+TPO TPG110 Panel
+================
+
+This binding builds on the DPI bindings, adding a few properties
+as a superset of a DPI. See panel-dpi.txt for the required DPI
+bindings.
+
+Required properties:
+- compatible : "tpo,tpg110"
+- grestb-gpios : panel reset GPIO
+- scen-gpios : serial control enable GPIO
+- scl-gpios : serial control clock line GPIO
+- sda-gpios : serial control data line GPIO
+
+Required nodes:
+- Video port for DPI input, see panel-dpi.txt
+- Panel timing for DPI setup, see panel-dpi.txt
+
+Example
