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
vinl4m - ldo3m, ldo8m
vinl5m - ldo16m
