You don't need reg when there's only one.

Otherwise,

+DWC HDMI TX Encoder
+-----------------------------
+
+The HDMI transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
+with Allwinner's own PHY IP. It supports audio and video outputs and CEC.
+
+These DT bindings follow the Synopsys DWC HDMI TX bindings defined in
+Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with the
+following device-specific properties.
+
+Required properties:
+
+  - compatible: value must be one of:
+    * "allwinner,sun8i-h3-dw-hdmi"
+  - reg: two pairs of base address and size of memory-mapped region, first
+    for controller and second for PHY
+    registers.
+  - reg-io-width: See dw_hdmi.txt. Shall be 1.
+  - interrupts: HDMI interrupt number
+  - clocks: phandles to the clocks feeding the HDMI encoder
+    * iahb: the HDMI interface clock
+    * isfr: the HDMI module clock
+    * ddc: the HDMI ddc clock
+  - clock-names: the clock names mentioned above
+  - resets: phandles to the reset controllers driving the encoder
+    * hdmi: the reset line for the HDMI
+    * ddc: the reset line for the DDC
+  - reset-names: the reset names mentioned above
+
+  - ports: A ports node with endpoint definitions as defined in
+    Documentation/devicetree/bindings/media/video-interfaces.txt. The
+    first port should be the input endpoint. The second should be the
+    output, usually to an HDMI connector.
