Initial support for TUXEDO Elite 14 Gen1 laptop. It is based on Qualcomm
Snapdragon X Elite SoC (X1E78100).

Changes in v3:
- add DisplayPort audio to dts
- add el2.dtb to Makefile
- change dts firmware paths
- fix dt-binding (x1e78100 instead of x1e80100)
- improve commit message for elite14gen1 dt-bindings
- remove smb2360_1 from dts (only one USB-C port is present)
- remove "VA MIC BIAS1" from dts
- remove regulator-always-on from vreg_edp_3p3 (display) in dts
- rename vendor prefix of ASL Xiamen Technology to asl-tek
- sort dts

Changes in v2:
- Rebase to v6.18-rc4/master
- Add support for accelerated video decoding
- Add support for audio (speakers, microphones, headset)
- Add support for Bluetooth
- Add support for camera
- Add support for fingerprint reader
- Add support for HDMI-A port
- Add support for QSEECOM
- Add support for USB Type-A
- Add support for USB-C DP altmode
- Add ASL Xiamen Technology Co. Ltd. vendor prefix
- Add TUXEDO vendor prefix
- Add cover letter
- Removal of pointless comments
- Coding style fixes
- Spell check

The device tree uses the dtschema from Linaro DisplayPort PHY patch [1].
ALSA UCM and Audioreach topology patches are available at [2] and [3].
The fingerprint reader requires USB IDs to be patched into libfprint.
WiFi requires a firmware patch [4].

Announcement and request for comments:
Because the SoC is now outdated and some functions still do not work as
well as customers would expect from the TUXEDO brand, TUXEDO Elite 14 Gen1
will not be offered for sale. We would still like to submit our device
tree to the mainline kernel and thus contribute to Linux support for a
compatible device sold by Medion (SPRCHRGD 14 S1 Elite). At least in
Germany, this device was sold in many large stores. (An official press
statement will follow on our website.)

Do you think it would make sense to implement this in a similar way to the
X1E ThinkPad T14s and Thinkpad T14s OLED (with a common dtsi)?

This should be FIRST part of cover letter, so we won't waste time on
reviewing it, instead of burying it deep. Additionally, you should have
named the series RFC.

For me this is unmergeable, because we do not take stuff which no one
uses (no one can even use), and I am sad I put effort in reviewing AFTER
this was known to be cancelled.

I don't think we have any requirement to have a large user base in order
to merge changes. There is already support for plenty of cancelled
products with only a few (if any) remaining users in mainline, e.g.

 - Snapdragon X Elite Dev Kit (x1e001de-devkit), shipped only to a
   handful of users before cancelled
 - All ChromeOS SC7280 devices (including DTB variants for several
   revisions of pre-production samples), never shipped to anyone

There are also plenty of internal reference devices that only a handful
of people have access to (MTP, HDK, CRD etc). What makes these any
different? Ettore has been actively testing and contributing to the port
for the TUXEDO laptop, so if he wants to continue that, I don't think
anything speaks against merging this device tree.

In any case, I don't think the time reviewing these changes is wasted:
As Georg wrote, there is also the Medion SPRCHRGD 14 S1 Elite laptop
that uses basically the same hardware design. I'm sure there are (or
eventually will be) users of that device who would appreciate having a
fully-functional device tree ready to use. There is an open issue in one
of the Ubuntu repositories for example [1] to add automatic DTB
selection for it.

In other words, even if we decide against adding support for the
"x1e80100-tuxedo-elite-14-gen1", the same changes renamed to
"x1e80100-medion-sprchrgd-14-s1" would still be valid and valuable.
I wouldn't expect any other changes to be needed, although obviously
someone with access to the device should confirm that before submitting.

Thanks,
Stephan

I discuss here the timing primarily and I don't know the timing about them.

They are still "maintained" and "offered", even if only for handful
(like 3000 EACH variant) people. That's the amount of board of each
variant, e.g. MTP8750, and all of them run some sort of Linux, even if
downstream. So sorry, but 3000 (or whatever number it is) is not handful.

I won't be maintaining it, so not my effort in that, but since you speak
about that - maintenance is an effort, thus I decide not to spend it on
cancelled products.

I am happy that you do not find my time wasted, but I disagree on that
because knowing this is cancelled, I would probably not care and review
products which are not cancelled at this time.

That's why you send such patches with RFC title and FIRST (literally
first) explanation in cover letter WHY, so people can decide.

You still cannot apply my review to that other board, so still wasted
time because I would need to review again.

Where does 3000 come from? The Bible says 10 people were enough to
maintain Sodom and Gomorrah. For Herobrine we know that there are very
few people still using those devices (maybe less than 10), but we still
keep it. Cheeza was dropped after it was known that the count is exactly
zero.

There still people owning and being happy with those laptops. It's
Bjorn's and Konrad's time being spent on maintaining those. What's the
issue?

I think I described my issue very precise. Please read my first reply in
this thread. Joining discussion at the end of it, not reading it and
then asking "what is the issue" is not really encouraging me to discuss
whether this is a problem or not.

So I said that issue is that I wasted time on reviewing something I
would not review, if this was clearly marked correctly, because I would
consider it waste of time and you asked "what is the issue?"

What sort of question is that? I just wrote what is the issue... And you
ask what issue?

In fact, there are a couple of these TUXEDO devices, some of these are
already being used by people outside the company (by Linaro). There are
also considerations to give the engineering samples to
Linux/ARM-(kernel) enthusiasts.

Do you maintain your position despite the above circumstances?

I understand your frustration, but I'm still learning how to contribute
to the Linux kernel. However, we may be able to find a constructive
solution. Here at TUXEDO, we have the necessary Medion device and have
already adapted the device tree.

Would you review a patch set for Medion SPRCHRGD 14 S1 Elite?

(This device is still on sale and can be found in many large electronics
stores, at least in Germany.)

I think it's worth re-spining this patchset for the Medion SPRCHRGD 14 S1 Elite
with a comment in the DT mentioning the device tree is compatible with
the defunct Tuxedo Elite 14 Gen 1, since the Medion is an actual product
people can buy it's worth it.

I applied to first 3 patches, so you can remove them from the next version.

+1, especially since you mentioned you have an actual Medion at hand

I agree, we can actually try to respin the patches for Medion if
TUXEDO is not worth it.
