-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>;
- };
- };
-};
