tps65217pmic driver provides minimal support for the
  TPS65217 chip and allows reporting regulated voltages through the
  envsys(4) API.
The TPS65217 consists of low-dropout regulators (LDO) and step-down converters with integrated switching FETs (DCDC):
tps65217pmic device first appeared in
  NetBSD 7.0.
tps65217pmic driver was written by
  Radoslaw Kujawa
  <radoslaw.kujawa@gmail.com>.
  Voltage change callback for AM335x was added by Manuel
  Bouyer. White LED (backlight) support was added by
  KIYOHARA Takashi.
Modifying voltage regulator parameters from user space was deliberately left unimplemented, as these parameters should only be set at the firmware or kernel level. Setting wrong parameters may result in permanent hardware damage.
The tps65217pmic driver offers a function
    that can be used to change the voltage from other kernel components
    (currently used by AM335x support code).
