-Device-Tree bindings for charger of Active-semi ACT8945A Multi-Function Device
-
-Required properties:
- - compatible: "active-semi,act8945a", please refer to ../mfd/act8945a.txt.
- - active-semi,chglev-gpios: charge current level phandle with args
- as described in ../gpio/gpio.txt.
-
-Optional properties:
- - active-semi,check-battery-temperature: boolean to check the battery
- temperature or not.
- - active-semi,input-voltage-threshold-microvolt: unit: mV;
- Specifies the charger's input over-voltage threshold value;
- The value can be: 6600, 7000, 7500, 8000; default: 6600
- - active-semi,precondition-timeout: unit: minutes;
- Specifies the charger's PRECONDITION safety timer setting value;
