+Binding for sbs-manager
+
+Required properties:
+- compatible: should be "sbs,sbs-manager" or "lltc,ltc1760" if device is a
+ ltc1760.
+- reg: integer, i2c address of the device. Should be <0xa>.
+
+Optional properties:
+- sbsm,i2c-retry-count: integer, number of retries for trying to read or write
+ to registers. Default: 1
+
+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 as 1, 2, 4 and 8.
+
+Example:
+
+batman@0a {
+ compatible = "sbs,sbs-manager";
+ reg = <0x0a>;
+ sbsm,i2c-retry-count = <3>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ channel1@1 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <1>;
+
+ battery1@0b {
+ compatible = "sbs-battery";
+ reg = <0x0b>;
+ };
+ };
+
+ channel2@2 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <2>;
+
+ battery2@0b {
+ compatible = "sbs-battery";
+ reg = <0x0b>;
+ };
+ };
+
+ channel3@4 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ reg = <4>;
+
+ battery3@0b {
+ compatible = "sbs-battery";
+ reg = <0x0b>;
+ };
+ };
+};--
