+Binding for sbs-manager
+
+Required properties:
+- compatible: should be "lltc,ltc1760" or use "sbs,sbs-manager" as fallback.
+- 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@0a {
+ compatible = "lltc,ltc1760";
+ reg = <0x0a>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ i2c@1 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <1>;
+
+ battery@0b {
+ 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@0b {
+ 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@0b {
+ compatible = "ti,bq2060", "sbs,sbs-battery";
+ reg = <0x0b>;
+ sbs,battery-detect-gpios = <&batman 3 1>;
+ };
+ };
+};
