No fake pressure events please, BTN_TOUCH should be enough.

I'd have to check, IIRC tslib needs these to function properly.

Indeed it does -- otherwise it won't work.  Yes you could try going around and
patching TSLIB but so many people use it that it is principle-of-least-surprise
to produce pressure events.

Drop ABS_PRESSURE.

ok, see above.

The same applies here -- claim ABS_PRESSURE or tslib won't operate with the
touchscreen.

While it is tempting to be 100% exactly correct to what the hardware reports
(which is only TOUCH not PRESSURE) it is preferable to work with the software
which the majority of people use -- namely tslib.

I would strongly argue against removing the ABS_PRESSURE stuff personally,
despite it being essentially a lie.
