  34. SmartReflex can perform continuous dynamic voltage
  35. scaling around the nominal operating point voltage
  36. according to silicon characteristics and operating
  37. conditions. Enabling SmartReflex reduces power
  38. consumption.
  39. Please note, that by default SmartReflex is only
  40. initialized. To enable the automatic voltage
  41. compensation for vdd mpu and vdd core from user space,
  42. user must write 1 to
  43. /debug/voltage/vdd_<X>/smartreflex/autocomp,
  44. where X is mpu or core for OMAP3.
