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>;
};
};
};
