Merge branch 'drm/next/du' of git://linuxtv.org/pinchartl/fbdev into drm-next 

Commit "drm/rcar-du: Use struct videomode in platform data" touches board code
in arch/arm/mach-shmobile. There is, to the best of my knowledge, no risk of
conflict for v3.18. Simon, are you fine with getting those changes merged
through Dave's tree (and could you confirm that no conflict should occur) ?

Simon acked the merge:
Acked-by: Simon Horman <horms+renesas@verge.net.au>

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"
Optional properties:
- psave-gpios: Power save control GPIO
Required nodes:
The ADV7123 has two video ports. Their connections are modeled using the OF
graph bindings specified in Documentation/devicetree/bindings/graph.txt.
- Video port 0 for DPI input
- Video port 1 for VGA output
Example
-------
adv7123: encoder@0 {
compatible = "adi,adv7123";
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
adv7123_in: endpoint@0 {
remote-endpoint = <&dpi_out>;
};
};
port@1 {
reg = <1>;
adv7123_out: endpoint@0 {
remote-endpoint = <&vga_connector_in>;
};
};
};
};

* Renesas R-Car Display Unit (DU)
Required Properties:
- compatible: must be one of the following.
- "renesas,du-r8a7779" for R8A7779 (R-Car H1) compatible DU
- "renesas,du-r8a7790" for R8A7790 (R-Car H2) compatible DU
- "renesas,du-r8a7791" for R8A7791 (R-Car M2) compatible DU
- reg: A list of base address and length of each memory resource, one for
each entry in the reg-names property.
- reg-names: Name of the memory resources. The DU requires one memory
resource for the DU core (named "du") and one memory resource for each
LVDS encoder (named "lvds.x" with "x" being the LVDS controller numerical
index).
- interrupt-parent: phandle of the parent interrupt controller.
- interrupts: Interrupt specifiers for the DU interrupts.
- clocks: A list of phandles + clock-specifier pairs, one for each entry in
the clock-names property.
- clock-names: Name of the clocks. This property is model-dependent.
- R8A7779 uses a single functional clock. The clock doesn't need to be
named.
- R8A7790 and R8A7791 use one functional clock per channel and one clock
per LVDS encoder. The functional clocks must be named "du.x" with "x"
being the channel numerical index. The LVDS clocks must be named
"lvds.x" with "x" being the LVDS encoder numerical index.
Required nodes:
The connections to the DU output video ports are modeled using the OF graph
bindings specified in Documentation/devicetree/bindings/graph.txt.
The following table lists for each supported model the port number
corresponding to each DU output.
Port 0 Port1 Port2

THine Electronics THC63LVDM83D LVDS serializer
----------------------------------------------
The THC63LVDM83D is an LVDS serializer designed to support pixel data
transmission between a host and a flat panel.
Required properties:
- compatible: Should be "thine,thc63lvdm83d"
Optional properties:
- pwdn-gpios: Power down control GPIO
Required nodes:
The THC63LVDM83D has two video ports. Their connections are modeled using the
OFgraph bindings specified in Documentation/devicetree/bindings/graph.txt.
- Video port 0 for CMOS/TTL input
- Video port 1 for LVDS output
Example
-------
lvds_enc: encoder@0 {

VGA Connector
=============
Required properties:
- compatible: "vga-connector"
Optional properties:
- label: a symbolic name for the connector corresponding to a hardware label
- ddc-i2c-bus: phandle to the I2C bus that is connected to VGA DDC
Required nodes:
The VGA connector internal connections are modeled using the OF graph bindings
specified in Documentation/devicetree/bindings/graph.txt.
The VGA connector has a single port that must be connected to a video source
port.
Example
-------
vga0: connector@0 {
compatible = "vga-connector";
label = "vga";
ddc-i2c-bus = <&i2c3>;
port {
vga_connector_in: endpoint {
