Input: wacom - cleanup multitouch code when touch_max is 2

2014-06-15T07:28:38Z

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. Signed-off-by: Ping Cheng Reviewed-by: Jason Gerecke Signed-off-by: Dmitry Torokhov

Input: wacom - process outbound for newer Cintiqs

2014-05-29T07:09:16Z

New Cintiq tablets have a 200 tablet counts outside of screen area. Add x/y_min for ABS_X/Y to pass this information to userland. Signed-off-by: Ping Cheng Reviewed-by: Jason Gerecke Tested-by: Jason Gerecke Signed-off-by: Dmitry Torokhov

Input: wacom - add support for three new ISDv4 sensors

2014-05-15T01:47:09Z

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). Signed-off-by: Jason Gerecke Reviewed-by: Ping Cheng Signed-off-by: Dmitry Torokhov

Input: wacom - use unaligned access where necessary

2014-05-15T01:47:08Z

A few cases of incorrectly using 'le16_to_cpup' instead of 'get_unaligned_le16' have been noticed and fixed. Signed-off-by: Jason Gerecke Signed-off-by: Dmitry Torokhov

Merge with Linux 3.15-rc5 to sync up Wacom and other changes.

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

2014-05-14T23:40:07Z

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. Signed-off-by: Jason Gerecke Reviewed-by: Ping Cheng Signed-off-by: Dmitry Torokhov

Input: wacom - handle 1024 pressure levels in wacom_tpc_pen

2014-04-19T20:57:35Z

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. Signed-off-by: Jason Gerecke Tested-by: Aaron Skomra Reviewed-by: Carl Worth Signed-off-by: Dmitry Torokhov

Input: wacom - references to 'wacom->data' should use 'unsigned char*'

2014-04-19T20:57:35Z

'wacom->data' contains raw binary data and can lead to unexpected behavior if a byte under examination happens to have its MSB set. Signed-off-by: Jason Gerecke Tested-by: Aaron Skomra Reviewed-by: Carl Worth Signed-off-by: Dmitry Torokhov

Input: wacom - override 'pressure_max' with value from HID_USAGE_PRESSURE

2014-04-19T20:57:34Z

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.
