. All platform and machine specific
++code should be added to the platform and machine drivers respectively.
++
++Each codec driver must provide the following features:-
++
++ 1) Digital audio interface (DAI) description
++ 2) Digital audio interface configuration
++ 3) PCM's description
++ 4) Codec control IO - using I2C, 3 Wire(SPI) or both API's
++ 5) Mixers and audio controls
++ 6) Sysclk configuration
++ 7) Codec audio operations
++
++Optionally, codec drivers can also provide:-
++
++ 8) DAPM description.
++ 9) DAPM event handler.
++10) DAC Digital mute control.
++
++It's probably best to use this guide in conjuction with the existing codec
++driver code in sound/soc/codecs/
++
++ASoC Codec driver breakdown
++===========================
++
++1 - Digital Audio Interface (DAI) description
++---------------------------------------------
++The DAI is a digital audio data transfer link between the codec and host SoC
++CPU. It typically has data transfer capabilities in both directions
++(playback and capture) and can run at a variety of different speeds.
++Supported interfaces currently include AC97, I2S and generic PCM style links.
++Please read DAI.txt for implementation information.
++
++
++2 - Digital Audio Interface (DAI) configuration
++-----------------------------------------------
++DAI configuration is handled by the codec_pcm_prepare function and is
++responsible for configuring and starting the DAI on the codec. This can be
++called multiple times and is atomic. It can access the runtime parameters.
++
++This usually consists of a large function with numerous switch statements to
++set up each configuration option. These options are set by the core at runtime.
++
++
++3 - Codec PCM's
++---------------
++Each codec must have it's PCM's defined. This defines the number of channels,
++stream names, callbacks and codec name. It is also used to register the DAI
++with the ASoC core. The PCM structure also associates the DAI capabilities with
++the ALSA PCM.
++
++e.g.
++
++static struct snd_soc_pcm_codec wm8731_pcm_client = {
++ .name = "WM8731",
++ .playback = {
++ .stream_name = "Playback",
++ .channels_min = 1,
++ .channels_max = 2,
++ },
++ .capture = {
++ .stream_name = "Capture",
++ .channels_min = 1,
++ .channels_max = 2,
++ },
++ .config_sysclk = wm8731_config_sysclk,
++ .ops = {
++ .prepare = wm8731_pcm_prepare,
++ },
++ .caps = {
++ .num_modes = ARRAY_SIZE(wm8731_hwfmt),
++ .modes = &wm8731_hwfmt[0],
++ },
++};
++
++
++4 - Codec control IO
++--------------------
++The codec can ususally be controlled via an I2C or SPI style interface (AC97
++combines control with data in the DAI). The codec drivers will have to provide
++functions to read and write the codec registers along with supplying a register
++cache:-
++
++ /* IO control data and register cache */
++ void *control_data; /* codec control (i2c/3wire) data */
++ void *reg_cache;
++
++Codec read/write should do any data formatting and call the hardware read write
++below to perform the IO. These functions are called by the core and alsa when
++performing DAPM or changing the mixer:-
++
++ unsigned int (*read)(struct snd_soc_codec *, unsigned int);
++ int (*write)(struct snd_soc_codec *, unsigned int, unsigned int);
++
++Codec hardware IO functions - usually points to either the I2C, SPI or AC97
++read/write:-
++
++ hw_write_t hw_write;
++ hw_read_t hw_read;
++
++
++5 - Mixers and audio controls
++-----------------------------
++All the codec mixers and audio controls can be defined using the convenience
++macros defined in soc.h.
