7 Required 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
12 registers 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.

17         input-clk: input-clk {
18                 clock-frequency = <33333333>;
19                 compatible = "fixed-clock";
20                 #clock-cells = <0>;
21         };

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>;
