This add DT support for AM62x LP SK board which has Automotive package
variant of AM62x SoC with LPDDR4 and OSPI NAND
Product link: https://www.ti.com/tool/SK-AM62-LP
Logs: https://gist.github.com/r-vignesh/0ad701f3df614cc5f90b6de775f2584e
Since v1:
Drop wild card 'x' and rename compatible and dts file to am62-lp-sk.dts
as suggested by Krzysztof.

From: Anand Gadiyar <[email protected]>
The AM62x LP SK board is similar to the AM62x SK board, but has some
not-so-minor changes that requires different device tree.
The differences are mainly:
- AM62x SoC in the AMC package that meets AECQ100 automotive standard.
- LPDDR4 versus DDR4 on the AM62x SK.
- TPS65219 PMIC instead of discrete regulators.
- IO expander pin names are wired differently.
- Second ethernet port is currently disabled as the boards do not have
the part physically installed.
- OSPI NAND vs OSPI NOR.
- No WLAN chip instead a SDIO M.2 connector.

From: Anand Gadiyar <[email protected]>
To prepare for upcoming derivative boards based on the AM625 SK,
refactor the dts file for this board into a common dtsi file that the
derivative boards will inherit and retain only those parts that are
different in the current dts file.

I have applied the following to branch ti-k3-dts-next on [1].
Thank you!
[1/3] dt-bindings: arm: ti: k3: Add compatible for AM62x LP SK
commit: 1fb3876129214f397b027eff98c614c0f015ecdf
[2/3] arm64: dts: ti: Refractor AM625 SK dts
commit: ba0b22eaef1d2feda379ce486ca68e365ce4baf1
[3/3] arm64: ti: dts: Add support for AM62x LP SK
commit: d956a851ac3c4e1a0ab8c9ed873281b85be01406
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.
