Input: wacom - cleanup multitouch code when touch_max is 2

2014-06-15T07:28:38+00:00

Historically we dealt with touch_max equals to 2 differently from
other MT devices. Now we use input_mt_*() to process all MT events,
as long as touch_max is greater than 1. So, there is no need to
take (touch_max == 2) as a special case any more.

Input: wacom - add support for three new ISDv4 sensors

2014-05-15T01:47:09+00:00

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 - add support for 0x116 sensor on Win8 Panasonic CF-H2

2014-05-14T23:40:07+00:00

The Win8 version of the Panasonic CF-H2 includes a new Wacom device.
The pen interface appears to use the same protocol as before, but the
touch interface has been tweaked to send Win8-compatible reports.

Some tablet PC sensors (e.g. the 0xEC found in the Thinkpad Yoga) report
more than 256 pressure levels and will experience wraparound unless the
full range is read.
