  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.

properties:
  compatible:
    const: maxim,max77693-charger

  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

  maxim,min-system-microvolt:
    description: |
      Minimal system voltage in uV.
    enum: [3000000, 3100000, 3200000, 3300000, 3400000, 3500000,
           3600000, 3700000]
    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.
    enum: [70, 85, 100, 115]
    default: 100

  maxim,battery-overcurrent-microamp:
    description: |
      Overcurrent protection threshold in uA (current from battery to
      system).
      Valid values: 2000000 - 3500000, step by 250000 (rounded down)
    minimum: 2000000
    maximum: 3500000
    default: 3500000

  maxim,charge-input-threshold-microvolt:
    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.
    enum: [4300000, 4700000, 4800000, 4900000]
    default: 4300000
