30 config OMAP_DEBUG_DEVICES
33 For debug cards on TI reference boards.
35 config OMAP_DEBUG_LEDS
37 depends on OMAP_DEBUG_DEVICES
38 default y if LEDS_CLASS
40 config OMAP_SMARTREFLEX
41 bool "SmartReflex support"
42 depends on (ARCH_OMAP3 || ARCH_OMAP4) && PM
44 Say Y if you want to enable SmartReflex.
46 SmartReflex can perform continuous dynamic voltage
47 scaling around the nominal operating point voltage
48 according to silicon characteristics and operating
49 conditions. Enabling SmartReflex reduces power
52 Please note, that by default SmartReflex is only
53 initialized. To enable the automatic voltage
54 compensation for vdd mpu and vdd core from user space,
56 /debug/voltage/vdd_<X>/smartreflex/autocomp,
57 where X is mpu or core for OMAP3.
58 Optionally autocompensation can be enabled in the kernel
59 by default during system init via the enable_on_init flag
60 which an be passed as platform data to the smartreflex driver.
62 config OMAP_SMARTREFLEX_CLASS3
63 bool "Class 3 mode of Smartreflex Implementation"
64 depends on OMAP_SMARTREFLEX && TWL4030_CORE
66 Say Y to enable Class 3 implementation of Smartreflex
68 Class 3 implementation of Smartreflex employs continuous hardware
71 config OMAP_RESET_CLOCKS
72 bool "Reset unused clocks during boot"
75 Say Y if you want to reset unused clocks during boot.
76 This option saves power, but assumes all drivers are
77 using the clock framework. Broken drivers that do not
78 yet use clock framework may not work with this option.
79 If you are booting from another operating system, you
80 probably do not want this option enabled until your
81 device drivers work properly.
84 bool "OMAP multiplexing support"
88 Pin multiplexing support for OMAP boards. If your bootloader
89 sets the multiplexing correctly, say N. Otherwise, or if unsure,
93 bool "Multiplexing debug output"
96 Makes the multiplexing functions print out a lot of debug info.
97 This is useful if you want to find out the correct values of the
98 multiplexing registers.
100 config OMAP_MUX_WARNINGS
101 bool "Warn about pins the bootloader didn't set up"
105 Choose Y here to warn whenever driver initialization logic needs
106 to change the pin multiplexing setup. When there are no warnings
107 printed, it's safe to deselect OMAP_MUX for your product.
114 Say Y here if you want support for the OMAP Multichannel
115 Buffered Serial Port.
118 tristate "Mailbox framework support"
121 Say Y here if you want to use OMAP Mailbox framework support for
122 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
124 config OMAP_MBOX_KFIFO_SIZE
125 int "Mailbox kfifo default buffer size (bytes)"
126 depends on OMAP_MBOX_FWK
129 Specify the default size of mailbox's kfifo buffers (bytes).
130 This can also be changed at runtime (via the mbox_kfifo_size
136 config OMAP_IOMMU_DEBUG
137 tristate "Export OMAP IOMMU internals in DebugFS"
138 depends on OMAP_IOMMU && DEBUG_FS
140 Select this to see extensive information about
141 the internal state of OMAP IOMMU in debugfs.
143 Say N unless you know you need this.
145 config OMAP_IOMMU_IVA2
148 config OMAP_MPU_TIMER
150 depends on ARCH_OMAP1
152 Select this option if you want to use the OMAP mpu timer. This
153 timer provides more intra-tick resolution than the 32KHz timer,
154 but consumes more power.
156 config OMAP_32K_TIMER
157 bool "Use 32KHz timer"
158 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
159 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
161 Select this option if you want to enable the OMAP 32KHz timer.
162 This timer saves power compared to the OMAP_MPU_TIMER, and has
163 support for no tick during idle. The 32KHz timer provides less
164 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
165 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
167 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
168 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
169 depends on ARCH_OMAP3 && PM
172 Without this option, L2 Auxiliary control register contents are
173 lost during off-mode entry on HS/EMU devices. This feature
174 requires support from PPA / boot-loader in HS/EMU devices, which
175 currently does not exist by default.
177 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
178 int "Service ID for the support routine to set L2 AUX control"
179 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
182 PPA routine service ID for setting L2 auxiliary control register.
184 config OMAP_32K_TIMER_HZ
185 int "Kernel internal timer frequency for 32KHz timer"
187 depends on OMAP_32K_TIMER
190 Kernel internal timer frequency should be a divisor of 32768,
194 bool "Use dual-mode timer"
195 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
197 Select this option if you want to use OMAP Dual-Mode timers.
199 config OMAP_SERIAL_WAKE
200 bool "Enable wake-up events for serial ports"
201 depends on ARCH_OMAP1 && OMAP_MUX
204 Select this option if you want to have your system wake up
205 to data on the serial RX line. This allows you to wake the
206 system from serial console.
209 prompt "OMAP PM layer selection"
217 bool "No-op/debug PM layer"
