Hi Vignesh/Nishanth,

Please include this in -rc cycle. This should get rid of below
messages since v6.9-rc1

[    0.583305] dwc3-am62 f910000.dwc3-usb: invalid resource (null)
[    0.589304] dwc3-am62 f910000.dwc3-usb: can't map PHY IOMEM resource. Won't apply i2409 fix.

cheers,
-roger

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

[1/1] arm64: dts: ti: k3-am62*: Add PHY2 region to USB wrapper node
      commit: d4fbe9bfc7a110c6700be7fc1484c3ea22b6401d

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.
