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

11 PLL:
12
13 Required 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
19 Optional properties:
20 - clock-output-names : Should contain clock name
21

23 APB:
24
25 Required 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

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

35 For example:
36
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 };
