dt-bindings: mfd: samsung,s2mps11: Convert to dtschema
Convert the MFD part of Samsung S2MPS11/S2MPS13/S2MPS14/S2MPS15/S2MPU02 family of PMICs to DT schema format. Previously the bindings were mostly in mfd/samsung,sec-core.txt. The conversion copies parts of description from existing bindings therefore the license is not changed from GPLv2.

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.

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).
