-* 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,rv1108-spi" for rv1108 SoCs.
-    "rockchip,px30-spi", "rockchip,rk3066-spi" for px30 SoCs.
-    "rockchip,rk3036-spi" for rk3036 SoCS.
-    "rockchip,rk3066-spi" for rk3066 SoCs.
-    "rockchip,rk3188-spi" for rk3188 SoCs.
-    "rockchip,rk3228-spi" for rk3228 SoCS.
-    "rockchip,rk3288-spi" for rk3288 SoCs.
-    "rockchip,rk3368-spi" for rk3368 SoCs.
-    "rockchip,rk3399-spi" for rk3399 SoCs.
-- 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.
-- #address-cells: should be 1.
-- #size-cells: should be 0.
-
-Optional Properties:
-
-- 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.
-- rx-sample-delay-ns: nanoseconds to delay after the SCLK edge before sampling
-		Rx data (may need to be fine tuned for high capacitance lines).
-		No delay (0) by default.
-- pinctrl-names: Names for the pin configuration(s); may be "default" or
-		"sleep", where the "sleep" configuration may describe the state
-		the pins should be in during system suspend. See also
-		pinctrl/pinctrl-bindings.txt.
-
-
-Example:
-
-	spi0: spi@ff110000 {
-		compatible = "rockchip,rk3066-spi";
-		reg = <0xff110000 0x1000>;
-		dmas = <&pdma1 11>, <&pdma1 12>;
-		dma-names = "tx", "rx";
-		rx-sample-delay-ns = <10>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-		interrupts = <GIC_SPI 44 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&cru SCLK_SPI0>, <&cru PCLK_SPI0>;
-		clock-names = "spiclk", "apb_pclk";
-		pinctrl-0 = <&spi1_pins>;
-		pinctrl-1 = <&spi1_sleep>;
-		pinctrl-names = "default", "sleep";
-	};
