Joshua Jun 05086f3db5 HID: wiimote: Add support for the DJ Hero turntable
This adds support for the turntable extension for Wiimote devices.

jstest-gtk and html5 gamepad tester show everything correctly
but when trying to map the controller in software like rpcs3 or dolphin
it currently doesn't map correctly

Ian Abbott 5eae59cc87 HID: wiimote: narrow spinlock range in wiimote_hid_event()
In `wiimote_hid_event()`, the `wdata->state.lock` spinlock does not need
to be held while searching `handlers[]` for a suitable handler function.
Change it so the spinlock is only held during the call to the handler
function itself.

Daniel G. Morse a8cbf80e9f HID: Wiimote: Treat the d-pad as an analogue stick
The controllers from the Super Nintendo Classic Edition (AKA the SNES
Mini) appear as a Classic Controller Pro when connected to a Wii
Remote. All the buttons work as the same, with the d-pad being mapped
the same as the d-pad on the Classic Controller Pro. This differs from
the behaviour of most controllers with d-pads and no analogue sticks,
where the d-pad maps to ABS_HAT1X for left and right, and ABS_HAT1Y
for up and down. This patch adds an option to the hid-wiimote module
to make the Super Nintendo Classic Controller behave this way.

The patch has been tested with a Super Nintendo Classic Controller
plugged into a Wii Remote in both with the option both enabled and
disabled. When enabled the d-pad acts as the analogue control, and
when disabled it acts as it did before the patch was applied. This
patch has not been tested with e Wii Classic Controller (either the
original or the pro version) as I do not have one of these
controllers.

Although I have not tested it with these controllers, I think it is
likely this patch will also work with the NES Classic Edition
Controllers.

Nicolas Adenis-Lamarre d4bdf2d2ba HID: wiimote: add support for Guitar-Hero devices
This adds the drums and guitar extensions for Wiimote devices.

Devices are reported as "Nintendo Wii Remote Guitar/Drums". If I ever
get my hands on "RockBand" guitars, I will try to report them via the
same interface so user-space does not have to bother which device it
deals with.

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.

Kees Cook e99e88a9d2 treewide: setup_timer() -> timer_setup()
This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.

Casting from unsigned long:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, ptr);

and forced object casts:

    void my_callback(struct something *ptr)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);

become:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

Direct function assignments:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    ptr->my_timer.function = my_callback;

have a temporary cast added, along with converting the args:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;

And finally, callbacks without a data assignment:

    void my_callback(unsigned long data)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, 0);

have their argument renamed to verify they're unused during conversion:

    void my_callback(struct timer_list *unused)
    {
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

The conversion is done with the following Coccinelle script:

spatch --very-quiet --all-includes --include-headers \
	-I ./arch/x86/include -I ./arch/x86/include/generated \
	-I ./include -I ./arch/x86/include/uapi \

  "Input: introduce BTN/ABS bits for drums and guitars"
  "HID: wiimote: add support for Guitar-Hero drums"
  "HID: wiimote: add support for Guitar-Hero guitars"

The extra new ABS_xx values resulted in ABS_MAX no longer being a
power-of-two, which broke the comparison logic.  It also caused the
ioctl numbers to overflow into the next byte, causing problems for that.

We'll try again for 3.13.

David Herrmann 73f8645db1 HID: wiimote: add support for Guitar-Hero drums
Guitar-Hero comes with a drums extension. Use the newly introduced input
drums-bits to report this back to user-space. This is a usual extension
like any other device. Nothing special to take care of.

We report this to user-space as "Nintendo Wii Remote Drums". There are
other drums (like "RockBand" drums) which we currently do not support and

David Herrmann a6be8569b6 HID: wiimote: work around broken DRM_KAI on GEN10
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):
  echo "37" >/sys/kernel/debug/hid/<dev>/drm

David Herrmann b8e0fe31a7 HID: wiimote: support Nintendo Wii U Pro Controller
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.

David Herrmann 77a7480992 HID: wiimote: init EXT/MP during device detection
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.

David Herrmann 4148b6bf8a HID: wiimote: add extension hotplug support
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!

unsupported.

David Herrmann c57ff761be HID: wiimote: add device detection
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.
