[PATCH v2] arm64: dts: ti: k3-am62a7-sk: Enable dual role support for Type-C port

[Ravi Gunasekaran]

USB0 is interfaced with a Type-C DRP connector and is managed via a
USB PD controller. Add support for the Type-C port with dual data
and power sink role.

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

[1/1] arm64: dts: ti: k3-am62a7-sk: Enable dual role support for Type-C port
      commit: 5a5cf3bdda04fe72440aa837c9451410d62ffa2f

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.
