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>

* 'drm/next/du' of git://linuxtv.org/pinchartl/fbdev:
  drm/rcar-du: Add OF support
  drm/rcar-du: Use struct videomode in platform data
  video: Add DT bindings for the R-Car Display Unit

+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>;

+* 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.
