   1 Device-Tree bindings for charger of Active-semi ACT8945A Multi-Function Device
   2
   3 Required properties:
   4  - compatible: "active-semi,act8945a-charger".
   5  - active-semi,chglev-gpios: charge current level phandle with args
   6    as described in ../gpio/gpio.txt.
   7  - active-semi,lbo-gpios: specify the low battery voltage detect phandle
   8    with args as as described in ../gpio/gpio.txt.
   9  - interrupts: <a b> where a is the interrupt number and b is a
  10    field that represents an encoding of the sense and level
  11    information for the interrupt.
  12  - interrupt-parent: the phandle for the interrupt controller that
  13    services interrupts for this device.
  14
  15 Optional properties:
  16  - active-semi,input-voltage-threshold-microvolt: unit: mV;
  17    Specifies the charger's input over-voltage threshold value;
  18    The value can be: 6600, 7000, 7500, 8000; default: 6600
  19  - active-semi,precondition-timeout: unit: minutes;
  20    Specifies the charger's PRECONDITION safety timer setting value;
  21    The value can be: 40, 60, 80, 0; If 0, it means to disable this timer;
  22    default: 40.
  23  - active-semi,total-timeout: unit: hours;
  24    Specifies the charger's total safety timer setting value;
  25    The value can be: 3, 4, 5, 0; If 0, it means to disable this timer;
  26    default: 3.
