     Device Tree Clock bindings for arch-moxart
     
     This binding uses the common clock binding[1].
     
     [1] Documentation/devicetree/bindings/clock/clock-bindings.txt
     
     MOXA ART SoCs allow to determine PLL output and APB frequencies
     by reading registers holding multiplier and divisor information.
     
    
    PLL:
    
    Required properties:
    - compatible : Must be "moxa,moxart-pll-clock"
    - #clock-cells : Should be 0
    - reg : Should contain registers location and length
    - clocks : Should contain phandle + clock-specifier for the parent clock
    
    Optional properties:
    - clock-output-names : Should contain clock name
    
    
    APB:
    
    Required properties:
    - compatible : Must be "moxa,moxart-apb-clock"
    - #clock-cells : Should be 0
    - reg : Should contain registers location and length
    - clocks : Should contain phandle + clock-specifier for the parent clock
    
    Optional properties:
    - clock-output-names : Should contain clock name
    
    
    For example:
    
            clk_pll: clk_pll@98100000 {
                    compatible = "moxa,moxart-pll-clock";
                    #clock-cells = <0>;
                    reg = <0x98100000 0x34>;
            };
    
            clk_apb: clk_apb@98100000 {
                    compatible = "moxa,moxart-apb-clock";
                    #clock-cells = <0>;
                    reg = <0x98100000 0x34>;
                    clocks = <&clk_pll>;
            };
