+Rockchip RK3288 EDP interface
+================================
+Required properties:
+-compatible: "rockchip,rk3288-edp";
+
+- reg: physical base address of the controller and length
+- clocks: from common clock binding: handle to dp clock.
+	of memory mapped region.
+- clock-names: from common clock binding:
+	Required elements: "clk_edp"
+			"clk_edp_24m"
+			"clk_edp_24m_parent"
+			"pclk_edp"
+- rockchip,grf: this soc should set GRF regs, so need get grf here.
+- resets: Must contain an entry for each entry in reset-names.
+	See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+  - edp
+- rockchip,panel: required a panel node
+
+Example:
+	edp: edp@...70000 {
+		compatible = "rockchip,rk3288-edp";
+                reg = <0xff970000 0x4000>;
+                interrupts = <GIC_SPI 98 IRQ_TYPE_LEVEL_HIGH>;
+                clocks = <&cru SCLK_EDP>, <&cru SCLK_EDP_24M>, <&cru PCLK_EDP_CTRL>, <&xin24m>;
+                clock-names = "clk_edp", "clk_edp_24m", "pclk_edp", "clk_edp_24m_parent";
+
+                rockchip,grf = <&grf>;
+                resets = <&cru 111>;
+                reset-names = "edp";
+		rockchip,panel = <&panel>;
