This is part of the device tree bindings for the S2MG11 Power Management IC
|
|
(PMIC).
|
|
|
|
The S2MPG11 PMIC provides 12 buck, 1 buck-boost, and 15 LDO regulators.
|
|
|
|
See also Documentation/devicetree/bindings/mfd/samsung,s2mps11.yaml for

should monitor. The following values generally corresponding to the

respective on-chip pin are valid:
