-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>;
-       };
