28 config OMAP_DEBUG_DEVICES
31 For debug cards on TI reference boards.
33 config OMAP_DEBUG_LEDS
35 depends on OMAP_DEBUG_DEVICES
36 default y if LEDS_CLASS
38 config OMAP_SMARTREFLEX
39 bool "SmartReflex support"
40 depends on ARCH_OMAP3 && PM
42 Say Y if you want to enable SmartReflex.
44 SmartReflex can perform continuous dynamic voltage
45 scaling around the nominal operating point voltage
46 according to silicon characteristics and operating
47 conditions. Enabling SmartReflex reduces power
50 Please note, that by default SmartReflex is only
51 initialized. To enable the automatic voltage
52 compensation for vdd mpu and vdd core from user space,
54 /debug/voltage/vdd_<X>/smartreflex/autocomp,
55 where X is mpu or core for OMAP3.
56 Optionallly autocompensation can be enabled in the kernel
57 by default during system init via the enable_on_init flag
58 which an be passed as platform data to the smartreflex driver.
60 config OMAP_SMARTREFLEX_CLASS3
61 bool "Class 3 mode of Smartreflex Implementation"
62 depends on OMAP_SMARTREFLEX && TWL4030_CORE
64 Say Y to enable Class 3 implementation of Smartreflex
66 Class 3 implementation of Smartreflex employs continuous hardware
69 config OMAP_RESET_CLOCKS
70 bool "Reset unused clocks during boot"
73 Say Y if you want to reset unused clocks during boot.
74 This option saves power, but assumes all drivers are
75 using the clock framework. Broken drivers that do not
76 yet use clock framework may not work with this option.
77 If you are booting from another operating system, you
78 probably do not want this option enabled until your
79 device drivers work properly.
82 bool "OMAP multiplexing support"
86 Pin multiplexing support for OMAP boards. If your bootloader
87 sets the multiplexing correctly, say N. Otherwise, or if unsure,
91 bool "Multiplexing debug output"
94 Makes the multiplexing functions print out a lot of debug info.
95 This is useful if you want to find out the correct values of the
96 multiplexing registers.
98 config OMAP_MUX_WARNINGS
99 bool "Warn about pins the bootloader didn't set up"
103 Choose Y here to warn whenever driver initialization logic needs
104 to change the pin multiplexing setup. When there are no warnings
105 printed, it's safe to deselect OMAP_MUX for your product.
112 Say Y here if you want support for the OMAP Multichannel
113 Buffered Serial Port.
116 tristate "Mailbox framework support"
119 Say Y here if you want to use OMAP Mailbox framework support for
120 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
122 config OMAP_MBOX_KFIFO_SIZE
123 int "Mailbox kfifo default buffer size (bytes)"
124 depends on OMAP_MBOX_FWK
127 Specify the default size of mailbox's kfifo buffers (bytes).
128 This can also be changed at runtime (via the mbox_kfifo_size
134 config OMAP_IOMMU_DEBUG
135 tristate "Export OMAP IOMMU internals in DebugFS"
136 depends on OMAP_IOMMU && DEBUG_FS
138 Select this to see extensive information about
139 the internal state of OMAP IOMMU in debugfs.
141 Say N unless you know you need this.
143 config OMAP_IOMMU_IVA2
147 prompt "System timer"
148 default OMAP_32K_TIMER if !ARCH_OMAP15XX
150 config OMAP_MPU_TIMER
153 Select this option if you want to use the OMAP mpu timer. This
154 timer provides more intra-tick resolution than the 32KHz timer,
155 but consumes more power.
157 config OMAP_32K_TIMER
158 bool "Use 32KHz timer"
159 depends on 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.
169 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
170 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
171 depends on ARCH_OMAP3 && PM
174 Without this option, L2 Auxiliary control register contents are
175 lost during off-mode entry on HS/EMU devices. This feature
176 requires support from PPA / boot-loader in HS/EMU devices, which
177 currently does not exist by default.
179 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
180 int "Service ID for the support routine to set L2 AUX control"
181 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
184 PPA routine service ID for setting L2 auxiliary control register.
186 config OMAP_32K_TIMER_HZ
187 int "Kernel internal timer frequency for 32KHz timer"
189 depends on OMAP_32K_TIMER
192 Kernel internal timer frequency should be a divisor of 32768,
196 bool "Use dual-mode timer"
197 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
199 Select this option if you want to use OMAP Dual-Mode timers.
201 config OMAP_SERIAL_WAKE
202 bool "Enable wake-up events for serial ports"
203 depends on ARCH_OMAP1 && OMAP_MUX
206 Select this option if you want to have your system wake up
207 to data on the serial RX line. This allows you to wake the
208 system from serial console.
211 prompt "OMAP PM layer selection"
