description: |
  This is part of the device tree bindings for the S2MPG10 Power Management IC
  (PMIC).
 
  The Samsung S2MPG10 is a Power Management IC for mobile applications with buck
  converters, various LDOs, power meters, RTC, clock outputs, and additional
  GPIO interfaces and is typically complemented by S2MPG10 PMIC in a main/sub
  configuration as the main PMIC.

  "^vinb([1-9]|10)m-supply$":
    description:
      Phandle to the power supply for each buck rail of this PMIC. There is a
      1:1 mapping of supply to rail, e.g. vinb1m-supply supplies buck1m.
 
  "^vinl([1-9]|1[0-5])m-supply$":
    description: |
      Phandle to the power supply for one or multiple LDO rails of this PMIC.
      The mapping of supply to rail(s) is as follows:
        vinl1m - ldo13m
        vinl2m - ldo15m
        vinl3m - ldo1m, ldo5m, ldo7m

        vinl7m - ldo6m, ldo11m, ldo24m, ldo28m
        vinl8m - ldo12m
        vinl9m - ldo2m, ldo4m
        vinl10m - ldo9m, ldo14m, ldo18m, 19m, ldo20m, ldo25m
