Input: psmouse - add support for detecting FocalTech PS/2 touchpads The Asus X450 and X550 laptops use a PS/2 touchpad from a new manufacturer called FocalTech: https://bugzilla.kernel.org/show_bug.cgi?id=77391 https://bugzilla.redhat.com/show_bug.cgi?id=1110011 The protocol for these devices is not known at this time, but even without knowing the protocol they need some special handling. They get upset by some of our other PS/2 device probing, and once upset generate random mouse events making things unusable even with an external mouse. This patch adds detection of these devices based on their pnp ids, and when they are detected, treats them as a bare ps/2 mouse. Doing things this way they at least work in their ps/2 mouse emulation mode. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

Input: psmouse - support for the FocalTech PS/2 protocol extensions Most of the protocol for these touchpads has been reverse engineered. This commit adds a basic multitouch-capable driver. A lot of the protocol is still unknown. Especially, we don't know how to identify the device yet apart from the PNP ID. The previous workaround for these devices has been left in place in case the driver is not compiled into the kernel or in case some other device with the same PNP ID is not recognized by the driver yet still has the same problems with the device probing code.

Input: psmouse - rearrange Focaltech init code The fact that we were calling focaltech_init() even when Focaltech support is disabled was confusing. Rearrange the code so that if support is disabled we continue to fall through the rest of protocol probing code until we get to full reset that Focaltech devices need to work properly. Also, replace focaltech_init() with a stub now that it is only called when protocol is enabled.
