  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.
  83          If you are booting from another operating system, you
  84          probably do not want this option enabled until your
  85          device drivers work properly.
