+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@...06000 {
+ compatible = "socionext,uniphier-scssi";
+ reg = <0x54006000 0x100>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ clocks = <&peri_clk 11>;
+ resets = <&peri_rst 11>;
+};
