Hi,
This patch series adds DT nodes for Display SubSystem (DSS) and other
peripherals required to enable the HDMI audio and video on the
AM62A7-SK EVM. An HDMI monitor can be connected to the platform for the
audio-video outputs.
Regards
Aradhya

2.34.1
Add Display SubSystem (DSS) DT node for the AM62A7 SoC.
The DSS supports one each of video pipeline (vid) and video-lite
pipeline (vidl1). The video port 1 (vp1) is tied-off in AM62A SoC, but
the pipeline remains active. The video port 2 (vp2) outputs the DPI
signals. Both the video ports are connected to the pipelines via 2
identical overlay managers (ovr1 and ovr2).

2.34.1
The DSS outputs DPI signals via its second video port (VP2). The DPI
output from DSS is 24 bits (RGB888) and is forwarded to an HDMI
transmitter (SIL9022) on the board.
Add pinmux info for DSS DPI output.
Add DT nodes for SIL9022 HDMI transmitter (TX), and the HDMI connector
on the AM62A7-SK platforms.
Additionally, connect the output of DSS (VP2) with input of the HDMI TX,
and the output of HDMI TX to the input of the HDMI connector.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
