[PATCH v2 0/2] arm64: dts: qcom: msm8939-asus-z00t: add initial device tree

[Erikas Bitovtas]

This dts adds support for Asus ZenFone 2 Laser/Selfie (1080p) smartphone released in 2015.

Add an initial device tree support for Z00T with support for:
- GPIO keys 
- SDHCI (Internal and external storage)
- WCNSS (WiFi/BT)
- Sensors (accelerometer and magnetometer)
- Touchscreen 
- Audio input and output
- Vibrator
---
Changes in v2:
- added customary newline before 'status' properties
- removed odd newlines in pin configuration nodes
- reordered pin configuration nodes by their 'pins' properties

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
of patchset, under or above your Signed-off-by tag, unless patch changed
significantly (e.g. new properties added to the DT bindings). 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.

Please read:
https://elixir.bootlin.com/linux/v6.12-rc3/source/Documentation/process/submitting-patches.rst#L577

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
of patchset, under or above your Signed-off-by tag, unless patch changed
significantly (e.g. new properties added to the DT bindings). 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.

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


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: remotes/arm-soc/qcom/dt64-51-gc11645afb0e2 (best guess, 1/2 blobs matched)
 Base: remotes/arm-soc/qcom/dt64-51-gc11645afb0e2 (use --merge-base to override)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
