+* ARM CLPS711X Serial Peripheral Interface (SPI)
+
+Required properties:
+- compatible: Should be "cirrus,clps711x-spi".
+- reg: Offset and length of the register set for the device.
+- interrupts: Should contain SPI interrupt.
+- clocks: Phandle to SPI clock.
+- syscon: Phandle to SYSCON node used for SPI control (SYSCON3).
+- cs-gpios: Specifies the GPIO pins to be used for chipselects.
+
+Example:
+ spi: spi@80000500 {
+ compatible = "cirrus,clps711x-spi";
+ reg = <0x80000500 0x4>;
+ interrupts = <15>;
+ clocks = <&clks 10>;
+ syscon = <&syscon3>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ cs-gpios = <&portb 4 GPIO_ACTIVE_LOW>,
+ <&portb 5 GPIO_ACTIVE_LOW>;
+ };
