The XP-PEN Deco Pro S is a UGEE v2 device with a frame with 8 buttons,
a bitmap dial and a mouse. Its pen has 2 buttons, supports tilt and
pressure.
All the pieces to support it are already in place. Add its ID in order
to support the device.
The required Wireshark traces were captured by Jouke Witteveen.
For more information check [1].

The string descriptor returned by UGEE v2 devices contains a byte
indicating the device frame type.
The values discovered so far are:
- 0: Frame with buttons, present in the XP-PEN Deco L.
- 1: Frame with buttons and dial, present in the PARBLO A610 PRO.
- 2: Frame with buttons and a mouse, shaped as a dial + touchpad.
Present in the XP-PEN Deco Pro S.
Parse the frame type and add KUnit tests.

At the moment, the driver only supports UGEE v2 devices that have
buttons in their frames.
In order to support other types of frames in the future, move the code
used to initialize this kind of frames to its own function.

The KUnit documentation [1] suggests allowing build tests as a module.
In addition, it is recommended [2] to use snake case names for
kunit_suite and test cases.
Change the Kconfig entry from bool to tristate and stick to the naming
conventions to avoid style issues with future tests.

The commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ
resource from DT core") stopped IRQ resources being available as
platform resources. This broke the sanity check for the expected
number of resources in the Marvell SATA driver which expected two
resources, the IO memory and the interrupt.
Change the sanity check to only expect the IO memory.

In case push_rcu() and related functions are buggy, there's a
WARN_ON(len >= 128), which the selftest tries to hit by being tricky. In
case it is hit, we shouldn't corrupt the kernel's stack, though;
otherwise it may be hard to even receive the report that it's buggy. So
conditionalize the stack write based on that WARN_ON()'s return value.
Note that this never *actually* happens anyway. The WARN_ON() in the
first place is bounded by IS_ENABLED(DEBUG), and isn't expected to ever
actually hit. This is just a debugging sanity check.
Additionally, hoist the constant 128 into a named enum,
MAX_ALLOWEDIPS_BITS, so that it's clear why this value is chosen.

Using msleep() is problematic because it's compared against
ratelimiter.c's ktime_get_coarse_boottime_ns(), which means on systems
with slow jiffies (such as UML's forced HZ=100), the result is
inaccurate. So switch to using schedule_hrtimeout().
However, hrtimer gives us access only to the traditional posix timers,
and none of the _COARSE variants. So now, rather than being too
imprecise like jiffies, it's too precise.
One solution would be to give it a large "range" value, but this will
still fire early on a loaded system. A better solution is to align the
timeout to the actual coarse timer, and then round up to the nearest
tick, plus change.
So add the timeout to the current coarse time, and then
schedule_hrtimer() until the absolute computed time.
This should hopefully reduce flakes in CI as well. Note that we keep the
retry loop in case the entire function is running behind, because the
test could still be scheduled out, by either the kernel or by the
hypervisor's kernel, in which case restarting the test and hoping to not
be scheduled out still helps.
