   1 MAXIM, MAX77686 regulators
   2
   3 This device uses two drivers:
   4 - drivers/power/pmic/max77686.c (as parent I/O device)
   5 - drivers/power/regulator/max77686.c (for child regulators)
   6
   7 This file describes the binding info for the REGULATOR driver.
   8
   9 First, please read the binding info for the pmic:
  10 - doc/device-tree-bindings/pmic/max77686.txt
  11
  12 Required subnode:
  13 - voltage-regulators: required for the PMIC driver
  14
  15 Required properties:
  16 - regulator-name: used for regulator uclass platform data '.name'
  17
  18 Optional:
  19 - regulator-min-microvolt: minimum allowed Voltage to set
  20 - regulator-max-microvolt: minimum allowed Voltage to set
  21 - regulator-always-on: regulator should be never disabled
  22 - regulator-boot-on: regulator should be enabled by the bootloader
