| title: Allwinner A83t DWC HDMI TX Encoder Device Tree Bindings |
| |
| 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 Documentation/devicetree/bindings/display/bridge/dw_hdmi.txt with |
| the following device-specific properties. |
