wkup_uart0 is a reserved node that is used by Device Manager firmware.
Enabling pinctrl for CTS and RTS breaks the wakeup functionality of
wkup_uart0. Hence they have been dropped.

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

[1/1] arm64: dts: ti: k3-am62p5-sk: Remove CTS/RTS from wkup_uart0 pinctrl
      commit: 0c95ffb74eec3c3d0a5e712984f0c095e58a1021

I did do a minor commit message cleanup to keep it sensible.

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.
