[PATCH v3 2/2] arm64: dts: ti: Add k3-am62-pocketbeagle2

[Robert Nelson]

BeagleBoard.org PocketBeagle 2 is an upgraded version of the popular
PocketBeagle.  It is based on Texas Instruments AM6232 or AM6254 SoC.
Its dual or quad A53 cores can provide higher performance than classic
PocketBeagle. The new design comes with pre-soldered headers, a 3-pin
JST-SH 1.00mm UART debug port, a USB-C port, Texas Instruments
MSPM0L1105 Cortex-M0+ MCU for ADC, 512MB RAM, and a LiPo Battery charger.

MSPM0L1105 firmware source: https://openbeagle.org/pocketbeagle/mspm0-adc-eeprom
* EEPROM 24c32 emulation
* ADC ad7291 emulation

Please drop the autogenerated scripts/get_maintainer.pl CC-entries from
commit msg. There is no single need to store automated output of
get_maintainers.pl in the git log. It can be easily re-created at any
given time, thus its presence in the git history is redundant and
obfuscates the log.

If you need it for your own patch management purposes, keep it under the
--- separator.


Best regards,
Krzysztof

I must say this is a fun little board! Excited to see all the carrier

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

I have dropped the Cc list as Krystoff pointed out this time around when I
applies the patch, but, please take care of this from the next series on.

Thank you!

[1/2] dt-bindings: arm: ti: Add PocketBeagle2
      commit: 3a5ff313ac521ff034f07ea6687ffb3f2229d62a
[2/2] arm64: dts: ti: Add k3-am62-pocketbeagle2
      commit: 92d8c028aa924286f10ac75b7f9e8edfc9ed432b

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.
