+title: Allwinner A83t DWC HDMI TX Encoder
+
+description: |
+  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 bridge/synopsys,dw-hdmi.yaml with the following device-specific
+  properties.
