[PATCH 0/8] arm64: dts: ti: k3-j784s4/am69: Add uart, i2c, eeprom, misc

[Nishanth Menon]

Hi,

This series picks up from where [1] left off. After fixing the mux
regions, introduce the basic i2c, uarts, ethernet, and a few alias
fixups sprinkled along with it.

This series also takes over [2] and rebased on top of [1] and my series.

Test log: 

Dasnavis Sabiya (1):

[8/8] arm64: dts: ti: k3-am69-sk: Add pinmux for RPi Header
      commit: 0ec1a48d99ddd11c265f7f1b2573fb2c8e0db0ab

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.
