Rev E2 of the AM68 SK baseboard has updated the GPIO IO expander pins
functionality. To match the Rev E2 schematics, update existing IO expander
GPIO line names and the corresponding node which uses the expansion(exp1)
node.

Looking at https://www.ti.com/tool/SK-AM68 looks like E1 never hit
production, is that correct?
Does this need a "Fixes" tag?

Yes, E1 didn't hit production.

It is a migration from E1 to E2 so I assume that a Fixes tag is not required.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[1/1] arm64: dts: ti: k3-am68-sk-base-board: Update IO EXP GPIO lines for Rev E2
commit: 276fa0066b03875f77dba67867d9902361e646fc
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.
