Hi Suman Anna,

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

Please note:
* I understand the complexity of the code requiring the split up in the
  incremental patches, so I believe it has a case for us to do the same.
* Special note on MCU R5: there are cases on J721e, J7200 and future devices
  where "device management" functionality will run on MCU R5 core 0, which
  means it is capable of running special firmware that may not respond on
  mailbox at all.. The assumption is that the driver is capable of detecting
  and handling such scenarios and this is a hardware description (as it
  should be).

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.
