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

80	  This option saves power, but assumes all drivers are
81	  using the clock framework. Broken drivers that do not
82	  yet use clock framework may not work with this option.
