7MOXA ART SoCs allow to determine PLL output and APB frequencies
8by reading registers holding multiplier and divisor information.

11PLL:
12
13Required properties:
14- compatible : Must be "moxa,moxart-pll-clock"
15- #clock-cells : Should be 0
16- reg : Should contain registers location and length
17- clocks : Should contain phandle + clock-specifier for the parent clock
18
19Optional properties:
20- clock-output-names : Should contain clock name

23APB:
24
25Required properties:
26- compatible : Must be "moxa,moxart-apb-clock"
27- #clock-cells : Should be 0
28- reg : Should contain registers location and length
29- clocks : Should contain phandle + clock-specifier for the parent clock

37	clk_pll: clk_pll@98100000 {
38		compatible = "moxa,moxart-pll-clock";
39		#clock-cells = <0>;
40		reg = <0x98100000 0x34>;
41	};
42
43	clk_apb: clk_apb@98100000 {
44		compatible = "moxa,moxart-apb-clock";
45		#clock-cells = <0>;
46		reg = <0x98100000 0x34>;
47		clocks = <&clk_pll>;
48	};
