+description: |
+  The Synopsys DesignWare HDMI 2.1 Quad-Pixel (QP) TX Controller IP core
+  supports the following features, among others:
+
+  * Fixed Rate Link (FRL)
+  * Display Stream Compression (DSC)
+  * 4K@...Hz and 8K@...z video modes
+  * Variable Refresh Rate (VRR) including Quick Media Switching (QMS)
+  * Fast Vactive (FVA)
+  * SCDC I2C DDC access
+  * Multi-stream audio
+  * Enhanced Audio Return Channel (EARC)
+
+  Note this is not a full dt-binding specification, but is meant to be
+  referenced by platform-specific bindings for this IP core.
