Analog Device ADV7123 Video DAC
-------------------------------
The ADV7123 is a digital-to-analog converter that outputs VGA signals from a
parallel video input.
Required properties:
- compatible: Should be "adi,adv7123"

- Video port 1 for VGA output
Example
-------
adv7123: encoder@0 {

display-timing bindings
=======================
display-timings node
--------------------
required properties:
- none
optional properties:
- native-mode: The native mode for the display, in case multiple modes are
provided. When omitted, assume the first node is the native.
timing subnode
--------------
required properties:
- hactive, vactive: display resolution
- hfront-porch, hback-porch, hsync-len: horizontal display timing parameters
in pixels
vfront-porch, vback-porch, vsync-len: vertical display timing parameters in
lines
- clock-frequency: display clock in Hz
optional properties:
- hsync-active: hsync pulse is active low/high/ignored
- vsync-active: vsync pulse is active low/high/ignored
- de-active: data-enable pulse is active low/high/ignored
- pixelclk-active: with
- active high = drive pixel data on rising edge/
sample data on falling edge
- active low = drive pixel data on falling edge/
sample data on rising edge
- ignored = ignored
- interlaced (bool): boolean to enable interlaced mode
- doublescan (bool): boolean to enable doublescan mode
- doubleclk (bool): boolean to enable doubleclock mode
All the optional properties that are not bool follow the following logic:
<1>: high active
<0>: low active
omitted: not used on hardware
There are different ways of describing the capabilities of a display. The
devicetree representation corresponds to the one commonly found in datasheets
for displays. If a display supports multiple signal timings, the native-mode
can be specified.
The parameters are defined as:
+----------+-------------------------------------+----------+-------+

clock-frequency = <52000000>;

hsync-len = <25>;
vback-porch = <2>;
vfront-porch = <2>;
vsync-len = <2>;
hsync-active = <1>;
};
};
Every required property also supports the use of ranges, so the commonly used
datasheet description with minimum, typical and maximum values can be used.
Example:
timing1: timing {

clock-frequency = <148500000>;

vactive = <1080>;

Texas Instruments OMAP Display Subsystem
========================================
Generic Description
-------------------
This document is a generic description of the OMAP Display Subsystem bindings.
Binding details for each OMAP SoC version are described in respective binding
documentation.
The OMAP Display Subsystem (DSS) hardware consists of DSS Core, DISPC module and
a number of encoder modules. All DSS versions contain DSS Core and DISPC, but
the encoder modules vary.
The DSS Core is the parent of the other DSS modules, and manages clock routing,
integration to the SoC, etc.
DISPC is the display controller, which reads pixels from the memory and outputs
a RGB pixel stream to encoders.
The encoder modules encode the received RGB pixel stream to a video output like
HDMI, MIPI DPI, etc.
Video Ports
-----------
The DSS Core and the encoders have video port outputs. The structure of the
video ports is described in Documentation/devicetree/bindings/video/video-
ports.txt, and the properties for the ports and endpoints for each encoder are
described in the SoC's DSS binding documentation.
The video ports are used to describe the connections to external hardware, like
panels or external encoders.
Aliases
-------
The board dts file may define aliases for displays to assign "displayX" style
name for each display. If no aliases are defined, a semi-random number is used
for the display.
Example
-------
