HID: hid-multitouch: fix input mode feature command

2012-08-09T15:22:38+00:00

commit 4aceed37e315e8eaa26cb4c8dfd619a32fa24669 upstream.

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.

HID: hid-multitouch: fix wrong protocol detection

2012-05-10T09:35:43+00:00

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.

HID: multitouch: MT interface matching for Baanto

2012-05-05T21:32:54+00:00

Baanto device entry needs to be altered in the same way other device
entries have been changed in 2c2110e90b5 ("HID: hid-multitouch: Only match
MT interfaces").

for Baanto device can be adjusted accordingly to the new autoloading
patches.

HID: hid-multitouch: Only match MT interfaces

2012-05-05T21:27:54+00:00

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.

HID: hid-multitouch: Switch to device groups

2012-05-01T10:54:55+00:00

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.
