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

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