[PATCH v3 2/5] drm/bridge: synopsys: Add DW HDMI QP TX Controller support library

Cristian Ciocaltea
2024-08-07T11:08:45Z

The Synopsys DesignWare HDMI 2.1 Quad-Pixel (QP) TX Controller IP
supports the following features, among others:

* Fixed Rate Link (FRL)
* Display Stream Compression (DSC)
* 4K@120Hz and 8K@60Hz video modes
* Variable Refresh Rate (VRR) including Quick Media Switching (QMS), aka
Cinema VRR
* Fast Vactive (FVA), aka Quick Frame Transport (QFT)
* SCDC I2C DDC access
* TMDS Scrambler enabling 2160p@60Hz with RGB/YCbCr4:4:4
* YCbCr4:2:0 enabling 2160p@60Hz at lower HDMI link speeds
* Multi-stream audio
* Enhanced Audio Return Channel (EARC)

Add library containing common helpers to enable basic support, i.e. RGB
output up to 4K@60Hz, without audio, CEC or any HDMI 2.1 specific
features.
