Device-Tree bindings for charger of Active-semi ACT8945A Multi-Function Device
|
|
|
|
Required properties:
|
|
- compatible: "active-semi,act8945a-charger".
|
|
- active-semi,chglev-gpios: charge current level phandle with args
|
|
as described in ../gpio/gpio.txt.
|
|
- active-semi,lbo-gpios: specify the low battery voltage detect phandle
|
|
with args as as described in ../gpio/gpio.txt.
|
|
- interrupts: <a b> where a is the interrupt number and b is a
|
|
field that represents an encoding of the sense and level
|
|
information for the interrupt.
|
|
- interrupt-parent: the phandle for the interrupt controller that
|
|
services interrupts for this device.
|
|
|
|
Optional properties:
|
|
- 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;
|
|
The value can be: 40, 60, 80, 0; If 0, it means to disable this timer;
|
|
default: 40.
|
|
- active-semi,total-timeout: unit: hours;
|
|
Specifies the charger's total safety timer setting value;
|
|
The value can be: 3, 4, 5, 0; If 0, it means to disable this timer;
|
|
default: 3.
|
