Add parser functions for accelerometer data reported by the wiimote. The data is
almost always reported in the same format, so we can use a single handler.
However, an own handler function is created for each DRM-mode because when IR
and extension support is added, each of them is parsed differently.
Also set the appropriate DRM including accelerometer data on DRM requests to
actually retrieve the accelerometer data.
Data is reported to userspace as ABS_RX/Y/Z values. The values are between -500
and 500 and 0 means no acceleration. See also userspace xwiimote library for
data parsing.

Add new input device for every wiimote which is used to report accelerometer
data to userspace. Only if the input device is currently open, we make the
wiimote send accelerometer data. This saves a whole lot of energy on the wiimote
if an application is only interested in button input reports.

The wiimote has a single rumble motor. This adds force feedback support for
wiimote devices with FF_RUMBLE. The rumble motor is very simple and only
supports an on/off switch so no complex ff-effects are supported.
This also removes the event callback that was registered before but unused. The
ff-device overwrites this callback, anyway.

This adds support for the wiimote's rumble device. Every output report can

Now that hid-generic ignores all win7 compatible multitouch devices, this patch
allows hid-multitouch to catch them. The idea is to rely on the quirk
HID_QUIRK_MULTITOUCH to drop the device if no ContactID is given.
There is the need for a blacklist here as other devices may need a special
driver (ntrig for instance).

The IDEACOM 6650 multitouch chip, present in various all-in-one computers,
uses the serial version of the HID multitouch protocol. No existing class

This change fixes two problems.
First, it ensures that the hid-multitouch driver does not incorrectly
map GenericDesktop usages that are intended for other applications,
such as a Mouse.
Second, it sets the appropriate input properties so that user-space
can distinguish TouchScreen devices (INPUT_PROP_DIRECT) from
TouchPad devices (INPUT_PROP_POINTER) and configure them accordingly.

With this driver, all the devices paired to a single Unifying
receiver are exposed to user processes in separated /input/dev
nodes.
Keyboards with different layouts can be treated differently,
Multiplayer games on single PC (like home theater PC) can
differentiate input coming from different kbds paired to the
same receiver.
Up to now, when Logitech Unifying receivers are connected to a
Linux based system, a single keyboard and a single mouse are
presented to the HID Layer, even if the Unifying receiver can
pair up to six compatible devices. The Unifying receiver by default
multiplexes all incoming events (from multiple keyboards/mice)
into these two.

and G27 all use a common command, DFP uses another one. Range can be set from

"/sys/module/hid_logitech/drivers/hid:logitech/<dev>range". The driver use list

This is the first out of five patches me and Simon Wood (CC'd) have been
working on. It separates the handling of Logite from the generic lgff driver
and adds additional features specific for the Logitech wheels, namely
- Native mode support for Driving Force GT, Driving Force Pro, G25 and G27
wheels Every Logitech wheel reports itself as generic Logitech Driving Force
wheel (VID 046d, PID c294). This is done to ensu wheel will work on every USB
HID-aware system even when no Logitech driver is available. It however limits
the capabilit wheel - range is limited to 200 degrees, G25/G27 don't report the
clutch pedal and there is only one combined axis for t brake. The switch to
native mode is done via hardware-specific command which is different for each
wheel. When the wheel receives such command, it simulates reconnect and reports
to the OS with its actual PID.
- Adjustable wheel range DFGT, DFP, G25 and G27 have variable range of the
steering wheel. The range is limited by applying a maximum constant when the
wheel is turned beyond the allowed range. The limit as also set by a
hardware-specific command. There is a comm command for DFGT, G25 and G27 and
another one for DFP. It is probably possible to use the DFP command to limit
the range other Logitech wheels too, but this is not supported by the official
Logitech driver for Windows. The patch adds a sysfs interface which allows for
the range to be set from userspace.
- Fixed autocentering command All Logitech wheels support FF_AUTOCENTER effect.
The original implementation in the lgff driver didn't work well with patch
fixes it. According to USB communication sniffs the Formula Force EX (pretty
much rebranded original Driving Force accept the generic autocentering command,
this issue is also addressed by the patch
There are still some features this patch doesn't cover, but since some of them
will most likely require modifications of memless driver we have decided not to
include them yet.
As first we decided to move the handling of Logitech wheels from hid-lgff
driver to hid-lg4ff driver (originally used fo At also adds PID of Logitech
Driving Force GT.

