Subject[PATCH v3 0/4] Cypress PS/2 Trackpad driver
Date
This driver, submitted on behalf of Cypress Semiconductor Corporation and
additional contributors, provides support for the Cypress PS/2 Trackpad.

This [PATCH v3] version differs from my previous submitted version[1]:

Patch #1 (cmdbuf to 8 bytes) and #3 (link in driver) are unchanged.

Patch #2 (main driver), as recommended by Henrik Rydberg[2]:
- use input_mt_assign_slots; drop cypress_cal_finger_id.
- enable 2-finger-only SEMI_MT; drop cypress_simulate_fingers.
- various code clean-ups.

Henrik, does patch #2 appear to properly use assign_slots and SEMI_MT as
you intended? This SEMI_MT method does work (with 2 finger support only),
but I'm not clear why we wouldn't want to handle >2 fingers also, so ...

Patch #4 (new) reintroduces simulated multitouch for up to 5 fingers
(#if CYPRESS_SIMULATE_MT), disabling SEMI_MT again.

If that functionality (support for >2 fingers) can be acheived in some
better way, please advise.


Remaining known problems (assistance or advice appreciated):

- Multitouch >2 fingers does not work after rmmod/insmod, and stops
working after suspend/resume. Restarting X fixes it in both cases.

- cypress_reconnect() never actually works, so I disabled it; just let
psmouse re-init the driver instead, which works and is what was ending
up happenning anyway.
