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

  82           Say Y if you want to reset unused clocks during boot.
  83           This option saves power, but assumes all drivers are
  84           using the clock framework. Broken drivers that do not
  85           yet use clock framework may not work with this option.
  86           If you are booting from another operating system, you
  87           probably do not want this option enabled until your
  88           device drivers work properly.
