[PATCH 0/3] arm64: dts: ti: k3-am62*-sk: Add wkup/mcu_uart0 aliases

[Markus Schneider-Pargmann]

Hi,

add serial aliases for wkup and mcu uart0. Add them to have the same
order on all boards as well.

Best
Markus

Are'nt these reserved nodes for DM/TIFS and MCU? What purpose does it
serve for us to have an alias in Linux?

For IO+DDR mcu_uart0 can be a wakeup-source and pinctrl needs to be
described for that at some point. So I thought it would be helpful to
have these aliases added already.

I have applied the following to branch ti-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.
