This adds the drums and guitar extensions for Wiimote devices.
Devices are reported as "Nintendo Wii Remote Guitar/Drums". If I ever

This is a rebase of the original commits 8e22ecb603 and 73f8645db1.
They were reverted several years ago, since they were dependent on the
ABS_* rework of the input core. Sadly, this never worked out so these
commits were never pushed into a release. This rebase now uses the
ABS_HAT* event codes to report all pressure information.

GEN10 and earlier devices seem to not support DRM_KAI if we run in basic
IR mode. Use DRM_KAIE instead. This might increases overhead slightly as
the extension port is read and streamed but we stream accelerometer data
constantly, too, so this is negligible.
Note that our parsers are hardcoded on IR-formats, so we cannot actually
use 96-bit IR DRMs for basic IR data. We would have to adjust the parsers.
But as only GEN20 and newer support this, we simply avoid mixed DRMs.
This fixes a bug where GEN10 devices didn't provide IR data if
accelerometer and IR are enabled simultaneously. As a workaround, you can
enable DRM_KAIE without this patch via (disables device power-management):

The Wii U Pro Controller is a new Nintendo remote device that looks very
similar to the XBox controller. It has nearly the same features and uses
the same protocol as the Wii Remote.
We add a new wiimote extension device so the Pro Controller is properly
detected and supported.
The device reports MP support, which is odd and I couldn't get it working,
yet. Hence, we disable MP registers for now. Further investigation is
needed to see what extra capabilities are provided.
There are some other unknown bits in the extension reports that I couldn't
figure out what they do. You can use hidraw to access these if you're
interested.
We might want to hook up the "charging" and "USB" bits to the battery
device so user-space can query whether it is currently charged via USB.

If an extension device isn't initialized properly, or during hardware
initialization, a device might send extension data which is all 0xff.
This is ambigious because this is also a valid normal data report. But
it is impossible, under normal conditions, to trigger valid reports with
all 0xff. Hence, we can safely ignore them.

We normally get EXT hotplug events or poll for MP hotplugging so we
don't need to force extension port initialization during device setup.
But for gen20 devices, we disable MP polling because MP is always
present. However, this prevents MP initialization during device setup
and users need to plug another extension to trigger EXT/MP detection.
Therefore, we now trigger EXT/MP detection during device setup
automatically. This also avoids slightly delayed extension detection
and provides sysfs child-devices prior to the "changed"-uevent during
device setup.

The Wii Remote has several extension ports. The first port (EXT) provides
hotplug events whenever an extension is plugged. The second port (MP)
does not provide hotplug events by default. Instead, we have to map MP
into EXT to get events for it.
This patch introduces hotplug support for extensions. It is fairly
complicated to get this right because the Wii Remote sends a lot of
noise-hotplug events while activating extension ports. We need to filter
the events and only handle the events that are real hotplug events.
Mapping MP into EXT is easy. But if we want both, MP _and_ EXT at the same
time, we need to map MP into EXT and enable a passthrough-mode. This will
then send real EXT events through the mapped MP interleaved with real MP
events. But once MP is mapped, we no longer have access to the real EXT
registers so we need to perform setup _before_ mapping MP. Furthermore, we
no longer can read EXT IDs so we cannot verify if EXT is still the same
extension that we expect it to be.
We deal with this by unmapping MP whenever we got into a situation where
EXT might have changed. We then re-read EXT and MP and remap everything.
The real Wii Console takes a fairly easy approach: It simply reconnects to
the device on hotplug events that it didn't expect. So if a program wants
MP events, but MP is disconnected, it fails and reconnects so it can wait
for MP hotplug events again.
This simplifies hotplugging a lot because we just react on PLUG events and
ignore UNPLUG events.
The more sophisticated Wii applications avoid reconnection (well, they
still reconnect during many weird events, but at least not during UNPLUG)
but they start polling the device. This allows them to disable the device,
poll for the extension ports to settle and then initialize them again.
Unfortunately, this approach fails whenever an extension is replugged
while it is initialized. We would loose UNPLUG events and polling the
device later will give unreliable results because the extension port might
be in some weird state, even though it's actually unplugged.
Our approach is a real HOTPLUG approch. We keep track of the EXT and
mapped MP hotplug events whenever they occur. We then re-evaluate the
device state and initialize any possible new extension or deinitialize any
gone extension. Only during initialization, we set an extension port
ACTIVE. However, during an unplug event we mark them as INACTIVE. This
guarantess that a fast UNPLUG -> PLUG event sequence doesn't keep them
marked as PLUGGED+ACTIVE but only PLUGGED.
To deal with annoying noise-hotplug events during extension mapping, we
simply rescan the device before performing any mapping. This allows us to
ignore all the noise events as long as the device is in the correct state.
Long story short: EXT and MP registers are sparsely known and we need to
jump through hoops to get reliable HOTPLUG working. But while Nintendo
needs *FOUR* Bluetooth reconnections for the shortest imaginable
boot->menu->game->menu->shutdown sequence, we now need *ZERO*.
As always, 3rd party devices tend to break whenever we behave differently
than the original Wii. So there are also devices which _expect_ a
disconnect after UNPLUG. Obviously, these devices won't benefit from this
patch. But all official devices were tested extensively and work great
during any hotplug sequence. Yay!

