+Socionext UniPhier SPI controller driver
+
+UniPhier SoCs have SCSSI which supports SPI single channel.
+
+Required properties:
+ - compatible: should be "socionext,uniphier-scssi"
+ - reg: address and length of the spi master registers
+ - #address-cells: must be <1>, see spi-bus.txt
+ - #size-cells: must be <0>, see spi-bus.txt
+ - clocks: A phandle to the clock for the device.
+ - resets: A phandle to the reset control for the device.
+
+Example:
+
+spi0: spi@54006000 {
+	compatible = "socionext,uniphier-scssi";
+	reg = <0x54006000 0x100>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+	clocks = <&peri_clk 11>;
+	resets = <&peri_rst 11>;
+};
