4aceed37e3 HID: hid-multitouch: fix input mode feature command
Zytronic panels shows a new way of setting the Input Mode feature.
This feature is put in the second usage in the HID feature, instead
of the first, as the majority of the multitouch devices.

This patch adds a detection step when the feature is presented to know
where the feature is located in the report. We can then trigger the right
command to the device. This removes the magic number "0" in the function
mt_set_input_mode.

3ac36d1555 HID: hid-multitouch: fix wrong protocol detection
The previous implementation introduced a randomness in the splitting
of the different touches reported by the device. This version is more
robust as we don't rely on hi->input->absbit, but on our own structure.

This also prepares hid-multitouch to better support Win8 devices.

2c2110e90b HID: hid-multitouch: Only match MT interfaces
All known hid-multitouch devices currently match any device group.
However, some devices present interfaces belonging to different groups,
resulting in a race between the hid-generic and hid-multitouch modules.
This patch narrows the MT device list to match only HID_GROUP_MULTITOUCH,
which solves the problem.

As an exception, the USB_DEVICE_ID_CYPRESS_TRUETOUCH panel is not
modified, in order to suppress the unwanted extra interfaces of the
device.

4fa3a5837b HID: hid-multitouch: Switch to device groups
Switch the driver over to device group handling.  By adding the
HID_GROUP_MULTITOUCH group to hid-core, hid-generic will no longer
match multitouch devices.  By adding the HID_GROUP_MULTITOUCH entry to
the device list, hid-multitouch will match all unknown multitouch
devices, and udev will automatically load the module.

Since HID_QUIRK_MULTITOUCH never gets set, the special quirks handling
can be removed.  Since all HID MT devices have HID_DG_CONTACTID, they
can be removed from the hid_have_special_driver list.

With this patch, the unknown device ids are no longer NULL, so the code
is modified to check for the generic entry instead.

Adds multitouch support for the Gametel Android game controller.

The multitouch events are emulated by the Gametel device. Each physical button
is configured to generate a MT event on a specific coordinate. This seems to be

It is possible to inject MT events at Android level, but this requires root on

When the quirk HID_QUIRK_MULTITOUCH is present and when hid-multitouch
is loaded, let's pass the device to hid-multitouch even if it has

If any other driver wants to take precedence over hid-multitouch,
the usual way of adding it to hid_have_special_driver will work as
the quirk HID_QUIRK_MULTITOUCH won't be set by the generic hid layer.

847672cd14 HID: multitouch: support Perixx PERIPAD 701
Perixx Peripad 701 is an hybrid device which presents a touchpad and
a keyboard on the same surface. The switch between the two is controlled
by a physical switch, and the firmware sends the events on the right
interface (mouse, keyboard or multitouch).
This patch enables the multitouch interface of this device to work.

We need to manually set the device as a trackpad (we cannot infer it
from the reports descriptors as the device works under Windows, a system
that does not allow multitouch touchpad).
We also need to set the hid feature MAX CONTACT NUMBER to 2 or the device
stops sending events once it has been pressed by two touches.

Some devices, like Perixx Peripad 701 do not work if the feature
"Maximum Contact Number" is not set to the right value.
This patch allows hid-multitouch to control this feature.

If the programmer fills the field maxcontacts in the mt_class,
then the driver will set the feature to this value. It is safe
for current drivers as the feature is read/write in the HID norm
and all devices should implement the norm.

b84bd27fe7 HID: hid-multitouch: fix broken eGalax
Since the inclusion of eGalax devices in 2.6.39, I've got some
bug reports for 480d and other devices.
The problem lies in the reports descriptors: eGalax supports both
pen and fingers, and so the reports descriptors contained both.
But hid-multitouch relies on them to detect the last item in each
field to send the multitouch events. In 480d, the last item is not
Y as it should but Pressure. That means that the fields are not
aligned and X,Y are at 0,0 (the other touch coordinates of the report).

With this patch, the detection is made only when the field ContactID
has been detected inside the collection.

There is still a problem with the detections of the range as stylus
and fingers may not have the same min/max, but it's a start.
