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.
Optionallly 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.
