+ 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.
