Subject: [PATCH v2 0/3] Cypress PS/2 Trackpad driver

This driver, submitted on behalf of Cypress Semiconductor Corporation and
additional contributors, provides support for the Cypress PS/2 Trackpad.

This [PATCH v2] version differs from my first submission[0]:

 - Increases the size the of the cmdbuf[] array in struct ps2dev from
   6 to 8 bytes, per Dmitry Torokhov's suggestion.  ** This change has
   not been tested with respect to any other touchpads.  Is it safe? **

 - Removes the special Cypress handling from psmouse-base.c

And it *almost* works properly... Cypress PS/2 Trackpad is recognized and
works fine on boot, but after a suspend-resume multitouch features no longer
work (one and two finger tap works, but three does not).  Restarting X does
fix it, until the next suspend.  The previous version of the driver[0] does
not exhibit that problem.

Help identifying and fixing the suspend-resume issue will be much
appreciated.
