+Device tree bindings for i2c-cbus-gpio driver
+
+Required properties:
+        - compatible = "i2c-cbus-gpio";
+        - gpios: clk, dat, sel
+        - #address-cells = <1>;
+        - #size-cells = <0>;
+
+Optional properties:
+        - child nodes conforming to i2c bus binding
+
+Example:
+
+i2c@0 {
+        compatible = "i2c-cbus-gpio";
+        gpios = <&gpio 66 0 /* clk */
+                 &gpio 65 0 /* dat */
+                 &gpio 64 0 /* sel */
+                >;
+        #address-cells = <1>;
+        #size-cells = <0>;
+
+        retu-mfd: retu@1 {
+                compatible = "retu-mfd";
+                reg = <0x1>;
+        };
+};
