Hi Rob,

Sorry for resending this mail, evolution mixed it up...

+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>.

What happened to adding Phil's interrupt support into this? You don't
have to add the whole patch, just the binding part. The driver support
can come later.

Phil revoked his patch. Right now it's not clear how the interrupt/gpio
solution will look like and if they will need an device tree binding at
all...


+
+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. See Documentation/devicetree/bindings/i2c/i2c-mux.txt for more +information on i2c-mux nodes. Channels will be numerated starting from 1 to 4.
+
+Example:
+
+batman@0a {

drop leading 0.

OK.

+    compatible = "lltc,ltc1760";
+    reg = <0x0a>;


Will remove leading 0 at this places too.

+    #address-cells = <1>;
+    #size-cells = <0>;
+
+    i2c@1 {
+        #address-cells = <1>;
+        #size-cells = <0>;
+        reg = <1>;
+
+        battery@0b {

and here...

OK.


+            compatible = "ti,bq2060", "sbs,sbs-battery";
+            reg = <0x0b>;
+        };
+    };
+
+    i2c@2 {
+        #address-cells = <1>;
+        #size-cells = <0>;
+        reg = <2>;
+
+        battery@0b {
+            compatible = "ti,bq2060", "sbs,sbs-battery";
+            reg = <0x0b>;
+        };
+    };
+
+    i2c@3 {
+        #address-cells = <1>;
+        #size-cells = <0>;
+        reg = <3>;
+
+        battery@0b {
+            compatible = "ti,bq2060", "sbs,sbs-battery";
+            reg = <0x0b>;
+        };
+    };
+};
