+Device-Tree bindings for Samsung Exynos SoC display controller (DECON)
+
+DECON (Display and Enhancement Controller) is the Display Controller for the
+Exynos series of SoCs which transfers the image data from a video memory
+buffer to an external LCD interface.
+
+Required properties:
+- compatible: value should be one of:
+	"samsung,exynos5433-decon", "samsung,exynos5433-decon-tv";
+- reg: physical base address and length of the DECON registers set.
+- interrupt-names: should contain the interrupt names depending on mode of work:
+		video mode: "vsync",
+		command mode: "lcd_sys",
+		command mode with software trigger: "lcd_sys", "te".
+- interrupts or interrupts-extended: list of interrupt specifiers corresponding
+		to names privided in interrupt-names, as described in
+		interrupt-controller/interrupts.txt
+- clocks: must include clock specifiers corresponding to entries in the
+	  clock-names property.
+- clock-names: list of clock names sorted in the same order as the clocks
+	       property. Must contain "pclk", "aclk_decon", "aclk_smmu_decon0x",
+	       "aclk_xiu_decon0x", "pclk_smmu_decon0x", "aclk_smmu_decon1x",
+	       "aclk_xiu_decon1x", "pclk_smmu_decon1x", clk_decon_vclk",
+	       "sclk_decon_eclk"
+- ports: contains a port which is connected to mic node. address-cells and
+	 size-cells must 1 and 0, respectively.
+- port: contains an endpoint node which is connected to the endpoint in the mic
+	node. The reg value muset be 0.
+
+Example:
+SoC specific DT entry:
+decon: decon@13800000 {
+	compatible = "samsung,exynos5433-decon";
+	reg = <0x13800000 0x2104>;
+	clocks = <&cmu_disp CLK_ACLK_DECON>, <&cmu_disp CLK_ACLK_SMMU_DECON0X>,
+		<&cmu_disp CLK_ACLK_XIU_DECON0X>,
+		<&cmu_disp CLK_PCLK_SMMU_DECON0X>,
+		<&cmu_disp CLK_ACLK_SMMU_DECON1X>,
+		<&cmu_disp CLK_ACLK_XIU_DECON1X>,
+		<&cmu_disp CLK_PCLK_SMMU_DECON1X>,
+		<&cmu_disp CLK_SCLK_DECON_VCLK>,
+		<&cmu_disp CLK_SCLK_DECON_ECLK>;
+	clock-names = "aclk_decon", "aclk_smmu_decon0x", "aclk_xiu_decon0x",
+		"pclk_smmu_decon0x", "aclk_smmu_decon1x", "aclk_xiu_decon1x",
+		"pclk_smmu_decon1x", "sclk_decon_vclk", "sclk_decon_eclk";
+	interrupt-names = "vsync", "lcd_sys";
+	interrupts = <0 202 0>, <0 203 0>;
+
+	ports {
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		port@0 {
+			reg = <0>;
+			decon_to_mic: endpoint {
+				remote-endpoint = <&mic_to_decon>;
+			};
+		};
+	};
+};
