When a finger is lifted from a Synaptics touchpad the firmware will continue
to interrupts for up to a second. These additional interrupts are know and
dribble interrupts. Since the data read from the touchpad does not change
the input subsystem only reports a single event. This makes the servicing of
dribble interrupts on Linux unnecessary. This patch simply disables dribble
interupts when configuring the touchpad.

The HID over I2C specification allows to have the interrupt for a HID
device to be GPIO instead of directly connected to the IO-APIC.
Add support for this so that when the driver does not find proper interrupt
number from the I2C client structure we check if it has ACPI GpioInt()
resource listed in _CRS. If it is found we convert it to an interrupt
number and use it instead.

This commit exposes in sysfs the HID country code that is stored in the country
member of hid_device structure. It identifies the country code of localized
hardware.
For example some keyboards use it to exhibit the language of the key layout. It
helps the upper layer to identify the localized hardware and setup the correct
language to use.
For USB HID devices the country code comes for the HID descriptor and for
Bluetooth HID devices it is the HIDCountryCode attribute from the SDP database.

Section 4.2.5 of HID Sensor hub specification allows two methods
defining sensor devices.
- Each sensor device by its own collection
- A top level application collection object, including multiple
sensors.
In the first method, each sensor can be in its own sensor application
collection without a physical collection.
In the second method there is a usage id for collection type, which
is defined as an application collection, with multiple physical
collections in it. It is possible to define fusion sensor with this
and may have its own handler. If there is a callback registered
for the collection type, then forward all reports for sensors in
its collection to this handler.

Current implementation only allows one outstanding synchronous read.
This is a performance hit when user mode is requesting raw reads
of sensor attributes on multiple sensors together.
This change changes the mutex lock to per hid sensor hub device instead
of global lock. Although request to hid sensor hub is serialized, there
can be multiple outstanding read requests pending for responses via
hid reports.

d1c7e29e8d27 (HID: i2c-hid: prevent buffer overflow in early IRQ)
changed hid_get_input() to read ihid->bufsize bytes, which can be
more than wMaxInputLength. This is the case with the Dell XPS 13
9343, and it is causing events to be missed. In some cases the
missed events are releases, which can cause the cursor to jump or
freeze, among other problems. Limit the number of bytes read to
min(wMaxInputLength, ihid->bufsize) to prevent such problems.

Identify Logitech gaming wheels in compatibility modes accordingly to Logitech
specifications.
Logitech specification contains a general method of identifying various
models of their gaming wheels while they are in "compatibility" mode.
This patch implements the method instead of checking against known
values of bcdDevice. Handling of the mode switch upon initialization is
also adjusted so that the driver does not have to go through the entire
initialization routine because the wheels are set to perform a USB
detach before they reappear in "native" mode.

The Microsoft HID over I2C specification says two things regarding the
interrupt:
1) The interrupt should be level sensitive
2) The device keeps the interrupt asserted as long as it has more reports
available.
We've seen that at least some Atmel and N-Trig panels keep the line low as
long as they have something to send. The current version of the driver only
detects the first edge but then fails to read rest of the reports (as the
line is still asserted).
Make the driver follow the specification and configure the HID interrupt to
be level sensitive.
The Windows HID over I2C driver also seems to do the same.

The FF2 driver (usbhid/hid-pidff.c) sends commands to the stick during ff_init.
However, this is called inside a block where driver_input_lock is locked, so
the results of these initial commands are discarded. This behavior is the
"killer", without this nothing else works.
ff_init issues commands using "hid_hw_request". This eventually goes to
hid_input_report, which returns -EBUSY because driver_input_lock is locked. The
change is to delay the ff_init call in hid-core.c until after this lock has
been released.
Calling hid_device_io_start() releases the lock so the device can be
configured. We also need to call hid_device_io_stop() on exit for the lock to
remain locked while ending the init of the drivers.

It appears that the Cintiq Companion Hybrid does not send an ABS_MISC event to
userspace when any of its ExpressKeys are pressed. This is not strictly
necessary now that the pad exists on its own device, but should be fixed for
consistency's sake.
Traditionally both the stylus and pad shared the same device node, and
xf86-input-wacom would use ABS_MISC for disambiguation. Not sending this causes
the Hybrid to behave incorrectly with xf86-input-wacom beginning with its
8f44f3 commit.

If a disconnect occurs while getting the actual name of the device
(which can take several HID transactions), the name of the device will
be the hid name, provided by the Unifying Receiver.
This means that in some cases, the user space will see a different
name that what it usually sees when there is no disconnect.
We should store the name of the device in the struct hidpp. That way,
if a disconnect occurs while we are accessing the name,
hidpp_connect_event() can fail, and the input node is not created.
The input node will be created only if we have a connection which
lasts long enough to retrieve all the requested information:
name, protocol, and specific configuration.
