  32. Say Y if you want to enable SmartReflex.
  33. SmartReflex can perform continuous dynamic voltage
  34. scaling around the nominal operating point voltage
  35. according to silicon characteristics and operating
  36. conditions. Enabling SmartReflex reduces power
  37. consumption.
  38. Please note, that by default SmartReflex is only
  39. initialized. To enable the automatic voltage
  40. compensation for vdd mpu and vdd core from user space,
  41. user must write 1 to
  42. /debug/voltage/vdd_<X>/smartreflex/autocomp,
  43. where X is mpu or core for OMAP3.
  44. Optionallly autocompensation can be enabled in the kernel
  45. by default during system init via the enable_on_init flag
