Device Tree Clock bindings for arch-moxart

This binding uses the common clock binding[1].

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

MOXA ART SoCs allow to determine PLL output and APB frequencies
by reading registers holding multiplier and divisor information.


PLL:

Required properties:
- compatible : Must be "moxa,moxart-pll-clock"
- #clock-cells : Should be 0
- reg : Should contain registers location and length
- clocks : Should contain phandle + clock-specifier for the parent clock

Optional properties:
- clock-output-names : Should contain clock name


APB:

Required properties:
- compatible : Must be "moxa,moxart-apb-clock"
- #clock-cells : Should be 0
- reg : Should contain registers location and length
- clocks : Should contain phandle + clock-specifier for the parent clock

Optional properties:
- clock-output-names : Should contain clock name


For example:

	clk_pll: clk_pll@98100000 {
		compatible = "moxa,moxart-pll-clock";
		#clock-cells = <0>;
		reg = <0x98100000 0x34>;
	};

	clk_apb: clk_apb@98100000 {
		compatible = "moxa,moxart-apb-clock";
		#clock-cells = <0>;
		reg = <0x98100000 0x34>;
		clocks = <&clk_pll>;
	};
