+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
+- #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>;
+
+ #address-cells = <1>;
+ #size-cells = <0>;
+ };