++
++ #define SOC_SINGLE(xname, reg, shift, mask, invert)
++
++Defines a single control as follows:-
++
++ xname = Control name e.g. "Playback Volume"
++ reg = codec register
++ shift = control bit(s) offset in register
++ mask = control bit size(s) e.g. mask of 7 = 3 bits
++ invert = the control is inverted
++
++Other macros include:-
++
++ #define SOC_DOUBLE(xname, reg, shift_left, shift_right, mask, invert)
++
++A stereo control
++
++ #define SOC_DOUBLE_R(xname, reg_left, reg_right, shift, mask, invert)
++
++A stereo control spanning 2 registers
++
++ #define SOC_ENUM_SINGLE(xreg, xshift, xmask, xtexts)
++
++Defines an single enumerated control as follows:-
++
++ xreg = register
++ xshift = control bit(s) offset in register
++ xmask = control bit(s) size
++ xtexts = pointer to array of strings that describe each setting
++
++ #define SOC_ENUM_DOUBLE(xreg, xshift_l, xshift_r, xmask, xtexts)
++
++Defines a stereo enumerated control
++
++
++6 - System clock configuration.
++-------------------------------
++The system clock that drives the audio subsystem can change depending on sample
++rate and the system power state. i.e.
++
++o Higher sample rates sometimes need a higher system clock.
++o Low system power states can sometimes limit the available clocks.
++
++This function is a callback that the machine driver can call to set and
++determine if the clock and sample rate combination is supported by the codec at
++the present time (and system state).
++
++NOTE: If the codec has a PLL then it has a lot more flexability wrt clock and
++sample rate combinations.
++
++Your config_sysclock function should return the MCLK if it's a valid
++combination for your codec else 0;
++
++Please read clocking.txt now.
++
++
++7 - Codec Audio Operations
++--------------------------
++The codec driver also supports the following alsa operations:-
++
++/* SoC audio ops */
++struct snd_soc_ops {
++ int (*startup)(snd_pcm_substream_t *);
++ void (*shutdown)(snd_pcm_substream_t *);
++ int (*hw_params)(snd_pcm_substream_t *, snd_pcm_hw_params_t *);
++ int (*hw_free)(snd_pcm_substream_t *);
++ int (*prepare)(snd_pcm_substream_t *);
++};
++
++Please refer to the alsa driver PCM documentation for details.
++http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
++
++
++8 - DAPM description.
++---------------------
++The Dynamic Audio Power Management description describes the codec's power
++components, their relationships and registers to the ASoC core. Please read
++dapm.txt for details of building the description.
++
++Please also see the examples in other codec drivers.
++
++
++9 - DAPM event handler
++----------------------
++This function is a callback that handles codec domain PM calls and system
++domain PM calls (e.g. suspend and resume). It's used to put the codec to sleep
++when not in use.
++
++Power states:-
++
++ SNDRV_CTL_POWER_D0: /* full On */
++ /* vref/mid, clk and osc on, active */
++
++ SNDRV_CTL_POWER_D1: /* partial On */
++ SNDRV_CTL_POWER_D2: /* partial On */
++
++ SNDRV_CTL_POWER_D3hot: /* Off, with power */
++ /* everything off except vref/vmid, inactive */
++
++ SNDRV_CTL_POWER_D3cold: /* Everything Off, without power */
++
++
++10 - Codec DAC digital mute control.
++------------------------------------
++Most codecs have a digital mute before the DAC's that can be used to minimise
++any system noise. The mute stops any digital data from entering the DAC.
++
++A callback can be created that is called by the core for each codec DAI when the
++mute is applied or freed.
++
++i.e.
++
++static int wm8974_mute(struct snd_soc_codec *codec,
++ struct snd_soc_codec_dai *dai, int mute)
++{
++ u16 mute_reg = wm8974_read_reg_cache(codec, WM8974_DAC) & 0xffbf;
++ if(mute)
++ wm8974_write(codec, WM8974_DAC, mute_reg | 0x40);
++ else
++ wm8974_write(codec, WM8974_DAC, mute_reg);
++ return 0;
++}

++Dynamic Audio Power Management for Portable Devices
++===================================================
++
++1. Description
++==============
++
++Dynamic Audio Power Management (DAPM) is designed to allow portable Linux devices
++to use the minimum amount of power within the audio subsystem at all times. It
++is independent of other kernel PM and as such, can easily co-exist with the
++other PM systems.
