+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

+
+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

+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.

+Electronics Standards Association (VESA)
+
+Device compatible with those specifications have been marketed under the
+FPD-Link and FlatLink brands.
+

Bits for undefined preemption levels are RAZ/WI.
+ For historical reasons and to provide ABI compatibility with userspace we

Limitations:
- Priorities are not implemented, and registers are RAZ/WI
- Currently only implemented for KVM_DEV_TYPE_ARM_VGIC_V2.
