Binding for simple fixed factor rate clock sources.



This binding uses the common clock binding[1].



[1] Documentation/devicetree/bindings/clock/clock-bindings.txt



Required properties:

- compatible : shall be "fixed-factor-clock".

- #clock-cells : from common clock binding; shall be set to 0.

- clock-div: fixed divider.

- clock-mult: fixed multiplier.

- clocks: parent clock.



Optional properties:

- clock-output-names : From common clock binding.



Some clocks that require special treatments are also handled by that

driver, with the compatibles:

  - allwinner,sun4i-a10-pll3-2x-clk



Example:

	clock {

		compatible = "fixed-factor-clock";

		clocks = <&parentclk>;

		#clock-cells = <0>;

		clock-div = <2>;

		clock-mult = <1>;

	};
