2.34.1
TI keystone display subsystem present in AM65, AM62 and AM62A SoC support
two separate register spaces namely "common" and "common1" which can be
used by two separate hosts to program the display controller as described
in respective Technical Reference Manuals [1].
The common1 register space has similar set of configuration registers as
supported in common register space except the global configuration
registers which are exclusive to common region.
This adds binding for "common1" register region too as supported by the
hardware.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[2/4] arm64: dts: ti: Add common1 register space for AM65x SoC

[4/4] arm64: dts: ti: Add common1 register space for AM62A SoC
commit: 0f9eb43f009091501dd0c68232aa6530ba0e0185
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.
