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.

Annotation
- Immediate include surface: `dt-bindings/interrupt-controller/arm-gic.h`.
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
