[PATCH v3 0/2] arm64: Add basic support for LG H815

[Alexander Reimelt]

Hello,

Changes in v3:
- use 0x0 consistently
- pad to 8 digits
- drop compatible = "framebuffer" because it's unused
- drop chosen

Thanks again for your time.

v2: https://lore.kernel.org/linux-devicetree/20240530135922.23326-1-alexander.reimelt@posteo.de/

This is a friendly reminder during the review process.

It looks like you received a tag and forgot to add it.

If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.

https://elixir.bootlin.com/linux/v6.5-rc3/source/Documentation/process/submitting-patches.rst#L577

If a tag was not added on purpose, please state why and what changed.
</form letter>

Best regards,
Krzysztof

Hi all,

> International variant of the LG G4 from 2015.

Obviously correct.
Reviewed-by: Petr Vorel <petr.vorel@gmail.com>

Alexander, others have added their tags in previous versions. IMHO generally
it'd be worth if you carry others tags in next versions (when nothing changes).

I now see Krzysztof was faster to write this. Thus I put the tags with links:

I already replied to Krzysztof, but I messed it up and sent it only to him. 
I'm sorry I wasted everyone's time. I didn't fully understand how the system 
behind these tags worked until now. I should have asked earlier, but thanks 
for pointing it out.

Kind regards,

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