++
++DAPM is also completely transparent to all user space applications as all power
++switching is done within the ASoC core. No code changes or recompiling are
++required for user space applications. DAPM makes power switching descisions based
++upon any audio stream (capture/playback) activity and audio mixer settings
++within the device.
++
++DAPM spans the whole machine. It covers power control within the entire audio
++subsystem, this includes internal codec power blocks and machine level power
++systems.
++
++There are 4 power domains within DAPM
++
++ 1. Codec domain - VREF, VMID (core codec and audio power)
++ Usually controlled at codec probe/remove and suspend/resume, although
++ can be set at stream time if power is not needed for sidetone, etc.
++
++ 2. Platform/Machine domain - physically connected inputs and outputs
++ Is platform/machine and user action specific, is configured by the
++ machine driver and responds to asynchronous events e.g when HP
++ are inserted
++
++ 3. Path domain - audio susbsystem signal paths
++ Automatically set when mixer and mux settings are changed by the user.
++ e.g. alsamixer, amixer.
++
++ 4. Stream domain - DAC's and ADC's.
++ Enabled and disabled when stream playback/capture is started and
++ stopped respectively. e.g. aplay, arecord.
++
++All DAPM power switching descisons are made automatically by consulting an audio
++routing map of the whole machine. This map is specific to each machine and
++consists of the interconnections between every audio component (including
++internal codec components). All audio components that effect power are called
++widgets hereafter.
++
++
++2. DAPM Widgets
++===============
++
++Audio DAPM widgets fall into a number of types:-
++
++ o Mixer - Mixes several analog signals into a single analog signal.
++ o Mux - An analog switch that outputs only 1 of it's inputs.
++ o PGA - A programmable gain amplifier or attenuation widget.
++ o ADC - Analog to Digital Converter
++ o DAC - Digital to Analog Converter
++ o Switch - An analog switch
++ o Input - A codec input pin
++ o Output - A codec output pin
++ o Headphone - Headphone (and optional Jack)
++ o Mic - Mic (and optional Jack)
++ o Line - Line Input/Output (and optional Jack)
++ o Speaker - Speaker
++ o Pre - Special PRE widget (exec before all others)
++ o Post - Special POST widget (exec after all others)
++
++(Widgets are defined in include/sound/soc-dapm.h)
++
++Widgets are usually added in the codec driver and the machine driver. There are
++convience macros defined in soc-dapm.h that can be used to quickly build a
++list of widgets of the codecs and machines DAPM widgets.
++
++Most widgets have a name, register, shift and invert. Some widgets have extra
++parameters for stream name and kcontrols.
++
++
++2.1 Stream Domain Widgets
++-------------------------
++
++Stream Widgets relate to the stream power domain and only consist of ADC's
++(analog to digital converters) and DAC's (digital to analog converters).
++
++Stream widgets have the following format:-
++
++SND_SOC_DAPM_DAC(name, stream name, reg, shift, invert),
++
++NOTE: the stream name must match the corresponding stream name in your codecs
++snd_soc_codec_dai.
++
++e.g. stream widgets for HiFi playback and capture
++
++SND_SOC_DAPM_DAC("HiFi DAC", "HiFi Playback", REG, 3, 1),
++SND_SOC_DAPM_ADC("HiFi ADC", "HiFi Capture", REG, 2, 1),
++
++
++2.2 Path Domain Widgets
++-----------------------
++
++Path domain widgets have a ability to control or effect the audio signal or
++audio paths within the audio subsystem. They have the following form:-
++
++SND_SOC_DAPM_PGA(name, reg, shift, invert, controls, num_controls)
++
++Any widget kcontrols can be set using the controls and num_controls members.
