Binding for Qualcomm Atheros AR7xxx/AR9xxx SPI controller Required properties: - compatible: has to be "qca,-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>; };
