[PATCH v4 0/3] X1E Dell XPS 9345 support

[PATCH v4 0/3] X1E Dell XPS 9345 support

[Aleksandrs Vinarskis]

Introduce support for the mentioned laptop.

Very similar to other X1E laptops, device tree was derived by analyzing dtsi of
existing models and ACPI tables of this laptop [1]. Most notable difference were
* TZ protected SPI19.
* Keyboard only working after suspend/resume sequence, will do a follow up patch
to i2c-hid.
* Lots of small deviations in LDOs voltages.

Successfully tested with Debian 12 and Gnome. Firmware for GPU/aDSP/cDSP was
extracted from Windows, WiFi firmware from upstream linux-firmware.

Quite a few things alraedy work, details in patches, quite a few still in WIP or
TODOs. Since fixing these may take me a while due to lack of documentation,
sending current progress as its very much usable.

* v3 link: https://lore.kernel.org/all/20240927094544.6966-1-alex.vinarskis@gmail.com/

--------

Changes to V2:
* Fix uart21 missing alias
* Fix redundant mdss_dp3 defines
* Fix touchscreen i2c address
* Update commit description - OLED panel reported working

* Update commit description - add keyboard patches link
* v2 link: https://lore.kernel.org/all/20240921163455.12577-1-alex.vinarskis@gmail.com/

--------

Changes to V1:
* Fix misalignments due to wrong tab/space conversion
* Fix regulator namings
* Fix reasonable warnings from `scripts/checkpatch.pl`
* Restructure all (sub)nodes alphabetically
* v1 link: https://lore.kernel.org/all/20240919170018.13672-1-alex.vinarskis@gmail.com/

[PATCH v4 3/3] arm64: dts: qcom: Add support for X1-based Dell XPS 13 9345

[Aleksandrs Vinarskis]

Initial support for Dell XPS 9345 13" 2024 (Codenamed 'Tributo') based
on X1E80100.

Working:
* Touchpad
* Keyboard (only post suspend&resume, i2c-hid patch required [1])
* Touchscreen
* eDP (low-res IPS, OLED) with brightness control
* NVME
* USB Type-C ports in USB2/USB3 (one orientation)
* WiFi
* GPU/aDSP/cDSP firmware loading (requires binaries from Windows)
* Lid switch
* Sleep/suspend, nothing visibly broken on resume

Not working:
* Speakers (WIP, pin guessing, x4 WSA8845)
* Microphones (WIP, pin guessing, dual array)
* Fingerprint Reader (WIP, USB MP with ptn3222)
* USB as DP/USB3 (WIP, PS8830 based)
* Camera (Likely OV01A10)
* EC over i2c

Should be working, but cannot be tested due to lack of hw:
* higher res IPS panel

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


New warnings running 'make CHECK_DTBS=y qcom/x1e80100-dell-xps13-9345.dtb' for 20241003211139.9296-1-alex.vinarskis@gmail.com:

How do you test bindings? Running static checks in kernel tree is the
same as compiling software and adding tested-by.

I took the whole patchset in when testing it on the actual hardware,
so I gave the tested-by for the whole series as well.
That being said, the binding patch here does indeed not benefit from
any on device testing. Feel free to drop it.

Thanks for taking your time to test this.
For the record, which variant did you test it on (low res
IPS/OLED/high res IPS)?
