Kernel-4.18.0-80.el8_sbs,sbs-manager

Binding for sbs-manager

Required properties:

• compatible: “,“, “sbs,sbs-charger” as fallback. The part
  number compatible string might be used in order to take care of vendor
  specific registers.
• reg: integer, i2c address of the device. Should be <0xa>.
  Optional properties:
• gpio-controller: Marks the port as GPIO controller.
  See “gpio-specifier” in …/devicetree/bindings/gpio/gpio.txt.
• #gpio-cells: Should be <2>. The first cell is the pin number, the second cell
  is used to specify optional parameters:
  See “gpio-specifier” in …/devicetree/bindings/gpio/gpio.txt.

From OS view the device is basically an i2c-mux used to communicate with up to
four smart battery devices at address 0xb. The driver actually implements this
behaviour. So standard i2c-mux nodes can be used to register up to four slave
batteries. Channels will be numerated starting from 1 to 4.

Example:

batman@a {
compatible = “lltc,ltc1760”, “sbs,sbs-manager”;
reg = <0x0a>;
#address-cells = <1>;
#size-cells = <0>;

gpio-controller;
#gpio-cells = <2>;

i2c@1 {
    #address-cells = <1>;
    #size-cells = <0>;
    reg = <1>;

    battery@b {
        compatible = "ti,bq2060", "sbs,sbs-battery";
        reg = <0x0b>;
        sbs,battery-detect-gpios = <&batman 1 1>;
    };
};

i2c@2 {
    #address-cells = <1>;
    #size-cells = <0>;
    reg = <2>;

    battery@b {
        compatible = "ti,bq2060", "sbs,sbs-battery";
        reg = <0x0b>;
        sbs,battery-detect-gpios = <&batman 2 1>;
    };
};

i2c@3 {
    #address-cells = <1>;
    #size-cells = <0>;
    reg = <3>;

    battery@b {
        compatible = "ti,bq2060", "sbs,sbs-battery";
        reg = <0x0b>;
        sbs,battery-detect-gpios = <&batman 3 1>;
    };
};
