+Ralink SoC RT2880 and famile SPI master controller.
+
+Required properties:
+- compatible : "ralink,rt2880-spi"
+- reg : The register base for the controller.
+- #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@b00 {
+               compatible = "ralink,rt2880-spi";
+               reg = <0xb00 0x100>;
+
+               #address-cells = <1>;
+               #size-cells = <0>;
+
+               m25p80@0 {
+                       compatible = "m25p80";
+                       reg = <0>;
+                       spi-max-frequency = <10000000>;
+               };
