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