  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           Optionallly 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.

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