+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";

+* 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
