Kernel-4.18.0-80.el8_bq2415x

Binding for TI bq2415x Li-Ion Charger

Required properties:

  • compatible: Should contain one of the following:
  • “ti,bq24150”
  • “ti,bq24150”
  • “ti,bq24150a”
  • “ti,bq24151”
  • “ti,bq24151a”
  • “ti,bq24152”
  • “ti,bq24153”
  • “ti,bq24153a”
  • “ti,bq24155”
  • “ti,bq24156”
  • “ti,bq24156a”
  • “ti,bq24158”
  • reg: integer, i2c address of the device.
  • ti,current-limit: integer, initial maximum current charger can pull
             from power supply in mA.
    
  • ti,weak-battery-voltage: integer, weak battery voltage threshold in mV.
             The chip will use slow precharge if battery voltage
             is below this value.
    
  • ti,battery-regulation-voltage: integer, maximum charging voltage in mV.
  • ti,charge-current: integer, maximum charging current in mA.
  • ti,termination-current: integer, charge will be terminated when current in
             constant-voltage phase drops below this value (in mA).
    
  • ti,resistor-sense: integer, value of sensing resistor in milliohm.

Optional properties:

  • ti,usb-charger-detection: phandle to usb charger detection device.
              (required for auto mode)
    

Example from Nokia N900:

bq24150a {
compatible = “ti,bq24150a”;
reg = <0x6b>;

ti,current-limit = <100>;
ti,weak-battery-voltage = <3400>;
ti,battery-regulation-voltage = <4200>;
ti,charge-current = <650>;
ti,termination-current = <100>;
ti,resistor-sense = <68>;

ti,usb-charger-detection = <&isp1704>;