++
++e.g. Mixer widget (the kcontrols are declared first)
++
++/* Output Mixer */
++static const snd_kcontrol_new_t wm8731_output_mixer_controls[] = {
++SOC_DAPM_SINGLE("Line Bypass Switch", WM8731_APANA, 3, 1, 0),
++SOC_DAPM_SINGLE("Mic Sidetone Switch", WM8731_APANA, 5, 1, 0),
++SOC_DAPM_SINGLE("HiFi Playback Switch", WM8731_APANA, 4, 1, 0),
++};
++
++SND_SOC_DAPM_MIXER("Output Mixer", WM8731_PWR, 4, 1, wm8731_output_mixer_controls,
++ ARRAY_SIZE(wm8731_output_mixer_controls)),
++
++
++2.3 Platform/Machine domain Widgets
++-----------------------------------
++
++Machine widgets are different from codec widgets in that they don't have a
++codec register bit associated with them. A machine widget is assigned to each
++machine audio component (non codec) that can be independently powered. e.g.
++
++ o Speaker Amp
++ o Microphone Bias
++ o Jack connectors
++
++A machine widget can have an optional call back.
++
++e.g. Jack connector widget for an external Mic that enables Mic Bias
++when the Mic is inserted:-
++
++static int spitz_mic_bias(struct snd_soc_dapm_widget* w, int event)
++{
++ if(SND_SOC_DAPM_EVENT_ON(event))
++ set_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
++ else
++ reset_scoop_gpio(&spitzscoop2_device.dev, SPITZ_SCP2_MIC_BIAS);
++
++ return 0;
++}
++
++SND_SOC_DAPM_MIC("Mic Jack", spitz_mic_bias),
++
++
++2.4 Codec Domain
++----------------
++
++The Codec power domain has no widgets and is handled by the codecs DAPM event
++handler. This handler is called when the codec powerstate is changed wrt to any
++stream event or by kernel PM events.
++
++
++2.5 Virtual Widgets
++-------------------
++
++Sometimes widgets exist in the codec or machine audio map that don't have any
++corresponding register bit for power control. In this case it's necessary to
++create a virtual widget - a widget with no control bits e.g.
++
++SND_SOC_DAPM_MIXER("AC97 Mixer", SND_SOC_DAPM_NOPM, 0, 0, NULL, 0),
++
++This can be used to merge to signal paths together in software.
++
++After all the widgets have been defined, they can then be added to the DAPM
++subsystem individually with a call to snd_soc_dapm_new_control().
++
++
++3. Codec Widget Interconnections
++================================
++
++Widgets are connected to each other within the codec and machine by audio
++paths (called interconnections). Each interconnection must be defined in order
++to create a map of all audio paths between widgets.
++This is easiest with a diagram of the codec (and schematic of the machine audio
++system), as it requires joining widgets together via their audio signal paths.
++
++i.e. from the WM8731 codec's output mixer (wm8731.c)
++
++The WM8731 output mixer has 3 inputs (sources)
++
++ 1. Line Bypass Input
++ 2. DAC (HiFi playback)
++ 3. Mic Sidetone Input
++
++Each input in this example has a kcontrol associated with it (defined in example
++above) and is connected to the output mixer via it's kcontrol name. We can now
++connect the destination widget (wrt audio signal) with it's source widgets.
++
++ /* output mixer */
++ {"Output Mixer", "Line Bypass Switch", "Line Input"},
++ {"Output Mixer", "HiFi Playback Switch", "DAC"},
++ {"Output Mixer", "Mic Sidetone Switch", "Mic Bias"},
++
++So we have :-
++
++ Destination Widget <=== Path Name <=== Source Widget
++
++Or:-
++
++ Sink, Path, Source
++
++Or :-
++
++ "Output Mixer" is connected to the "DAC" via the "HiFi Playback Switch".
++
++When there is no path name connecting widgets (e.g. a direct connection) we
++pass NULL for the path name.
++
++Interconnections are created with a call to:-
++
++snd_soc_dapm_connect_input(codec, sink, path, source);
++
++Finally, snd_soc_dapm_new_widgets(codec) must be called after all widgets and
++interconnections have been registered with the core. This causes the core to
++scan the codec and machine so that the internal DAPM state matches the
++physical state of the machine.
++
++
++3.1 Machine Widget Interconnections
++-----------------------------------
++Machine widget interconnections are created in the same way as codec ones and
++directly connect the codec pins to machine level widgets.
