  7. rk3588: edge: Add new v10 patch for basic HDMI out support

Subject: [PATCH v10 0/3] Add initial support for the Rockchip RK3588 HDMI TX Controller
Date: Wed, 16 Oct 2024 23:06:50 +0300

The Rockchip RK3588 SoC family integrates the Synopsys DesignWare HDMI
2.1 Quad-Pixel (QP) TX controller, which is a new IP block, quite
different from those used in the previous generations of Rockchip SoCs.

The controller 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)
* Fast Vactive (FVA)
* SCDC I2C DDC access
* Multi-stream audio
* Enhanced Audio Return Channel (EARC)

This is the last component that needs to be supported in order to enable
the HDMI output functionality on the RK3588 based SBCs, such as the
RADXA Rock 5B.  The other components are the Video Output Processor
(VOP2) and the Samsung IP based HDMI/eDP TX Combo PHY, for which basic
support has been already made available via [1] and [2], respectively.

Please note this is a reworked version of the original series, which
relied on a commonized dw-hdmi approach.  Since the general consensus
was to handle it as an entirely new IP, I dropped all patches related to
the old dw-hdmi and Rockchip glue code - a few of them might still make
sense as general improvements and will be submitted separately.

It's worth mentioning the HDMI output support is currently limited to
RGB output up to 4K@60Hz, without audio, CEC or any of the HDMI 2.1
specific features.  Moreover, the VOP2 driver is not able to properly
handle all display modes supported by the connected screens, e.g. it
doesn't cope with non-integer refresh rates.

A possible workaround consists of enabling the display controller to
make use of the clock provided by the HDMI PHY PLL.  This is still work
in progress and will be submitted later, as well as the required DTS
updates.

To facilitate testing and experimentation, all HDMI output related
patches, including those part of this series, are available at [3].

So far I could only verify this on the RADXA Rock 5B board.

Thanks,
Cristian
