37 config OMAP_DEBUG_DEVICES
40 For debug cards on TI reference boards.
42 config OMAP_DEBUG_LEDS
44 depends on OMAP_DEBUG_DEVICES
45 default y if LEDS_CLASS
47 config OMAP_SMARTREFLEX
48 bool "SmartReflex support"
49 depends on (ARCH_OMAP3 || ARCH_OMAP4) && PM
51 Say Y if you want to enable SmartReflex.
53 SmartReflex can perform continuous dynamic voltage
54 scaling around the nominal operating point voltage
55 according to silicon characteristics and operating
56 conditions. Enabling SmartReflex reduces power
59 Please note, that by default SmartReflex is only
60 initialized. To enable the automatic voltage
61 compensation for vdd mpu and vdd core from user space,
63 /debug/voltage/vdd_<X>/smartreflex/autocomp,
64 where X is mpu or core for OMAP3.
65 Optionally autocompensation can be enabled in the kernel
66 by default during system init via the enable_on_init flag
67 which an be passed as platform data to the smartreflex driver.
69 config OMAP_SMARTREFLEX_CLASS3
70 bool "Class 3 mode of Smartreflex Implementation"
71 depends on OMAP_SMARTREFLEX && TWL4030_CORE
73 Say Y to enable Class 3 implementation of Smartreflex
75 Class 3 implementation of Smartreflex employs continuous hardware
78 config OMAP_RESET_CLOCKS
79 bool "Reset unused clocks during boot"
82 Say Y if you want to reset unused clocks during boot.
83 This option saves power, but assumes all drivers are
84 using the clock framework. Broken drivers that do not
85 yet use clock framework may not work with this option.
86 If you are booting from another operating system, you
87 probably do not want this option enabled until your
88 device drivers work properly.
91 bool "OMAP multiplexing support"
95 Pin multiplexing support for OMAP boards. If your bootloader
96 sets the multiplexing correctly, say N. Otherwise, or if unsure,
100 bool "Multiplexing debug output"
103 Makes the multiplexing functions print out a lot of debug info.
104 This is useful if you want to find out the correct values of the
105 multiplexing registers.
107 config OMAP_MUX_WARNINGS
108 bool "Warn about pins the bootloader didn't set up"
112 Choose Y here to warn whenever driver initialization logic needs
113 to change the pin multiplexing setup. When there are no warnings
114 printed, it's safe to deselect OMAP_MUX for your product.
121 Say Y here if you want support for the OMAP Multichannel
122 Buffered Serial Port.
125 tristate "Mailbox framework support"
128 Say Y here if you want to use OMAP Mailbox framework support for
129 DSP, IVA1.0 and IVA2 in OMAP1/2/3.
131 config OMAP_MBOX_KFIFO_SIZE
132 int "Mailbox kfifo default buffer size (bytes)"
133 depends on OMAP_MBOX_FWK
136 Specify the default size of mailbox's kfifo buffers (bytes).
137 This can also be changed at runtime (via the mbox_kfifo_size
140 config OMAP_IOMMU_IVA2
143 config OMAP_MPU_TIMER
145 depends on ARCH_OMAP1
147 Select this option if you want to use the OMAP mpu timer. This
148 timer provides more intra-tick resolution than the 32KHz timer,
149 but consumes more power.
151 config OMAP_32K_TIMER
152 bool "Use 32KHz timer"
153 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
154 default y if (ARCH_OMAP16XX || ARCH_OMAP2PLUS)
156 Select this option if you want to enable the OMAP 32KHz timer.
157 This timer saves power compared to the OMAP_MPU_TIMER, and has
158 support for no tick during idle. The 32KHz timer provides less
159 intra-tick resolution than OMAP_MPU_TIMER. The 32KHz timer is
160 currently only available for OMAP16XX, 24XX, 34XX and OMAP4.
162 config OMAP3_L2_AUX_SECURE_SAVE_RESTORE
163 bool "OMAP3 HS/EMU save and restore for L2 AUX control register"
164 depends on ARCH_OMAP3 && PM
167 Without this option, L2 Auxiliary control register contents are
168 lost during off-mode entry on HS/EMU devices. This feature
169 requires support from PPA / boot-loader in HS/EMU devices, which
170 currently does not exist by default.
172 config OMAP3_L2_AUX_SECURE_SERVICE_SET_ID
173 int "Service ID for the support routine to set L2 AUX control"
174 depends on OMAP3_L2_AUX_SECURE_SAVE_RESTORE
177 PPA routine service ID for setting L2 auxiliary control register.
179 config OMAP_32K_TIMER_HZ
180 int "Kernel internal timer frequency for 32KHz timer"
182 depends on OMAP_32K_TIMER
185 Kernel internal timer frequency should be a divisor of 32768,
189 bool "Use dual-mode timer"
190 depends on ARCH_OMAP16XX || ARCH_OMAP2PLUS
192 Select this option if you want to use OMAP Dual-Mode timers.
194 config OMAP_SERIAL_WAKE
195 bool "Enable wake-up events for serial ports"
196 depends on ARCH_OMAP1 && OMAP_MUX
199 Select this option if you want to have your system wake up
200 to data on the serial RX line. This allows you to wake the
201 system from serial console.
