+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>;
