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

  78           This option saves power, but assumes all drivers are
  79           using the clock framework. Broken drivers that do not
  80           yet use clock framework may not work with this option.
  81           If you are booting from another operating system, you
  82           probably do not want this option enabled until your
