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
