1Binding for the AXS10X Generic PLL clock
2
3This binding uses the common clock binding[1].
4
5[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
6
7Required properties:
8- compatible: should be "snps,axs10x-<name>-pll-clock"
9  "snps,axs10x-arc-pll-clock"
10  "snps,axs10x-pgu-pll-clock"
11- reg: should always contain 2 pairs address - length: first for PLL config
12registers and second for corresponding LOCK CGU register.
13- clocks: shall be the input parent clock phandle for the PLL.
14- #clock-cells: from common clock binding; Should always be set to 0.

16Example:
17	input-clk: input-clk {
18		clock-frequency = <33333333>;
19		compatible = "fixed-clock";
20		#clock-cells = <0>;
21	};
22
23	core-clk: core-clk@80 {
24		compatible = "snps,axs10x-arc-pll-clock";
25		reg = <0x80 0x10>, <0x100 0x10>;
26		#clock-cells = <0>;
27		clocks = <&input-clk>;
28	};
