Hi all,
The patch series adds DT nodes for Display SubSystem (DSS) and other
peripherals required to enable the HDMI audio and video on the AM625 SK,
AM62-LP SK, as well as the AM625 based Beagle-Play platforms. An HDMI
monitor can be connected to the boards for the audio/video outputs.
The series adding the compatible and basic driver support[0] is in the
drm-misc-next and linux-next queues and is expected to be in the
mainline by v6.6-rc1. Patch 5/6 also requires Nishanth Menon's patch[1]
that introduces debounce select mux macros. This patch too is not in
v6.5-rc1 but has been picked up in ti-next[2] and hence, is present in
linux-next.
Patches 4 and 5 have been picked up from TI's vendor tree[3] based off
linux-kernel v6.1.
Regards
Aradhya
Change Log:
V4 -> V5:
- Cosmetic changes as suggested by Jayesh.
- Fixed the mis-represented DSS VP1 clock, and added a
fixed-factor-clock.
V3 -> V4:
- Added "Fixes" tag for patch 1/6.
- Rebased to linux-next.
- Enabled display at board level and disabled at SoC level.
- Dropped OLDI pinmux configuration as OLDI output comes directly from
the SoC and muxing is not required.
- Squashed DSS pinmux patches into their platform specific HDMI
support patches, because it did not make sense to have only one set
of pinmux config separated in a patch.
V2 -> V3:
- Updated the compatible from "ti,am65x-dss" to "ti,am625-dss".
- Peripheral nodes like HDMI TX, HDMI connector are now added to
k3-am62x-sk-common.dtsi instead of k3-am625-sk.dts, in order to
support AM62-LP SK-EVM as well.
- Dropped the HDMI master clock node as it is not connected on the
EVM, and should not have been added in the first place.
- Re-worded and Re-ordered commits.
- Dropped Rahul Ravikumar's R-bs because of the changes.
- Added AM625 based Beagle-Play for HDMI support.
- Added HDMI audio support as well.
V1 -> V2:
- Removed repetitive data in dss_ports

Can you help cleanup the following before we start introducing new oldi
and dss support? I am not sure if these were introduced due to yaml
updates or something pre-existing.

This is a pre-existing issue. Lets not fault Aradhya nor hold back this
series for an issue we caused way back when initially adding AM65 support.
Just to help this along, I've gone and added the fix for these warnings
here[0][1].

I am tempted to plagiarize Lt. Aldo Raine "I want my fixes", but quips
aside, exactly why not picking up patches without fixes is the last
knob I have to force long standing issue resolution :). unfortunate to
need to use it, happy to see it still work.
That said, the patches will have to wait a cycle anyways (cant take
checkpatch warnings with rc1) for the binding to hit 6.6-rc1. In the
meanwhile lets see about getting that fix series merged..

NOTE: This series creates checkpatch warnings against v6.5-rc1 and
complains that it cannot find ti,am625-dss which has been merged in
drm tree for next. This is clean in linux-next for a few weeks now.
Given the number of people who would really like to see it in v6.6-rc1
to keep the display support working in the tree without carried
patches and work on next set of features on display and graphics, and
given the real low risk of this NOT making to linus-master, we are
making an specific exception here for this time around. So, please
keep a watch on drm-next and if for any reason the support is dropped
going to linus's tre in the merge window or before, let this chain
know with appropriate maintainers so that we can take corrective
actions. PS: Thanks Arnd for taking time to give me some private
guidance. Fingers crossed that this will go through smooth.
Thank you!

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.

Nishanth, Vignesh, Arnd,
Thank you for making an exception here, and allowing these patches in!
=)
I will keep an eye on drm-next and will make sure to let you all know if
the AM62 base DSS support patches get dropped for any reason.
