-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
- - interrupts: a single interrupt specifier
- - pinctrl-names: should be "default"
- - pinctrl-0: pin control state for the default mode
- - 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>;
-	interrupts = <0 39 4>;
-	pinctrl-names = "default";
-	pinctrl-0 = <&pinctrl_spi0>;
-	clocks = <&peri_clk 11>;
-	resets = <&peri_rst 11>;
-};