++
++e.g. connects the speaker out codec pins to the internal speaker.
++
++ /* ext speaker connected to codec pins LOUT2, ROUT2 */
++ {"Ext Spk", NULL , "ROUT2"},
++ {"Ext Spk", NULL , "LOUT2"},
++
++This allows the DAPM to power on and off pins that are connected (and in use)
++and pins that are NC respectively.
++
++
++4 Endpoint Widgets
++===================
++An endpoint is a start or end point (widget) of an audio signal within the
++machine and includes the codec. e.g.
++
++ o Headphone Jack
++ o Internal Speaker
++ o Internal Mic
++ o Mic Jack
++ o Codec Pins
++
++When a codec pin is NC it can be marked as not used with a call to
++
++snd_soc_dapm_set_endpoint(codec, "Widget Name", 0);
++
++The last argument is 0 for inactive and 1 for active. This way the pin and its
++input widget will never be powered up and consume power.
++
++This also applies to machine widgets. e.g. if a headphone is connected to a
++jack then the jack can be marked active. If the headphone is removed, then
++the headphone jack can be marked inactive.
++
++
++5 DAPM Widget Events
++====================
++
++Some widgets can register their interest with the DAPM core in PM events.
++e.g. A Speaker with an amplifier registers a widget so the amplifier can be
++powered only when the spk is in use.
++
++/* turn speaker amplifier on/off depending on use */
++static int corgi_amp_event(struct snd_soc_dapm_widget *w, int event)
++{
++ if (SND_SOC_DAPM_EVENT_ON(event))
++ set_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
++ else
++ reset_scoop_gpio(&corgiscoop_device.dev, CORGI_SCP_APM_ON);
++
++ return 0;
++}
++
++/* corgi machine dapm widgets */
++static const struct snd_soc_dapm_widget wm8731_dapm_widgets =
++ SND_SOC_DAPM_SPK("Ext Spk", corgi_amp_event);
++
++Please see soc-dapm.h for all other widgets that support events.
++
++
++5.1 Event types
++---------------
++
++The following event types are supported by event widgets.
++
++/* dapm event types */
++#define SND_SOC_DAPM_PRE_PMU 0x1 /* before widget power up */
++#define SND_SOC_DAPM_POST_PMU 0x2 /* after widget power up */
++#define SND_SOC_DAPM_PRE_PMD 0x4 /* before widget power down */
++#define SND_SOC_DAPM_POST_PMD 0x8 /* after widget power down */
++#define SND_SOC_DAPM_PRE_REG 0x10 /* before audio path setup */
++#define SND_SOC_DAPM_POST_REG 0x20 /* after audio path setup */

++ASoC Machine Driver
++===================
++
++The ASoC machine (or board) driver is the code that glues together the platform
++and codec drivers.
++
++The machine driver can contain codec and platform specific code. It registers
++the audio subsystem with the kernel as a platform device and is represented by
++the following struct:-
++
++/* SoC machine */
++struct snd_soc_machine {
++ char *name;
++
++ int (*probe)(struct platform_device *pdev);
++ int (*remove)(struct platform_device *pdev);
++
++ /* the pre and post PM functions are used to do any PM work before and
++ * after the codec and DAI's do any PM work. */
++ int (*suspend_pre)(struct platform_device *pdev, pm_message_t state);
++ int (*suspend_post)(struct platform_device *pdev, pm_message_t state);
++ int (*resume_pre)(struct platform_device *pdev);
++ int (*resume_post)(struct platform_device *pdev);
++
++ /* machine stream operations */
++ struct snd_soc_ops *ops;
++
++ /* CPU <--> Codec DAI links */
++ struct snd_soc_dai_link *dai_link;
++ int num_links;
++};
++
++probe()/remove()
++----------------
++probe/remove are optional. Do any machine specific probe here.
++
++
++suspend()/resume()
++------------------
++The machine driver has pre and post versions of suspend and resume to take care
++of any machine audio tasks that have to be done before or after the codec, DAI's
++and DMA is suspended and resumed. Optional.