To avoid loading all sub-device drivers for every Wii Remote, even though

The module layer specifies which sub-devices are available on each
device-type. After device detection, we only load the modules for the
detected device. If module loading fails, we unload everything and mark
the device as WIIMOTE_DEV_UNKNOWN. As long as a device is marked as
"unknown", no sub-devices will be used and the device is considered
unsupported.
All the different sub-devices, including KEYS, RUMBLE, BATTERY, LEDS,

Our output queue is asynchronous but synchronous reports may wait for a

output report couldn't be sent. But keep the report ID intact so we don't
incorrectly assume our request succeeded.
Note that the underlying connection is required to be reliable and does
retransmission itself. So it is safe to assume that if the transmission
fails, the device is in inconsistent state. Hence, we abort every request
if any output report fails. No need to verify which report failed.

Battery reports are sent along every status report of the Wii Remote.
So chances are pretty high that we have an up-to-date battery
cache at any time. Therefore, initialize the battery-cache to 100% and
then return battery values from the cache if the query fails.
This works around a power_supply limitation in that it requires us to be
able to query the device during power_supply registration and
removal. Otherwise, "add" or "remove" udev events are not sent. If
we answer these requests from our cache instead, we avoid dropping these
events and no longer cause warnings printed.

Nintendo produced many different devices that are internally based on the
Wii Remote protocol but provide different peripherals. To support these
devices, we need to schedule a device detection during initialization.
Device detection includes requesting a status report, reading extension
information and then evaluating which device we may be dealing with.
We currently detect gen1 and gen2 Wii Remote devices. All other devices
are marked as generic devices. More detections will be added later.
In followup patches we will be using these device IDs to control which
peripherals to initialize. For instance if a device is known to have no IR
camera, there is no need to provide the IR input device nor trying to
access IR registers. In fact, there are 3rd party devices that break if we
try things like this (hurray!).
The init_worker will be scheduled whenever we get hotplug events. This
isn't implemented, yet and will be added later. However, we need to make
sure that this worker can be called multiple times.

The wiimote supports several extensions. This adds a separate source file which
handles all extensions and can be disabled at compile-time.
The driver reacts on "plug"-events on the extension port and starts a worker
which initializes or deinitializes the extensions.
Currently, the initialization logic is not fully understood and we can only
detect and enable all extensions when all extensions are deactivated. Therefore,
we need to disable all extensions, then detect and activate them again to react
on "plug"-events.
However, deactivating extensions will generate a new "plug"-event and we will
never leave that loop. Hence, we only support extensions if they are plugged
before the wiimote is connected (or before the ext-input device is opened). In
the future we may support full extension hotplug support, but
reverse-engineering this may take a while.
