2014-05-14Input: wacom - add support for three new ISDv4 sensorsJason Gerecke3-1/+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).

The 0xEC sensor is used in multiple tablet PCs and curiously has versions that report 256 levels of pressure (Samsung Slate 7) as well as versions that report 1024 levels (Lenovo Thinkpad Yoga). To allow both versions to work properly, we allow the value of HID_USAGE_PRESSURE reported to override pressure_max.

2014-04-19Input: wacom - use full 32-bit HID Usage value in switch statementJason Gerecke1-128/+109
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.

There is usb_get_dev() in gtco_probe(), but there is no usb_put_dev() anywhere in the driver. As pointed out by Dmitry Torokhov: The lifetime of gtco structure is already directly tied to lifetime of usb_dev: when destroying usb_dev driver core will call remove() function of currently bound driver (in our case gtco) which will destroy gtco memory.

2013-09-20Input: wacom - send proper tablet state info when pen leaves proximityJason Gerecke1-0/+7
The EMR sensor of Intuos4 and newer devices can send a packet with 0x20 in its second byte which contains only location information. 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).

Henrik added new MT routines in release 3.7. This patch is to prepare for the use of new MT routines. In the newly added wacom_abs_set_axis() function, the first if-statement assigns ABS_X/Y for number of contacts less or equal to 2. So, it is single and 2 finger touch devices. 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. All touch devices with more than two contacts will use input_mt_init_slots() with non-zero flags. The second if-statement is for all MT devices, which include two finger touch devices.
