[PATCH v3 1/2] arm64: dts: ti: k3-am62a-main: Fix main padcfg length

[Paresh Bhagat]

From: Vibhore Vardhan <vibhore@ti.com>

The main pad configuration register region starts with the register
MAIN_PADCFG_CTRL_MMR_CFG0_PADCONFIG0 with address 0x000f4000 and ends
with the MAIN_PADCFG_CTRL_MMR_CFG0_PADCONFIG150 register with address
0x000f4258, as a result of which, total size of the region is 0x25c
instead of 0x2ac.

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

[1/2] arm64: dts: ti: k3-am62a-main: Fix main padcfg length
      commit: 4c4e48afb6d85c1a8f9fdbae1fdf17ceef4a6f5b
[2/2] arm64: dts: ti: k3-am62d2-evm: Enable USB support
      commit: 5cd40f33273bb41b5eec763bcfc7c9b2e9fe2e64

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.
