Input: synaptics - handle spurious release of trackstick buttons, again

2016-04-12T14:33:48+00:00

commit 82be788c96ed5978d3cb4a00079e26b981a3df3f upstream.

Looks like the fimware 8.2 still has the extra buttons spurious release
bug.

Input: vmmouse - fix absolute device registration

2016-01-28T00:03:30+00:00

We should set device's capabilities first, and then register it,
otherwise various handlers already present in the kernel will not be
able to connect to the device.

Input: elantech - mark protocols v2 and v3 as semi-mt

2016-01-12T01:45:32+00:00

When using a protocol v2 or v3 hardware, elantech uses the function
elantech_report_semi_mt_data() to report data. This devices are rather
creepy because if num_finger is 3, (x2,y2) is (0,0). Yes, only one valid
touch is reported.

Anyway, userspace (libinput) is now confused by these (0,0) touches,
and detect them as palm, and rejects them.

Commit 3c0213d17a09 ("Input: elantech - fix semi-mt protocol for v3 HW")
was sufficient enough for xf86-input-synaptics and libinput before it has
palm rejection. Now we need to actually tell libinput that this device is
a semi-mt one and it should not rely on the actual values of the 2 touches.

Input: ALPS - report v3 pinnacle trackstick device only if is present

2016-01-07T00:06:47+00:00

This patch moves v3 pinnacle code for trackstick detection from
alps_hw_init_v3() to alps_set_protocol() so ALPS_DUALPOINT flag can be
cleared before registering trackstick input device in kernel.

Input: ALPS - detect trackstick presence for v7 protocol

2016-01-07T00:06:46+00:00

This patch adds detection of trackstick for v7 protocol devices. Code in
this patch is used in official Dell touchpad linux drivers for Dell models:
Dell Latitude E5250/5250, E5450/5450, E5550/5550

Detection code and base reg for alps v3 rushmore and v7 devices is exacly
same.

Also user in bug https://bugzilla.kernel.org/show_bug.cgi?id=94801 reported
that Toshiba Sattellite Z30-A-1DG has only alps v7 touchpad device without
trackstick and kernel reports to userspace also redundant trackstick
device.

Merge branch 'psmouse-passthrough' into next

2015-12-17T23:25:10+00:00

Bring in changes to limit number of protocols we try on pass-though PS/2
ports so that probe ocmpletes faster.

Input: psmouse - rename ps2pp_init() to ps2pp_detect()

2015-12-17T23:24:37+00:00

This makes Logitech PS2++ protocol implementation consistent with
the naming in other protocols. Also mark the stub as "static inline"

Input: psmouse - limit protocols that we try on passthrough ports

2015-12-17T23:24:32+00:00

PS/2 protocol is slow, and using it with pass-through port (where we
encapsulate PS/2 into PS/2) is slower yet so it takes quite a bit of time
to do full protocol discovery for device attached to a pass-through port.
However, so far we have not see anything but trackpoints or basic PS/2
mice on pass-through ports, so let's limit protocols that we probe there
to Trackpoint, IntelliMouse Explorer, IntelliMouse, and bare PS/2 protocol,
and avoid other extended protocols, such as Synaptics, ALPS, etc.

Input: psmouse - factor out common protocol probing code

2015-12-17T23:24:21+00:00

In preparation of limiting protocols that we try on pass-through ports,
let's rework initialization code and factor common code into
psmouse_try_protocol() that accepts protocol type (instead of detec()
function pointer) and can, for most protocols, perform both detection and
initialization.

Note that this removes option of forcing Lifebook protocol on devices that
are not recognized by lifebook_detect() as having the hardware, but I do
not recall anyone using this option.
