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!

I have applied the following to branch ti-k3-dts-next on [1]:

[1/6] arm64: dts: ti: k3-am62x-sk-common: Update main-i2c1 frequency
      commit: 73387da70f9c26b6fba4f62371d013cce14663d9
[2/6] arm64: dts: ti: k3-am62-main: Add node for DSS

[3/6] arm64: dts: ti: k3-am62x-sk-common: Add HDMI support
      commit: db6e8237cf5435e972ea47632e5d8ac3e356f210

[5/6] arm64: dts: ti: k3-am625-beagleplay: Add HDMI support
      commit: 1f7226a5e52cb8b90771cefc29077f9ce13a3c90

I have applied the following to branch ti-k3-config-next on [1]:

[6/6] arm64: defconfig: Enable ITE_IT66121 HDMI transmitter
      commit: d5c988b43746de250bed33c17116e879f032ff12

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.
