+Rockchip Serial Flash Controller
+
+Required properties:
+- compatible : Should be
+		"rockchip,rv1108-sfc", "rockchip,sfc" for ROCKCHIP RV1108.
+- address-cells : Should be 1.
+- size-cells : Should be 0.
+- clocks: Must contain two entries for each entry in clock-names.
+- clock-names: Shall be "sfc" for the transfer-clock, and "hsfc" for
+		the peripheral clock.
+- interrupts : Should contain the interrupt for the device.
+- reg: Physical base address of the controller and length of memory mapped.
+
+Optional properties:
+- rockchip,sfc-no-dma: Indicate the controller doesn't support DMA transfer.
+
+Example:
+nor_flash: sfc@301c0000 {
+	compatible = "rockchip,rv1108-sfc", "rockchip,sfc";
+	#address-cells = <1>;
+	#size-cells = <0>;
+	clocks = <&cru SCLK_SFC>, <&cru HCLK_SFC>;
+	clock-names = "sfc", "hsfc";
+	interrupts = <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>;
+	reg = <0x301c0000 0x1000>;
+	spi-nor@0 {
+		compatible = "jedec,spi-nor";
+		spi-max-frequency = <12000000>;
+		reg = <0>;
+	};
+};
