1Binding for sbs-manager
2
3Required properties:
4- compatible: "<vendor>,<part-number>", "sbs,sbs-charger" as fallback. The part
5  number compatible string might be used in order to take care of vendor
6  specific registers.
7- reg: integer, i2c address of the device. Should be <0xa>.
8Optional properties:
9- gpio-controller: Marks the port as GPIO controller.
10  See "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.
11- #gpio-cells: Should be <2>. The first cell is the pin number, the second cell
12  is used to specify optional parameters:
13  See "gpio-specifier" in .../devicetree/bindings/gpio/gpio.txt.

15From OS view the device is basically an i2c-mux used to communicate with up to
16four smart battery devices at address 0xb. The driver actually implements this
17behaviour. So standard i2c-mux nodes can be used to register up to four slave
18batteries. Channels will be numerated starting from 1 to 4.