This is basically a more generic respin of 23746a6 ("HID: magicmouse: ignore
'ivalid report id' while switching modes") which got reverted later by
c3a492.
It turns out that on some configurations, this is actually still the case
and we are not able to detect in runtime.
The device reponds with 'invalid report id' when feature report switching it
into multitouch mode is sent to it.
This has been silently ignored before 0825411ade ("HID: bt: Wait for ACK
on Sent Reports"), but since this commit, it propagates -EIO from the _raw
callback .
So let the driver ignore -EIO as response to 0xd7,0x01 report, as that's
how the device reacts in normal mode.
Sad, but following reality.

HID devices can be hotplugged so we should unregister all sysfs attributes when

power_supply_unregister() must not be called if power_supply_register() failed.
The wdata->psy.dev pointer may point to invalid memory after a failed
power_supply_register() and hence wacom_remove() will fail while calling
power_supply_unregister().
This changes the wacom_probe function to fail if it cannot register the
power_supply devices. If we would want to keep the previous behaviour we had to
keep some flag about the power_supply state and check it on wacom_remove, but
this seems inappropriate here. Hence, we simply fail, too, if
power_supply_register fails.

Patch to add SiGma Micro-based keyboards (1c4f:0002) to hid-quirks.
These keyboards dont seem to allow the records to be initialized, and hence a
timeout occurs when the usbhid driver attempts to initialize them. The patch
just adds the signature for these keyboards to the hid-quirks list with the
setting HID_QUIRK_NO_INIT_REPORTS. This removes the 5-10 second wait for the
timeout to occur.

Add USB device ids for the new revision (MB110LL/B) of Apple's wired aluminum
keyboard. I have only confirmed that the ANSI version is correct - it is
assumed that the ISO and JIS versions follow the standard numbering convention.

The wiimote resets the current drm when an extension is plugged in.
Fortunately, it also sends a status report in this situation so we just
reset the drm on every status report to keep the drm consistent.
Also handle return reports from the wiimote which indicate success and
failure of requests that we've sent.

The wiimote reports data in several data reporting modes (DRM). The DRM
request makes the wiimote send data in the requested drm.
The DRM mode can be set explicitely or can be chosen by the driver. To let
the driver choose the DRM mode, pass WIIPROTO_REQ_NULL placeholder to it. This
is no valid request and is replaced with an appropriate DRM.
Currently, the driver always sets the basic DRM_K mode, but this will be
extended when further peripherals like accelerometer and IR are supported.

This registers 4 led devices to allow controlling the wiimote leds via standard
LED sysfs API. It removes the four sysfs attributes so we don't have two APIs
for one device.

Even though the bluetooth hid backend does not react on open/close callbacks, we
should call them to be consistent with other hid drivers.
Also the new input open/close handlers will be used in future to prepare the
wiimote device for IR/extension input.

The new locking scheme in HID core allows us to remove a bit of synchronization.
Since the HID layer acts synchronously we simply register input core last and
there are no synchonization issues anymore.
Also register sysfs files after that to simplify the code.

Add sysfs files for each led of the wiimote. Writing 1 to the file
enables the led and 0 disables the led.
We do not need memory barriers when checking wdata->ready since we use
a spinlock directly after it.

Save the current state of the leds in the wiimote data structure. This
allows us to discard new led requests that wouldn't change anything.
Protect the whole state structure by a spinlock. Every wiiproto_*
function expects this spinlock to be held when called.

Parse input report 0x30 from the wiimote as button input. We need to
send events for all buttons on every input report because the wiimote
does not send events for single buttons but always for all buttons
to us. The input layer, however, filters redundant events.

The raw hid output function that is supported by bluetooth low-level
hid driver does not provide an output queue and also may sleep. The
wiimote driver, though, may need to send data in atomic context so
this patch adds a buffered output queue for the wiimote driver.
We use the shared workqueue to send our buffer to the hid device.
There is always only one active worker which flushes the whole output
queue to the device. If our queue is full, every further
output is discarded.
Special care is needed in the deinitialization routine. When
wiimote_hid_remove is called, HID input is already disabled, but HID
output may still be used from our worker and is then discarded by the
lower HID layers. Therefore, we can safely disable the input layer since it
is the only layer that still sends input events.
Future sysfs attributes must be freed before unregistering input to
avoid the sysfs handlers to send input events to a non-existing input
layer.
