2010-08-28Input: wacom_w8001 - add multitouch slot supportPeter Hutterer
Some serial wacom devices support two-finger touch. Test for this during init and parse the touch packets accordingly. Touch packets are processed using Protocol B (MT Slots). Note: there are several wacom versions that do touch but not two-finger touch. These are not catered for here, touch events for these are simply discarded.

2010-08-28Input: wacom_w8001 - support (and ignore) touch tabletsPeter Hutterer
Tablets that support touch input may report different sized packages, depending on the touch sensor in the tablet. For now, discard the packages until we report them as touch input proper. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2010-08-28Input: wacom_w8001 - send BTN_TOOL_PEN/RUBBER and BTN_STYLUS eventsPeter Hutterer
The protocol used by the w8001 supports status fields for tip, side switch and eraser as well as a RDY field for proximity. The protocol has a double usage for the f2 bit in the packet. If set, the data is either pen + side2 button or eraser. Assume eraser if the device comes into proximity with the f2 bit set, otherwise trigger the side2 button. If the device comes into proximity with the f2 bit and that bit disappears afterwards, fake proximity out for the eraser and proximity in for the pen.

There is no need for locking when we send query and start commands to the touchscreen since there is no concurrency. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
