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.

"^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
