+* Rockchip SPI Controller
+
+The Rockchip SPI controller is used to interface with various devices such as flash
+and display controllers using the SPI communication interface.

+Required Properties:
+
+- compatible: should be one of the following.
+    "rockchip,rk3066-spi" for rk3066.

+    "rockchip,rk3288-spi", "rockchip,rk3066-spi" for rk3288.
+- reg: physical base address of the controller and length of memory mapped
+       region.
+- interrupts: The interrupt number to the cpu. The interrupt specifier format
+              depends on the interrupt controller.
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names: Shall be "spiclk" for the transfer-clock, and "apb_pclk" for
+			   the peripheral clock.
+- dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
+		Documentation/devicetree/bindings/dma/dma.txt
+- dma-names: DMA request names should include "tx" and "rx" if present.
+- #address-cells: should be 1.
+- #size-cells: should be 0.
+
+Example:
+
+	spi0: spi@ff110000 {
+		compatible = "rockchip,rk3066-spi";
+		reg = <0xff110000 0x1000>;
