+ Say Y if you want to enable SmartReflex.
+
+ SmartReflex can perform continuous dynamic voltage
+ scaling around the nominal operating point voltage
+ according to silicon characteristics and operating
+ conditions. Enabling SmartReflex reduces power
+ consumption.
+
+ Please note, that by default SmartReflex is only
+ initialized. To enable the automatic voltage
+ compensation for vdd mpu and vdd core from user space,
+ user must write 1 to
+ /debug/voltage/vdd_<X>/smartreflex/autocomp,
+ where X is mpu or core for OMAP3.
+ Optionally autocompensation can be enabled in the kernel
+ by default during system init via the enable_on_init flag
+ which an be passed as platform data to the smartreflex driver.

+config OMAP_RESET_CLOCKS
+ bool "Reset unused clocks during boot"
+ depends on ARCH_OMAP
+ help
+ Say Y if you want to reset unused clocks during boot.
+ This option saves power, but assumes all drivers are
+ using the clock framework. Broken drivers that do not
+ yet use clock framework may not work with this option.
+ If you are booting from another operating system, you
+ probably do not want this option enabled until your
+ device drivers work properly.

+config OMAP_MPU_TIMER
+ bool "Use mpu timer"
+ depends on ARCH_OMAP1

+ This timer saves power compared to the OMAP_MPU_TIMER, and has
+ support for no tick during idle. The 32KHz timer provides less
