+Binding for simple gpio clock multiplexer.
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be "gpio-mux-clock".
+- clocks: list of two references to parent clocks.
+- #clock-cells : from common clock binding; shall be set to 0.
+- select-gpios : GPIO reference for selecting the parent clock.
+
+Example:
+       clock {
+               compatible = "gpio-mux-clock";
+               clocks = <&parentclk1>, <&parentclk2>;
+               #clock-cells = <0>;
+               select-gpios = <&gpio 1 GPIO_ACTIVE_HIGH>;
+       };
