Input: alps - fix v4 button press recognition

2014-10-15T17:57:19+00:00

Since the change to struct input_mt_pos some variables are now bitfields
instead of integers. Automatic conversion from integer to bitfield entry
destroys information, therefore enforce boolean interpretation instead.

Input: synaptics - gate forcepad support by DMI check

2014-10-11T18:34:42+00:00

Unfortunately, ForcePad capability is not actually exported over PS/2, so
we have to resort to DMI checks.

Synchronize with mainline to bring in changes to Synaptics and i8042
drivers.

Input: psmouse - add support for detecting FocalTech PS/2 touchpads

2014-09-15T21:30:46+00:00

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.

Input: psmouse - add psmouse_matches_pnp_id helper function

2014-09-13T00:30:44+00:00

The matches_pnp_id function from the synaptics driver is useful for other
drivers too. Make it a generic psmouse helper function.

Input: synaptics - add support for ForcePads

2014-09-09T23:52:28+00:00

ForcePads are found on HP EliteBook 1040 laptops. They lack any kind of
physical buttons, instead they generate primary button click when user
presses somewhat hard on the surface of the touchpad. Unfortunately they
also report primary button click whenever there are 2 or more contacts
on the pad, messing up all multi-finger gestures (2-finger scrolling,
multi-finger tapping, etc). To cope with this behavior we introduce a
delay (currently 50 msecs) in reporting primary press in case more
contacts appear.

Input: add missing POINTER / DIRECT properties to a bunch of drivers

2014-09-08T21:58:12+00:00

I've not done a full audit of all mouse drivers, I noticed these ones were
missing the POINTER property while working on the POINTING_STICK property.

Input: add INPUT_PROP_POINTING_STICK property

2014-09-08T21:58:11+00:00

It is useful for userspace to know that there not dealing with a regular
mouse but rather with a pointing stick (e.g. a trackpoint) so that
userspace can e.g. automatically enable middle button scrollwheel
emulation.

It is impossible to tell the difference from the evdev info without
resorting to putting a list of device / driver names in userspace, this is
undesirable.

Add a property which allows userspace to see if a device is a pointing
stick, and set it on all the pointing stick drivers.

Input: elantech - add support for trackpoint found on some v3 models

2014-08-26T22:17:41+00:00

Some elantech v3 touchpad equipped laptops also have a trackpoint, before
this commit, these give sync errors. With this patch, the trackpoint is
provided as another input device: 'Elantech PS/2 TrackPoint'

The patch will also output messages that do not follow the expected pattern.
In the mean time I've seen 2 unknown packets occasionally:
0x04 , 0x00 , 0x00 , 0x00 , 0x00 , 0x00
0x00 , 0x00 , 0x00 , 0x02 , 0x00 , 0x00
I don't know what those are for, but they can be safely ignored.

Currently all packets that are not known to v3 touchpad and where
packet[3] (the fourth byte) lowest nibble is 6 are now recognized as
PACKET_TRACKPOINT and processed by the new elantech_report_trackpoint.

This has been verified to work on a laptop Lenovo L530 where the
touchpad/trackpoint combined identify themselves as:
psmouse serio1: elantech: assuming hardware version 3 (with firmware version 0x350f02)
psmouse serio1: elantech: Synaptics capabilities query result 0xb9, 0x15, 0x0c.
