+Cavium, Inc. OCTEON SOC SPI master controller.
+
+Required properties:
+- compatible : "cavium,octeon-3010-spi"
+- reg : The register base for the controller.
+- interrupts : One interrupt, used by 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@1070000001000 {
+ compatible = "cavium,octeon-3010-spi";
+ reg = <0x10700 0x00001000 0x0 0x100>;
+ interrupts = <0 58>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ eeprom@0 {
+ compatible = "st,m95256", "atmel,at25";
+ reg = <0>;
+ spi-max-frequency = <5000000>;
+ spi-cpha;
+ spi-cpol;
+
+ pagesize = <64>;
+ size = <32768>;
+ address-width = <16>;
