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
|
|
