Binding for sbs-manager

Required properties:

- compatible: "<vendor>,<part-number>", "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>;

        };

    };
