Subject: [PATCH v2 0/3] Cypress PS/2 Trackpad driver
Date: Tue, 20 Nov 2012 13:30:07 -0800 [thread overview]
Message-ID: <1353447010-4852-1-git-send-email-kamal@canonical.com> (raw)
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.