++
++
++Machine operations
++------------------
++The machine specific audio operations can be set here. Again this is optional.
++
++
++Machine DAI Configuration
++-------------------------
++The machine DAI configuration glues all the codec and CPU DAI's together. It can
++also be used to set up the DAI system clock and for any machine related DAI
++initialisation e.g. the machine audio map can be connected to the codec audio
++map, unconnnected codec pins can be set as such. Please see corgi.c, spitz.c
++for examples.
++
++struct snd_soc_dai_link is used to set up each DAI in your machine. e.g.
++
++/* corgi digital audio interface glue - connects codec <--> CPU */
++static struct snd_soc_dai_link corgi_dai = {
++ .name = "WM8731",
++ .stream_name = "WM8731",
++ .cpu_dai = &pxa_i2s_dai,
++ .codec_dai = &wm8731_dai,
++ .init = corgi_wm8731_init,
++ .config_sysclk = corgi_config_sysclk,
++};
++
++struct snd_soc_machine then sets up the machine with it's DAI's. e.g.
++
++/* corgi audio machine driver */
++static struct snd_soc_machine snd_soc_machine_corgi = {
++ .name = "Corgi",
++ .dai_link = &corgi_dai,
++ .num_links = 1,
++ .ops = &corgi_ops,
++};
++
++
++Machine Audio Subsystem
++-----------------------
++
++The machine soc device glues the platform, machine and codec driver together.
++Private data can also be set here. e.g.
++
++/* corgi audio private data */
++static struct wm8731_setup_data corgi_wm8731_setup = {
++ .i2c_address = 0x1b,
++};
++
++/* corgi audio subsystem */
++static struct snd_soc_device corgi_snd_devdata = {
++ .machine = &snd_soc_machine_corgi,
++ .platform = &pxa2xx_soc_platform,
++ .codec_dev = &soc_codec_dev_wm8731,
++ .codec_data = &corgi_wm8731_setup,
++};
++
++
++Machine Power Map
++-----------------
++
++The machine driver can optionally extend the codec power map and to become an
++audio power map of the audio subsystem. This allows for automatic power up/down
++of speaker/HP amplifiers, etc. Codec pins can be connected to the machines jack
++sockets in the machine init function. See soc/pxa/spitz.c and dapm.txt for
++details.
++
++
++Machine Controls
++----------------
++
++Machine specific audio mixer controls can be added in the dai init function.

++ALSA SoC Layer
++==============
++
++The overall project goal of the ALSA System on Chip (ASoC) layer is to provide
++better ALSA support for embedded system on chip procesors (e.g. pxa2xx, au1x00,
++iMX, etc) and portable audio codecs. Currently there is some support in the
++kernel for SoC audio, however it has some limitations:-
++
++ * Currently, codec drivers are often tightly coupled to the underlying SoC
++ cpu. This is not ideal and leads to code duplication i.e. Linux now has 4
++ different wm8731 drivers for 4 different SoC platforms.
++
++ * There is no standard method to signal user initiated audio events.
++ e.g. Headphone/Mic insertion, Headphone/Mic detection after an insertion
++ event. These are quite common events on portable devices and ofter require
++ machine specific code to re route audio, enable amps etc after such an event.
++
++ * Current drivers tend to power up the entire codec when playing
++ (or recording) audio. This is fine for a PC, but tends to waste a lot of
++ power on portable devices. There is also no support for saving power via
++ changing codec oversampling rates, bias currents, etc.
++
++
++ASoC Design
++===========
++
++The ASoC layer is designed to address these issues and provide the following
++features :-
++
++ * Codec independence. Allows reuse of codec drivers on other platforms
++ and machines.
++
++ * Easy I2S/PCM audio interface setup between codec and SoC. Each SoC interface
++ and codec registers it's audio interface capabilities with the core and are
++ subsequently matched and configured when the application hw params are known.
++
++ * Dynamic Audio Power Management (DAPM). DAPM automatically sets the codec to
++ it's minimum power state at all times. This includes powering up/down
++ internal power blocks depending on the internal codec audio routing and any
++ active streams.
