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

Side note: It would have been useful to state in the diff stat that
gpio_ranges handles the standard GPIO configuration.

[1/1] arm64: dts: ti: k3-j722s-evm: Enable support for mcu_i2c0
      commit: 9442f963098f1eb9d1565fdd694e506d0c2c6f45

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.
