44
45	  SmartReflex can perform continuous dynamic voltage
46	  scaling around the nominal operating point voltage
47	  according to silicon characteristics and operating
48	  conditions. Enabling SmartReflex reduces power
49	  consumption.
50
51	  Please note, that by default SmartReflex is only
52	  initialized. To enable the automatic voltage
53	  compensation for vdd mpu  and vdd core from user space,
54	  user must write 1 to
55		/debug/voltage/vdd_<X>/smartreflex/autocomp,
56	  where X is mpu or core for OMAP3.
57	  Optionally autocompensation can be enabled in the kernel
58	  by default during system init via the enable_on_init flag
59	  which an be passed as platform data to the smartreflex driver.
