Subject[PATCH 2/4] dt-bindings: power: supply: maxim,max77693: convert to dtschema
Date
Convert the Charger bindings of Maxim MAX77693 MUIC to DT schema format.
The existing bindings were defined in ../bindings/mfd/max77693.txt.

+description: |
+ This is a part of device tree bindings for Maxim MAX77693 MicroUSB Integrated
+ Circuit (MUIC).
+
+ See also Documentation/devicetree/bindings/mfd/maxim,max77693.yaml for
+ additional information and example.

+
+ maxim,constant-microvolt:
+ description: |
+ Battery constant voltage in uV. The charger will operate in fast
+ charge constant current mode till battery voltage reaches this level.
+ Then the charger will switch to fast charge constant voltage mode.
+ Also vsys (system voltage) will be set to this value when DC power is
+ supplied but charger is not enabled.
+ Valid values: 3650000 - 4400000, step by 25000 (rounded down)
+ minimum: 3650000
+ maximum: 4400000
+ default: 4200000

+ description: |
+ Minimal system voltage in uV.

+ default: 3600000
+
+ maxim,thermal-regulation-celsius:
+ description: |
+ Temperature in Celsius for entering high temperature charging mode.
+ If die temperature exceeds this value the charging current will be
+ reduced by 105 mA/Celsius.

+ description: |
+ Threshold voltage in uV for triggering input voltage regulation loop.
+ If input voltage decreases below this value, the input current will
+ be reduced to reach the threshold voltage.
