Hi,
This series cleansup k3-j721e platforms for pinmuxes and aliases.
Provide complete description of uart and i2c instead of piggy-backing on
bootloader configurations, ensure board detection eeproms are defined,
aliases be defined in the board files as well.
Many of these changes were maintained in u-boot tree, and this moves
those orphan changes to the super set definition in kernel.
Sample bootlog: j721e-common-proc-board in idk-gw configuration:

Define the aliases at the board level instead of using generic aliases
at SoC level.

Enable wakeup_i2c and use un-used pinmux. While at it, describe the
board detection eeprom present on the board.

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.
