+Device-Tree bindings for Atmel's HLCDC (High LCD Controller) DRM driver
+
+The Atmel HLCDC Display Controller is subdevice of the HLCDC MFD device.
+See ../../mfd/atmel-hlcdc.txt for more details.
+
+Required properties:
+ - compatible: value should be "atmel,hlcdc-display-controller"
+ - pinctrl-names: the pin control state names. Should contain "default".
+ - pinctrl-0: should contain the default pinctrl states.
+ - #address-cells: should be set to 1.
+ - #size-cells: should be set to 0.
+
+Required children nodes:
+ Children nodes are encoding available output ports and their connections
+ to external devices using the OF graph reprensentation (see ../graph.txt).
+ At least one port node is required.
+
+Optional properties in grandchild nodes:
+ Any endpoint grandchild node may specify a desired video interface
+ according to ../../media/video-interfaces.txt, specifically
+ - bus-width: recognized values are <12>, <16>, <18> and <24>, and
+   override any output mode selection heuristic, forcing "rgb444",
+   "rgb565", "rgb666" and "rgb888" respectively.
+
+Example:
+
+	hlcdc: hlcdc@f0030000 {
+		compatible = "atmel,sama5d3-hlcdc";
+		reg = <0xf0030000 0x2000>;
+		interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>;
+		clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>;
+		clock-names = "periph_clk","sys_clk", "slow_clk";
+
+		hlcdc-display-controller {
+			compatible = "atmel,hlcdc-display-controller";
+			pinctrl-names = "default";
+			pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb888>;
+			#address-cells = <1>;
+			#size-cells = <0>;
+
+			port@0 {
+				#address-cells = <1>;
+				#size-cells = <0>;
+				reg = <0>;
+
+				hlcdc_panel_output: endpoint@0 {
+					reg = <0>;
+					remote-endpoint = <&panel_input>;
+				};
+			};
+		};
+
+		hlcdc_pwm: hlcdc-pwm {
+			compatible = "atmel,hlcdc-pwm";
+			pinctrl-names = "default";
+			pinctrl-0 = <&pinctrl_lcd_pwm>;
+			#pwm-cells = <3>;
+		};
+	};
+
+Example 2: With a video interface override to force rgb565; as above
+but with these changes/additions:
+
+	&hlcdc {
+		hlcdc-display-controller {
+			pinctrl-names = "default";
+			pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb565>;
+
+			port@0 {
+				hlcdc_panel_output: endpoint@0 {
+					bus-width = <16>;
+				};
+			};
+		};
+	};
