2012-11-15HID: multitouch: fix Win 8 protocolBenjamin Tissoires
The Win 8 protocol specify the fact that each valid touch must be reported within a frame until it is released. We can therefore use the always_valid quirk and dismiss reports when we see duplicate contacts ID. We recognize Win8 certified devices from their vendor feature 0xff0000c5 where Microsoft put a signed blob in the report to check if the device passed the certification.

2012-11-15HID: multitouch: move ALWAYS_VALID quirk checkBenjamin Tissoires
Win 8 device specification changed the requirements for the hid usages of the multitouch devices. Now InRange is optional and must be only used when the device supports hovering. This ensures that the quirk ALWAYS_VALID is taken into account and also ensures its precedence over the other VALID* quirks.

2012-11-15HID: multitouch: get maxcontacts also from logical_max valueBenjamin Tissoires
Win8 devices are required to present the feature "Maximum Contact Number". Fortunately all win7 devices I've seen presents this feature. If the current value is 0, then, the driver can get the actual supported contact count by refering to the logical_max. This win8 specification ensures that logical_max may not be above 250. This also allows us to detect when devices like irtouch or stantum reports an obviously wrong value of 255.

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.

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.
