OMAP3: DMA: Errata i541: sDMA FIFO draining does not finish
Implement the suggested workaround for OMAP3 regarding to sDMA draining
issue, when the channel is disabled on the fly.
This errata affects the following configuration:
sDMA transfer is source synchronized
Buffering is enabled
SmartStandby is selected.
The issue can be easily reproduced by creating overrun situation while
recording audio.
Either introduce load to the CPU:
nice -19 arecord -D hw:0 -M -B 10000 -F 5000 -f dat > /dev/null & \
dd if=/dev/urandom of=/dev/null
or suspending the arecord, and resuming it:
arecord -D hw:0 -M -B 10000 -F 5000 -f dat > /dev/null
CTRL+Z; fg; CTRL+Z; fg; ...
In case of overrun audio stops DMA, and restarts it (without reseting
the sDMA channel). When we hit this errata in stop case (sDMA drain did
not complete), at the coming start the sDMA will not going to be
operational (it is still draining).
This leads to DMA stall condition.
On OMAP3 we can recover with sDMA channel reset, it has been observed
that by introducing unrelated sDMA activity might also help (reading
from MMC for example).
The same errata exists for OMAP2, where the suggestion is to disable the
buffering to avoid this type of error.
On OMAP3 the suggestion is to set sDMA to NoStandby before disabling
the channel, and wait for the drain to finish, than configure sDMA to
SmartStandby again.

omap: dma: Fix buffering disable bit setting for omap24xx
An errata workaround for omap24xx is not setting the buffering disable bit
25 what is the purpose but channel enable bit 7 instead.
Background for this fix is the DMA stalling issue with ASoC omap-mcbsp
driver. Peter Ujfalusi <peter.ujfalusi@nokia.com> has found an issue in
recording that the DMA stall could happen if there were a buffer overrun
detected by ALSA and the DMA was stopped and restarted due that. This
problem is known to occur on both OMAP2420 and OMAP3. It can recover on
OMAP3 after dma free, dma request and reconfiguration cycle. However, on
OMAP2420 it seems that only way to recover is a reset.
Problem was not visible before the commit c12abc0. That commit changed that
the McBSP transmitter/receiver is released from reset only when needed. That
is, only enabled McBSP transmitter without transmission was able to prevent
this DMA stall problem in receiving side and underlying problem did not show
up until now. McBSP transmitter itself seems to no be reason since DMA
stall does not recover by enabling the transmission after stall.
Debugging showed that there were a DMA write active during DMA stop time and
it never completed even when restarting the DMA. Experimenting showed that
the DMA buffering disable bit could be used to avoid stalling when using
source synchronized transfers. However that could have performance hit and
OMAP3 TRM states that buffering disable is not allowed for destination
synchronized transfers so subsequent patch will implement a method to
complete DMA writes when stopping.
This patch is based on assumtion that complete lock-up on OMAP2420 is
different but related problem. I don't have access to OMAP2420 errata but
I believe this old workaround here is put for a reason but unfortunately
a wrong bit was typed and problem showed up only now.

This is happening because 'omap_serial_init()' is hanging in the boot.
On OMAP3 the watchdog is generating reboot because devices_init doesn't
happens where as on OMAP4 it just hangs without reboot.
The uart clock is not getting enabled after omap_device_idle as part
of omap_serial_init.
The omap_device_idle(will disable the clock) then omap_uart_block_sleep()
should enable clock back disabled during the boot up phase.
But omap_uart_block_sleep() stuffed version is binded only under
CONFIG_PM and other version is just empty. Hence it is not enabling
clock back as expected
This patch adds uart clock enable code to omap_uart_block_sleep() function
built with CONFIG_PM disabled.

Previously the OMAP McBSP ASoC driver implemented CLKS switching by

These symbols are no longer exported, so as a result, the OMAP McBSP ASoC

Due to the unfortunate way that McBSP support is implemented in ASoC

omap: Update omap2plus_defconfig to use ttyO instead ttyS
With the omap-serial the device has changed from ttyS to ttyO as
the system may have both omap-serial and 8250 ports.
Note that systems using omap-serial need to be updated to use ttyO[012]
instead of ttyS[012] in the bootloader, CONFIG_CMDLINE, /etc/inittab,
and the root file system with mknod. Also you may need to add ttyO[012]
to /etc/securetty.

OMAP2: PM: check UART status before trying to idle
As is done on OMAP3, check omap_uart_can_sleep() as one of the
pre-conditions for entering the idle loop. Without this check,
entering idle introduces large latencies on active UARTs, and is
especially noticable on serial console.

OMAP2PLUS: WDT: Fix: Disable WDT after reset during init
Inorder to avoid any assumptions from bootloader, the watchdog
timer module is reset during init. This enables the watchdog
timer.
Therefore, it is required to disable WDT after it is reset
during init. Otherwise the system would reboot as per the default
watchdog timer registers settings.
Later, when the watchdog driver is loaded, the watchdog timer settings
is adjusted as per the default timer_margin set in the driver and the
driver would supports the normal operations supported by OMAP watchdog
timer.

ARM: Fix HWCAP_TLS flag for ARM11MPCore/Cortex-A9
Commit
14eff1812679c76564b775aa95cdd378965f6cfb added proper
detection for ARM11MPCore/Cortex-A9 instead of detecting them
as ARMv7. However, it was missing the HWCAP_TLS flags.
HWCAP_TLS is needed if support for earlier ARMv6 is compiled
into the same kernel. Without HWCAP_TLS flags the userspace
won't work unless nosmp is specified:

i2c: Fix for suspend/resume issue
In current i2c core driver, call to pm_runtime_set_active from

These symbols are no longer exported, so as a result, the OMAP McBSP ASoC

Due to the unfortunate way that McBSP support is implemented in ASoC

Going forward, the McBSP device driver should be moved from
