+Renesas Gen3 DWC HDMI TX Encoder
+================================
+
+The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
+with a companion PHY IP.
+
+These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
+Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
+following device-specific properties.
+
+
+Required properties:
+
+- compatible : Shall contain one or more of
+  - "renesas,r8a7795-hdmi" for R8A7795 (R-Car H3) compatible HDMI TX
+  - "renesas,rcar-gen3-hdmi" for the generic R-Car Gen3 compatible HDMI TX
+
+    When compatible with generic versions, nodes must list the SoC-specific
+    version corresponding to the platform first, followed by the
+    family-specific version.
+
+- reg: See dw_hdmi.txt.
+- interrupts: HDMI interrupt number
+- clocks: See dw_hdmi.txt.
+- clock-names: Shall contain "iahb" and "isfr" as defined in dw_hdmi.txt.
+- ports: See dw_hdmi.txt. The DWC HDMI shall have one port numbered 0
+  corresponding to the video input of the controller and one port numbered 1
+  corresponding to its HDMI output. Each port shall have a single endpoint.
+
+Optional properties:
+
+- power-domains: Shall reference the power domain that contains the DWC HDMI,
+  if any.
+
+
+Example:
+
+	hdmi0: hdmi0@fead0000 {
+		compatible = "renesas,r8a7795-dw-hdmi";
+		reg = <0 0xfead0000 0 0x10000>;
+		interrupts = <0 389 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&cpg CPG_CORE R8A7795_CLK_S0D4>, <&cpg CPG_MOD 729>;
+		clock-names = "iahb", "isfr";
+		power-domains = <&sysc R8A7795_PD_ALWAYS_ON>;
+		status = "disabled";
+
+		ports {
+			#address-cells = <1>;
+			#size-cells = <0>;
+			port@0 {
+				reg = <0>;
+				dw_hdmi0_in: endpoint {
+					remote-endpoint = <&du_out_hdmi0>;
+				};
+			};

+				reg = <1>;
+				rcar_dw_hdmi0_out: endpoint {
+					remote-endpoint = <&hdmi0_con>;
+				};
+			};
+		};
+	};

+		type = "a";
+
+		port {
+			hdmi0_con: endpoint {
+				remote-endpoint = <&rcar_dw_hdmi0_out>;

+Common Properties for Display Panel
+===================================
+
+This document defines device tree properties common to several classes of
+display panels. It doesn't constitue a device tree binding specification by
+itself but is meant to be referenced by device tree bindings.
+
+When referenced from panel device tree bindings the properties defined in this
+document are defined as follows. The panel device tree bindings are
+responsible for defining whether each property is required or optional.
+
+
+Descriptive Properties
+----------------------
+
+- width-mm,
+- height-mm: The width-mm and height-mm specify the width and height of the
+  physical area where images are displayed. These properties are expressed in
+  millimeters and rounded to the closest unit.
+
+- label: The label property specifies a symbolic name for the panel as a
+  string suitable for use by humans. It typically contains a name inscribed on
+  the system (e.g. as an affixed label) or specified in the system's
+  documentation (e.g. in the user's manual).
+
+  If no such name exists, and unless the property is mandatory according to
+  device tree bindings, it shall rather be omitted than constructed of
+  non-descriptive information. For instance an LCD panel in a system that
+  contains a single panel shall not be labelled "LCD" if that name is not
+  inscribed on the system or used in a descriptive fashion in system
+  documentation.
+
+
+Display Timings
+---------------
+
+- panel-timing: Most display panels are restricted to a single resolution and
+  require specific display timings. The panel-timing subnode expresses those
+  timings as specified in the timing subnode section of the display timing
+  bindings defined in
+  Documentation/devicetree/bindings/display/display-timing.txt.
+
+
+Connectivity
+------------
+
+- ports: Panels receive video data through one or multiple connections. While
+  the nature of those connections is specific to the panel type, the
+  connectivity is expressed in a standard fashion using ports as specified in
+  the device graph bindings defined in
+  Documentation/devicetree/bindings/graph.txt.
+
+- ddc-i2c-bus: Some panels expose EDID information through an I2C-compatible
+  bus such as DDC2 or E-DDC. For such panels the ddc-i2c-bus contains a
+  phandle to the system I2C controller connected to that bus.
+
+
+Control I/Os
+------------
+
+Many display panels can be controlled through pins driven by GPIOs. The nature
+and timing of those control signals are device-specific and left for panel
+device tree bindings to specify. The following GPIO specifiers can however be
+used for panels that implement compatible control signals.
+
+- enable-gpios: Specifier for a GPIO connected to the panel enable control
+  signal. The enable signal is active high and enables operation of the panel.
+  This property can also be used for panels implementing an active low power
+  down signal, which is a negated version of the enable signal. Active low
+  enable signals (or active high power down signals) can be supported by
+  inverting the GPIO specifier polarity flag.
+
+  Note that the enable signal control panel operation only and must not be
+  confused with a backlight enable signal.
+
+- reset-gpios: Specifier for a GPIO coonnected to the panel reset control
+  signal. The reset signal is active low and resets the panel internal logic
+  while active. Active high reset signals can be supported by inverting the
+  GPIO specifier polarity flag.
+
+
+Backlight
+---------
+
+Most display panels include a backlight. Some of them also include a backlight
+controller exposed through a control bus such as I2C or DSI. Others expose
+backlight control through GPIO, PWM or other signals connected to an external
+backlight controller.
+
+- backlight: For panels whose backlight is controlled by an external backlight
+  controller, this property contains a phandle that references the controller.

+LVDS Display Panel
+==================
+
+LVDS is a physical layer specification defined in ANSI/TIA/EIA-644-A. Multiple
+incompatible data link layers have been used over time to transmit image data
+to LVDS panels. This bindings supports display panels compatible with the
+following specifications.
+
+[JEIDA] "Digital Interface Standards for Monitor", JEIDA-59-1999, February
+1999 (Version 1.0), Japan Electronic Industry Development Association (JEIDA)
+[LDI] "Open LVDS Display Interface", May 1999 (Version 0.95), National
+Semiconductor
+[VESA] "VESA Notebook Panel Standard", October 2007 (Version 1.0), Video
+Electronics Standards Association (VESA)
+
+Device compatible with those specifications have been marketed under the
+FPD-Link and FlatLink brands.
+
+
+Required properties:
+
+- compatible: Shall contain "panel-lvds" in addition to a mandatory
+  panel-specific compatible string defined in individual panel bindings. The
+  "panel-lvds" value shall never be used on its own.
+- width-mm: See panel-common.txt.
+- height-mm: See panel-common.txt.
+- data-mapping: The color signals mapping order, "jeida-18", "jeida-24"
+  or "vesa-24".
+
+Optional properties:
+
+- label: See panel-common.txt.
+- gpios: See panel-common.txt.
+- backlight: See panel-common.txt.
+- data-mirror: If set, reverse the bit order described in the data mappings
+  below on all data lanes, transmitting bits for slots 6 to 0 instead of
+  0 to 6.
+
+Required nodes:
+
+- panel-timing: See panel-common.txt.
+- ports: See panel-common.txt. These bindings require a single port subnode
+  corresponding to the panel LVDS input.
