maintainers:

description: |
This is a part of device tree bindings for S2M and S5M family of Power
Management IC (PMIC).
The Samsung S2MPS11/13/14/15 and S2MPU02 is a family of Power Management IC
which include voltage and current regulators, RTC, clock outputs and other
sub-blocks.

enum:
- samsung,s2mps11-pmic

List of child nodes that specify the regulators.
samsung,s2mps11-acokb-ground:
description: |
Indicates that ACOKB pin of S2MPS11 PMIC is connected to the ground so
the PMIC must manually set PWRHOLD bit in CTRL1 register to turn off the
power. Usually the ACOKB is pulled up to VBATT so when PWRHOLD pin goes
low, the rising ACOKB will trigger power off.
type: boolean
samsung,s2mps11-wrstbi-ground:
description: |
Indicates that WRSTBI pin of PMIC is pulled down. When the system is
suspended it will always go down thus triggerring unwanted buck warm
reset (setting buck voltages to default values).
