     Binding for the AXS10X Generic PLL clock
     
     This binding uses the common clock binding[1].
     
     [1] Documentation/devicetree/bindings/clock/clock-bindings.txt
     
     Required properties:
     - compatible: should be "snps,axs10x-<name>-pll-clock"
       "snps,axs10x-arc-pll-clock"
      "snps,axs10x-pgu-pll-clock"
    - reg: should always contain 2 pairs address - length: first for PLL config
    registers and second for corresponding LOCK CGU register.
    - clocks: shall be the input parent clock phandle for the PLL.
    - #clock-cells: from common clock binding; Should always be set to 0.
    
    Example:
            input-clk: input-clk {
                    clock-frequency = <33333333>;
                    compatible = "fixed-clock";
                    #clock-cells = <0>;
            };
    
            core-clk: core-clk@80 {
                    compatible = "snps,axs10x-arc-pll-clock";
                    reg = <0x80 0x10>, <0x100 0x10>;
                    #clock-cells = <0>;
                    clocks = <&input-clk>;
            };
