[PATCH] arm64: dts: ti: k3-j7200: Remove "#address-cells" property from GPIO DT nodes

[Aswath Govindraju]

GPIO device tree nodes do not have child nodes. Therefore, "#address-cells"
property should not be added.

Looks like address-cells were added by mistake.

Hi Aswath Govindraju,

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

NOTE: I know this adds warnings with W=2 build of dtbs, BUT, just like
xilinx guys[2] and us[33 -> we have already established #address-cells = <0>
make no sense and dtc is still broken as of next-20210528

So, as far as I am concerned, I am going to keep ignoring these kind of
warnings - and "To" Andre as well.. hopefully we can get around to cleaning
this up some day.

Thank you!

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.
