+* Marvell Armada 3700 SPI Controller
+
+Required Properties:
+
+- compatible: should be "marvell,armada-3700-spi"
+- reg: physical base address of the controller and length of memory mapped
+       region.
+- interrupts: The interrupt number. The interrupt specifier format depends on
+	      the interrupt controller and of its driver.
+- clocks: Must contain the clock source, usually from the North Bridge clocks.
+- num-cs: The number of chip selects that is supported by this SPI Controller
+- #address-cells: should be 1.
+- #size-cells: should be 0.
+
+Example:
+
+	spi0: spi@10600 {
+		compatible = "marvell,armada-3700-spi";
+		#address-cells = <1>;
+		#size-cells = <0>;
+		reg = <0x10600 0x5d>;
+		clocks = <&nb_perih_clk 7>;
+		interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
+		num-cs = <4>;
+	};