++
++ * Pop and click reduction. Pops and clicks can be reduced by powering the
++ codec up/down in the correct sequence (including using digital mute). ASoC
++ signals the codec when to change power states.
++
++ * Machine specific controls: Allow machines to add controls to the sound card
++ e.g. volume control for speaker amp.
++
++To achieve all this, ASoC basically splits an embedded audio system into 3
++components :-
++
++ * Codec driver: The codec driver is platform independent and contains audio
++ controls, audio interface capabilities, codec dapm definition and codec IO
++ functions.
++
++ * Platform driver: The platform driver contains the audio dma engine and audio
++ interface drivers (e.g. I2S, AC97, PCM) for that platform.
++
++ * Machine driver: The machine driver handles any machine specific controls and
++ audio events. i.e. turing on an amp at start of playback.

++ASoC Platform Driver
++====================
++
++An ASoC platform driver can be divided into audio DMA and SoC DAI configuration
++and control. The platform drivers only target the SoC CPU and must have no board
++specific code.
++
++Audio DMA
++=========
++
++The platform DMA driver optionally supports the following alsa operations:-
++
++/* SoC audio ops */
++struct snd_soc_ops {
++ int (*startup)(snd_pcm_substream_t *);
++ void (*shutdown)(snd_pcm_substream_t *);
++ int (*hw_params)(snd_pcm_substream_t *, snd_pcm_hw_params_t *);
++ int (*hw_free)(snd_pcm_substream_t *);
++ int (*prepare)(snd_pcm_substream_t *);
++ int (*trigger)(snd_pcm_substream_t *, int);
++};
++
++The platform driver exports it's DMA functionailty via struct snd_soc_platform:-
++
++struct snd_soc_platform {
++ char *name;
++
++ int (*probe)(struct platform_device *pdev);
++ int (*remove)(struct platform_device *pdev);
++ int (*suspend)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
++ int (*resume)(struct platform_device *pdev, struct snd_soc_cpu_dai *cpu_dai);
++
++ /* pcm creation and destruction */
++ int (*pcm_new)(snd_card_t *, struct snd_soc_codec_dai *, snd_pcm_t *);
++ void (*pcm_free)(snd_pcm_t *);
++
++ /* platform stream ops */
++ snd_pcm_ops_t *pcm_ops;
++};
++
++Please refer to the alsa driver documentation for details of audio DMA.
++http://www.alsa-project.org/~iwai/writing-an-alsa-driver/c436.htm
++
++An example DMA driver is soc/pxa/pxa2xx-pcm.c
++
++
++SoC DAI Drivers
++===============
++
++Each SoC DAI driver must provide the following features:-
++
++ 1) Digital audio interface (DAI) description
++ 2) Digital audio interface configuration
++ 3) PCM's description
++ 4) Sysclk configuration
++ 5) Suspend and resume (optional)
++
++Please see codec.txt for a description of items 1 - 4.

++Audio Pops and Clicks
++=====================
++
++Pops and clicks are unwanted audio artifacts caused by the powering up and down
++of components within the audio subsystem. This is noticable on PC's when an audio
++module is either loaded or unloaded (at module load time the sound card is
++powered up and causes a popping noise on the speakers).
++
++Pops and clicks can be more frequent on portable systems with DAPM. This is because
++the components within the subsystem are being dynamically powered depending on
++the audio usage and this can subsequently cause a small pop or click every time a
++component power state is changed.
++
++
++Minimising Playback Pops and Clicks
++===================================
++
++Playback pops in portable audio subsystems cannot be completely eliminated atm,
++however future audio codec hardware will have better pop and click supression.
++Pops can be reduced within playback by powering the audio components in a
++specific order. This order is different for startup and shutdown and follows
++some basic rules:-
++
++ Startup Order :- DAC --> Mixers --> Output PGA --> Digital Unmute
++
++ Shutdown Order :- Digital Mute --> Output PGA --> Mixers --> DAC
++
++This assumes that the codec PCM output path from the DAC is via a mixer and then
++a PGA (programmable gain amplifier) before being output to the speakers.
