+title: Samsung S2MPS11/13/14/15 and S2MPU02 Power Management IC
+
+maintainers:
+ - Krzysztof Kozlowski <krzk@kernel.org>
+
+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.

+ 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).
