Hello everyone,
This patchset adds support for the UGEE XP-PEN Deco L tablet.
This device belongs to a family of tablets that must receive a chunk of
magic data in order to be enabled (named UGEE v2 internally).
Once the device is enabled, its parameters can be discovered by parsing
a report descriptor. HUION v1 tablets have a similar report descriptor
but, in the case of UGEE v2 tablets, the number of buttons are also
discoverable [1].
The ability to discover the number of buttons is the reason for the
first 3 patches. They enable frame templates.
Because I lack the hardware to fully test this driver, I added some
KUnit tests to make sure no bugs are introduced.
I didn't see any other test in the subsystem (and I doubt I'm the first
person writing one) so please let me know if I need to move the test to
a different place.
The last patch enables the tablet and it should give Stefan a stable
code to work on his XP-PEN Deco Mini 7 tablet.
Stefan: I didn't include the code for the Mini 4 because once connected
no events are received until I unload and load the driver.
If anyone has a clue about why this could happen, I'd really appreciate
some help. [2]
Best wishes,
José Expósito
[1] I don't own a HUION v1 device, so I'm not sure if the information
about the number of buttons is also present and it is not used in
the driver for some reason.

In order to differentiate UGEE tablets that need this kind of initialization from the previous ones, name them v2 internally and create an entry point for them. After initialization, the template report descriptors can be discovered by parsing a string descriptor, similar to the one exposed by HUION v1 devices.
