famile? was that suppose to be family?
+
+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>;
