2012-09-19HID: hid-multitouch: Simplify setup and frame synchronizationHenrik Rydberg
With the input_configured() callback in place, the setup and frame synchronization can be simplified. The input device initialization is moved to mt_input_configured(), to make sure the full HID report has been seen.

2012-06-28HID: hid-multitouch: fix input mode feature commandBenjamin Tissoires
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. Signed-off-by: Benjamin Tissoires <benjamin.tissoires@enac.fr> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

2012-05-10HID: hid-multitouch: fix wrong protocol detectionBenjamin Tissoires
The previous implementation introduced a randomness in the splitting of the different touches reported by the device.

2012-05-05HID: hid-multitouch: Only match MT interfacesHenrik Rydberg
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.

2012-05-01HID: hid-multitouch: Switch to device groupsHenrik Rydberg
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.

2012-03-20HID: multitouch: add PID for Fructel productAndreas Nielsen
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 the only way for us to support Android games that doesn't support HID gamepads.

2012-03-12HID: handle all multitouch devices through hid-multitouchBenjamin Tissoires
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 not been registered in hid-multitouch. 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.

2012-02-06HID: multitouch: support Perixx PERIPAD 701Benjamin Tissoires
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.

2012-02-06HID: multitouch: add control of the feature "Maximum Contact Number"Benjamin Tissoires
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.

This reverts commit 0db3bfc72adf0c (""HID: multitouch: decide if hid-multitouch needs to handle mt devices"). The generic detection of hid-mt devices has two major flaws, and was merged prematurely. Firstly, the hid-multitouch gets loaded even when the device is handled by a special device. Secondly, the patch only partially duplicates the device whitelist already present in hid-core, effectively rendering a number of devices non-functional.

Now that hid-generic ignores all win7 compatible multitouch devices, this patch allows hid-multitouch to catch them.
