     Binding for Qualcomm Atheros AR7xxx/AR9xxx SPI controller
     
     Required properties:
     - compatible: has to be "qca,<soc-type>-spi", "qca,ar7100-spi" as fallback.
     - reg: Base address and size of the controllers memory area
     - clocks: phandle of the AHB clock.
     - clock-names: has to be "ahb".
     - #address-cells: <1>, as required by generic SPI binding.
     - #size-cells: <0>, also as required by generic SPI binding.
    
    Child nodes as per the generic SPI binding.
    
    Example:
    
            spi@1f000000 {
                    compatible = "qca,ar9132-spi", "qca,ar7100-spi";
                    reg = <0x1f000000 0x10>;
    
                    clocks = <&pll 2>;
                    clock-names = "ahb";
    
                    #address-cells = <1>;
                    #size-cells = <0>;
            };
