node names without 0x -> "spdif@...1e000"

if you're submitting a v2, could you try ordering stuff like this?

+		compatible = "rockchip,rk3188-spdif", "rockchip,rk3066-spdif";
+		reg = <0x1011e000 0x2000>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		#sound-dai-cells = <0>;
+		clock-names = "spdif_hclk", "spdif_clk";
+		clocks = <&cru HCLK_SPDIF>, <&cru SCLK_SPDIF>;
+		dmas = <&dmac1_s 8>;
+		dma-names = "tx";
+		interrupts = <GIC_SPI 32 IRQ_TYPE_LEVEL_HIGH>;
+		pinctrl-names = "default";
+		pinctrl-0 = <&spdif_tx>;
+		status = "disabled";

The ordering I try to keep is "compatible", "reg", [everything else sorted 
alphabetically], "status"
