* Input: wacom - add support for three new ISDv4 sensorsJason Gerecke2014-05-153-1/+41
| | | | | | | | | | | | | | | | | | | | | This patch adds support for the 0x4004, 0x5000, and 0x5002 sensors found on what should be the Motion R12, Fujitsu Q704, and Fujitsu T904. These tablets use a new report ID (3) for their touch packets and a slightly different HID descriptor format, but are otherwise largely identical in protocol to the "MTTPC" tablets. Note: * The R12 uses its 0x4004 sensor for touch input only. A pen interface is not present in its HID descriptor, though its possible a 0x4004 may be used for pen input by other tablet PCs in the future. * The 0x5002 sensor appears to use a new report ID (8) for its pen packets. The other sensors continue to use the traditional report ID (2).

| * Input: wacom - use full 32-bit HID Usage value in switch statementJason Gerecke2014-04-191-128/+109Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A HID Usage is a 32-bit value: an upper 16-bit "page" and a lower 16-bit ID. While the two halves are normally reported seperately, only the combination uniquely idenfifes a particular HID Usage. The existing code performs the comparison in two steps, first performing a switch on the ID and then verifying the page within each case. While this works fine, it is very akward to handle two Usages that share a single ID, such as HID_USAGE_PRESSURE and HID_USAGE_X because the case statement can only have a single identifier. To work around this, we now check the full 32-bit HID Usage directly rather than first checking the ID and then the page. This allows the switch statement to have distinct cases for e.g. HID_USAGE_PRESSURE and HID_USAGE_X.

This packet is sent when the pen is too far away to reliably obtain other information. Because only the location is updated userspace will continue to see stale information for other values, most notably TOUCH, PRESSURE, and DISTANCE. This patch ensures userspace is not left with stale device state information when the pen re-enters proximity (possibly leading to the assumption the pen is still in contact even though it is actually hovering).

Two finger touch devices are processed here since they will not use the updated input_mt_init_slots(), which does not offer benefit to those devices. input_mt_init_slots() will take care of ABS_X/Y assignment when flags are not zero.
