+Synopsys DesignWare HDMI TX Encoder
+===================================
+
+This document defines device tree properties for the Synopsys DesignWare HDMI
+TX Encoder (DWC HDMI TX). It doesn't constitue a device tree binding
+specification by itself but is meant to be referenced by platform-specific
+device tree bindings.
+
+When referenced from platform device tree bindings the properties defined in
+this document are defined as follows. The platform device tree bindings are
+responsible for defining whether each property is required or optional.
+
+- reg: Memory mapped base address and length of the DWC HDMI TX registers.
+
+- reg-io-width: Width of the registers specified by the reg property. The
+  value is expressed in bytes and must be equal to 1 or 4 if specified. The
+  register width defaults to 1 if the property is not present.
+
+- interrupts: Reference to the DWC HDMI TX interrupt.
+
+- clocks: References to all the clocks specified in the clock-names property
+  as specified in Documentation/devicetree/bindings/clock/clock-bindings.txt.
+
+- clock-names: The DWC HDMI TX uses the following clocks.
+
+  - "iahb" is the bus clock for either AHB and APB (mandatory).
+  - "isfr" is the internal register configuration clock (mandatory).
+  - "cec" is the HDMI CEC controller main clock (optional).
+
+- ports: The connectivity of the DWC HDMI TX with the rest of the system is
+  expressed in using ports as specified in the device graph bindings defined
+  in Documentation/devicetree/bindings/graph.txt. The numbering of the ports
+  is platform-specific.
