  37. SmartReflex can perform continuous dynamic voltage
  38. scaling around the nominal operating point voltage
  39. according to silicon characteristics and operating
  40. conditions. Enabling SmartReflex reduces power
  41. consumption.
  42. Please note, that by default SmartReflex is only

  44. compensation for vdd mpu and vdd core from user space,
  45. user must write 1 to
  46. /debug/voltage/vdd_<X>/smartreflex/autocomp,
  47. where X is mpu or core for OMAP3.
