  43. SmartReflex can perform continuous dynamic voltage
  44. scaling around the nominal operating point voltage
  45. according to silicon characteristics and operating
  46. conditions. Enabling SmartReflex reduces power
  47. consumption.
  48. Please note, that by default SmartReflex is only
  49. initialized. To enable the automatic voltage
  50. compensation for vdd mpu and vdd core from user space,
  51. user must write 1 to
  52. /debug/voltage/vdd_<X>/smartreflex/autocomp,
  53. where X is mpu or core for OMAP3.
