This adds a driver for the Pegasus Notetaker Pen. When connected,
this uses the Pen as an input tablet.
This device was sold in various different brandings, for example
"Pegasus Mobile Notetaker M210",
"Genie e-note The Notetaker",
"Staedtler Digital ballpoint pen 990 01",
"IRISnotes Express" or
"NEWLink Digital Note Taker".
Here's an example, so that you know what we are talking about:
http://www.genie-online.de/genie-e-note-2/
https://pegatech.blogspot.com/ seems to be a remaining official resource.
This device can also transfer saved (offline recorded handwritten) data and
there are userspace programs that do this, see https://launchpad.net/m210
(Well, alternatively there are really fast scanners out there :)
It's *really* fun to use as an input tablet though! So let's support this
for everybody.

For devices that are incapable of reporting per-contact distance and can
only report ABS_DISTANCE, just distance is not enough for upper layers of
OS to determine whether contact is leaving the area or if it is continuing
hovering, we need BTN_TOOL_FINGER for that:
Contact State
Inactive Hovering Active
(far away) (inside hover area) (touching surface)
BTN_TOUCH 0 0 1
BTN_TOOL_FINGER 0 1 1
ABS_DISTANCE N/A 1 0

We should not be ignoring -EPROBE_DEFER reported by
devm_gpiod_get_optional(), but report it as any other error to the upper
layers. While we are at it simplify check for the presence of reset GPIO
and instead of using IS_ERR_OR_NULL just use boolean.
Also do not return -ENOMEM from suspend handler when the device in
bootloader mode as that does not make sense and switch to -EBUSY instead.

This change creates a second input device which will handle input from
a Surface Pen. The Surface Pen supplies a different packet header than
touch events, so it is simple to handle one or the other.
This patch handles both the newer Surface Pen with one button, and the
older variant with a second button to switch to Eraser mode.

This is a basic driver for the Surface 3. I am not so sure it will work
with any firmwares as most values are encoded, but given that I only have
access to my current device with its firmware and I don't have the
datasheet, it should be OK for now.
The Surface Pen is not supported (if it is supposed to be). I'll work on
this when I get one.

Commit 4369c64c79a22 ("Input: Send events one packet at a time")
significantly reduced amount of entropy input core was feeding to the rest
of the system, because only the very first event in the event block would
be used as source of entropy.
With this change we will be calling add_input_randomness() for every event
that is not filtered by the input core as a duplicate. In addition, all
EV_SYN events are ignored.

The migor touchscreen driver is now available for COMPILE_TEST,
so we run into a harmless randconfig warning on ARM when CONFIG_PM
is disabled:
drivers/input/touchscreen/migor_ts.c:216:12: error: 'migor_ts_resume' defined but not used [-Werror=unused-function]
drivers/input/touchscreen/migor_ts.c:205:12: error: 'migor_ts_suspend' defined but not used [-Werror=unused-function]
This shuts up the warning by marking the two functions as __maybe_unused.
We could do the same thing by adding an #ifdef, but this version is
more reliable.

The driver only has runtime but no build time dependency with SH_MIGOR, so
it can be built for testing purposes if the COMPILE_TEST option is enabled.
This is useful to have more build coverage and make sure that drivers are
not affected by changes that could cause build regressions.

The CM109 driver reported key press events of volume up / down and
record / playback mute buttons, but no release events. Report those events
properly by handling volume and mute keys seperately. For the record and
playback mute buttons, only presses are registered by the CM109, therefore
simulate press-n-release. This fixes the volume control buttons of various
USB headsets.

The bitwise shift operator has lower priority than plus operator. So the
values on macros should be enclosed in parentheses.

Instead of doing the dance with macro that either resolves to a pointer or
NULL, let's switch to using SIMPLE_DEV_PM_OPS().
Also let's mark suspend and resume methods as __maybe_unused instead of
guarding them with an #ifdef and rely on linker to drop unused code. Doing
so should allow better compile coverage.

This patch enables this during normal operation, and combines the
