[PATCH RESEND] arm64: dts: ti: k3-am62-main: Add gpio-ranges properties

[Ronald Wahl]

From: Ronald Wahl <ronald.wahl@raritan.com>

On the AM62 platform we have no single 1:1 relation regarding index of
gpio and pin controller. Actually there are some linear ranges with
small holes inbetween. These ranges can be represented with the
gpio-ranges device tree property. They have been extracted manually
from the AM62x datasheet (Table 6-1. Pin Attributes).

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

[1/1] arm64: dts: ti: k3-am62-main: Add gpio-ranges properties
      commit: ba78573abba7eb20190b2bb55e5cb5b55a8854fc

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.
