+Device-Tree bindings for tilcdc DRM driver
+
+Required properties:
+ - compatible: value should be one of the following:
+    - "ti,am33xx-tilcdc" for AM335x based boards
+    - "ti,da850-tilcdc" for DA850/AM18x/OMAP-L138 based boards
+ - interrupts: the interrupt number
+ - reg: base address and size of the LCDC device
+
+Recommended properties:
+ - ti,hwmods: Name of the hwmod associated to the LCDC
+
+Optional properties:
+ - max-bandwidth: The maximum pixels per second that the memory
+   interface / lcd controller combination can sustain
+ - max-width: The maximum horizontal pixel width supported by
+   the lcd controller.
+ - max-pixelclock: The maximum pixel clock that can be supported
+   by the lcd controller in KHz.
+ - blue-and-red-wiring: Recognized values "straight" or "crossed".
+   This property deals with the LCDC revision 2 (found on AM335x)
+   color errata [1].
+    - "straight" indicates normal wiring that supports RGB565,
+      BGR888, and XBGR8888 color formats.
+    - "crossed" indicates wiring that has blue and red wires
+      crossed. This setup supports BGR565, RGB888 and XRGB8888
+      formats.
+    - If the property is not present or its value is not recognized
+      the legacy mode is assumed. This configuration supports RGB565,
+      RGB888 and XRGB8888 formats. However, depending on wiring, the red
+      and blue colors are swapped in either 16 or 24-bit color modes.
+
+Optional nodes:
+
+ - port/ports: to describe a connection to an external encoder. The
+   binding follows Documentation/devicetree/bindings/graph.txt and
+   supports a single port with a single endpoint.
+
+ - See also Documentation/devicetree/bindings/display/tilcdc/panel.txt and
+   Documentation/devicetree/bindings/display/bridge/ti,tfp410.yaml for connecting
+   tfp410 DVI encoder or lcd panel to lcdc
+
+[1] There is an errata about AM335x color wiring. For 16-bit color mode
+    the wires work as they should (LCD_DATA[0:4] is for Blue[3:7]),
+    but for 24 bit color modes the wiring of blue and red components is
+    crossed and LCD_DATA[0:4] is for Red[3:7] and LCD_DATA[11:15] is
+    for Blue[3-7]. For more details see section 3.1.1 in AM335x
+    Silicon Errata:

+Example:
+
+	fb: fb@4830e000 {
+		compatible = "ti,am33xx-tilcdc", "ti,da850-tilcdc";
+		reg = <0x4830e000 0x1000>;
+		interrupt-parent = <&intc>;
+		interrupts = <36>;
+		ti,hwmods = "lcdc";
+
+		blue-and-red-wiring = "crossed";
+
+		port {
+			lcdc_0: endpoint {
+				remote-endpoint = <&hdmi_0>;
+			};
+		};
+	};
+
+	tda19988: tda19988 {
+		compatible = "nxp,tda998x";
+		reg = <0x70>;
+
+		pinctrl-names = "default", "off";
+		pinctrl-0 = <&nxp_hdmi_bonelt_pins>;
+		pinctrl-1 = <&nxp_hdmi_bonelt_off_pins>;
+
+		port {
+			hdmi_0: endpoint {
+				remote-endpoint = <&lcdc_0>;
+			};
+		};
+	};
