  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>;
  	};
