     Binding for Qualcomm Atheros AR7xxx/AR9XXX PLL controller
     
     The PPL controller provides the 3 main clocks of the SoC: CPU, DDR and AHB.
     
     Required Properties:
     - compatible: has to be "qca,<soctype>-pll" and one of the following
       fallbacks:
       - "qca,ar7100-pll"
       - "qca,ar7240-pll"
      - "qca,ar9130-pll"
      - "qca,ar9330-pll"
      - "qca,ar9340-pll"
      - "qca,qca9550-pll"
    - reg: Base address and size of the controllers memory area
    - clock-names: Name of the input clock, has to be "ref"
    - clocks: phandle of the external reference clock
    - #clock-cells: has to be one
    
    Optional properties:
    - clock-output-names: should be "cpu", "ddr", "ahb"
    
    Example:
    
            pll-controller@18050000 {
                    compatible = "qca,ar9132-pll", "qca,ar9130-pll";
                    reg = <0x18050000 0x20>;
    
                    clock-names = "ref";
                    clocks = <&extosc>;
    
                    #clock-cells = <1>;
                    clock-output-names = "cpu", "ddr", "ahb";
            };