++
++
++Minimising Capture Pops and Clicks
++==================================
++
++Capture artifacts are somewhat easier to get rid as we can delay activating the
++ADC until all the pops have occured. This follows similar power rules to
++playback in that components are powered in a sequence depending upon stream
++startup or shutdown.
++
++ Startup Order - Input PGA --> Mixers --> ADC
++
++ Shutdown Order - ADC --> Mixers --> Input PGA
++
++
++Zipper Noise
++============
++An unwanted zipper noise can occur within the audio playback or capture stream
++when a volume control is changed near its maximum gain value. The zipper noise
++is heard when the gain increase or decrease changes the mean audio signal
++amplitude too quickly. It can be minimised by enabling the zero cross setting
++for each volume control. The ZC forces the gain change to occur when the signal
++crosses the zero amplitude line.

++ * Notes:
++ * The WM8753 is a low power, high quality stereo codec with integrated PCM
++ * codec designed for portable digital telephony applications.
++ *
++ * Dual DAI:-
++ *
++ * This driver support 2 DAI PCM's. This makes the default PCM available for
++ * HiFi audio (e.g. MP3, ogg) playback/capture and the other PCM available for
++ * voice.
++ *
++ * Please note that the voice PCM can be connected directly to a Bluetooth
++ * codec or GSM modem and thus cannot be read or written to, although it is
++ * available to be configured with snd_hw_params(), etc and kcontrols in the
++ * normal alsa manner.
++ *
++ * Fast DAI switching:-
++ *
++ * The driver can now fast switch between the DAI configurations via a
++ * an alsa kcontrol. This allows the PCM to remain open.

++ *
++ * This is example code to demonstrate connecting a baseband modem to the PCM
++ * DAI on the WM9713 codec on the Intel Mainstone platform. It is by no means
++ * complete as it requires code to control the modem.
++ *
++ * The architecture consists of the WM9713 AC97 DAI connected to the PXA27x
++ * AC97 controller and the WM9713 PCM DAI connected to the basebands DAI. The
++ * baseband is controlled via a serial port. Audio is routed between the PXA27x
++ * and the baseband via internal WM9713 analog paths.
++ *
++ * This driver is not the baseband modem driver. This driver only calls
++ * functions from the Baseband driver to set up it's PCM DAI.
++ *
++ * It's intended to use this driver as follows:-
++ *
++ * 1. open() WM9713 PCM audio device.
++ * 2. open() serial device (for AT commands).
++ * 3. configure PCM audio device (rate etc) - sets up WM9713 PCM DAI,
++ * this will also set up the baseband PCM DAI (via calling baseband driver).
++ * 4. send any further AT commands to set up baseband.
++ * 5. configure codec audio mixer paths.
++ * 6. open(), configure and read/write AC97 audio device - to Tx/Rx voice
++ *
++ * The PCM audio device is opened but IO is never performed on it as the IO is
++ * directly between the codec and the baseband (and not the CPU).

++ *
++ * Revision history
++ * 12th Aug 2005 Initial version.
++ * 25th Oct 2005 Implemented path power domain.
++ * 18th Dec 2005 Implemented machine and stream level power domain.
++ *
++ * Features:
++ * o Changes power status of internal codec blocks depending on the
++ * dynamic configuration of codec internal audio paths and active
++ * DAC's/ADC's.
++ * o Platform power domain - can support external components i.e. amps and
++ * mic/meadphone insertion events.
++ * o Automatic Mic Bias support
++ * o Jack insertion power event initiation - e.g. hp insertion will enable
++ * sinks, dacs, etc
++ * o Delayed powerdown of audio susbsytem to reduce pops between a quick
++ * device reopen.
++ *
++ * Todo:
++ * o DAPM power change sequencing - allow for configurable per
++ * codec sequences.
++ * o Support for analogue bias optimisation.
++ * o Support for reduced codec oversampling rates.
++ * o Support for reduced codec bias currents.
