description: |
  This is part of the device tree bindings for the S2MPG11 Power Management IC
  (PMIC).
 
  The Samsung S2MPG11 is a Power Management IC for mobile applications with buck
  converters, various LDOs, power meters, NTC thermistor inputs, and additional
  GPIO interfaces and typically complements an S2MPG10 PMIC in a main/sub
  configuration as the sub-PMIC.

patternProperties:
  "^vinb(([1-9]|10)s|[abd])-supply$":
    description:
      Phandle to the power supply for each buck rail of this PMIC. There is a
      1:1 mapping of numbered supply to rail, e.g. vinb1s-supply supplies
      buck1s. The remaining mapping is as follows
        vinba - bucka
        vinbb - buck boost
        vinbd - buckd
 
  "^vinl[1-6]s-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
        vinl1s - ldo1s, ldo2s
        vinl2s - ldo8s, ldo9s
        vinl3s - ldo3s, ldo5s, ldo7s, ldo15s
        vinl4s - ldo10s, ldo11s, ldo12s, ldo14s

        vinl6s - ldo13s
