+Texas Instruments FPD-Link (LVDS) Serializer
+--------------------------------------------
+
+The DS90C185 and DS90C187 are low-power serializers for portable
+battery-powered applications that reduces the size of the RGB
+interface between the host GPU and the display.
+
+Required properties:
+
+- compatible: Should be
+  "ti,ds90c185", "lvds-encoder"  for the TI DS90C185 FPD-Link Serializer
+  "ti,ds90c187", "lvds-encoder"  for the TI DS90C187 FPD-Link Serializer
+
+Optional properties:
+
+- powerdown-gpios: Power down control GPIO (the PDB pin, active-low)
+
+Required nodes:
+
+The devices have two video ports. Their connections are modeled using the OF
+graph bindings specified in Documentation/devicetree/bindings/graph.txt.
+
+- Video port 0 for parallel input
+- Video port 1 for LVDS output
+
+
+Example
