+TPD12S015 HDMI level shifter and ESD protection chip
+====================================================
+
+Required properties:
+- compatible: "ti,tpd12s015"
+
+Optional properties:
+- gpios: CT CP HPD, LS OE and HPD gpios
+
+Required nodes:
+- Video port 0 for HDMI input
+- Video port 1 for HDMI output
+
+Example
+-------
