Hello again everyone!

This patch series adds in basic VTM nodes for all of TI's K3 SoCs. As of
right now these do not do much other than add thermal entries into the
sysfs directory and power down the device once it's exceeded a critical
temperature.

Changes from v1:
- Fixed indexing of thermal nodes[0]

Thanks for reviewing!

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

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.
