Hello,
These patches add initial support for the LG H815.
They are enough to boot the device on postmarketOS
and have some basic functionality. Connecting to the
device over USB networking via ssh, buttons, SD-Card,
eMMC and regulators work. The dtb_checker shows some
warnings, but they come from the msm8994.dtsi.
For CPU bring up lk2nd is required. The DMA controller
module fails to load and from time to time the SMD clock
driver fails.
But I hope to prevent duplicate work and make it more accessible.
Best regards
Alex

2.44.0
To make it easier for downstream projects and avoid duplication of work.
Makes the device bootable and enables all buttons, most regulators, hall sensor, eMMC and SD-Card.

My bot found new DTB warnings on the .dts files added or changed in this
series.
Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.
If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:
pip3 install dtschema --upgrade

Please use subject prefixes matching the subsystem. You can get them for
example with `git log --oneline -- DIRECTORY_OR_FILE` on the directory
your patch is touching.

That's wrong order. Top level nodes goes after node deletions. Please
observe DTS coding style.

status is the last property.

@Alexander arm: would be for 32bit. Correct subject prefix is:
arm64: dts: qcom: msm8992-lg-h815:
Krzysztof's comments are obviously correct.
Please Cc me on v2 to my gmail private mail. Thanks!
Kind regards,
Petr

I'm not sure if " (International)" shouldn't be dropped.
I guess maintainers will know.
