Input: elantech - fix touchpad initialization on Gigabyte U2442

2014-05-05T19:34:22+00:00

The hw_version 3 Elantech touchpad on the Gigabyte U2442 does not accept
0x0b as initialization value for r10, this stand-alone version of the
driver: http://planet76.com/drivers/elantech/psmouse-elantech-v6.tar.bz2

Uses 0x03 which does work, so this means not setting bit 3 of r10 which
sets: "Enable Real H/W Resolution In Absolute mode"

Which will result in half the x and y resolution we get with that bit set,
so simply not setting it everywhere is not a solution. We've been unable to
find a way to identify touchpads where setting the bit will fail, so this
patch uses a dmi based blacklist for this.

Input: elantech - add support for newer elantech touchpads

2014-04-23T05:56:41+00:00

Newer elantech touchpads are not recognized by the current driver, since it
fails to detect their firmware version number. This prevents more advanced
touchpad features from being usable such as two-finger scrolling. This
patch allows newer touchpads to be detected and be fully functional. Tested
on Sony Vaio SVF13N17PXB.

Input: synaptics - add min/max quirk for ThinkPad T431s, L440, L540, S1 Yoga and X1

2014-04-20T05:44:21+00:00

We expect that all the Haswell series will need such quirks, sigh.

The T431s seems to be T430 hardware in a T440s case, using the T440s touchpad,
with the same min/max issue.

The X1 Carbon 3rd generation name says 2nd while it is a 3rd generation.

The X1 and T431s share a PnPID with the T540p, but the reported ranges are
closer to those of the T440s.

HdG: Squashed 5 quirk patches into one. T431s + L440 + L540 are written by me,
S1 Yoga and X1 are written by Benjamin Tissoires.

Hdg: Standardized S1 Yoga and X1 values, Yoga uses the same touchpad as the
X240, X1 uses the same touchpad as the T440.

First round of input updates for 3.15.

Input: appletouch - fix jumps when additional fingers are detected

2014-03-31T06:44:17+00:00

Addresses issues related to when a second finger enters or leaves the
field, causing the cursor to jump or the page to scroll unexpectedly; now,
we discard any movement change that happens at the exact moment we detect a
change in the number of fingers touching the trackpad. This doesn't
completely resolve the issue but does greatly mitigate it.

Input: appletouch - implement sensor data smoothing

2014-03-31T06:44:14+00:00

Use smoothed version of sensor array data to calculate movement and add
weight to prior values when calculating average. This gives more granular
and more predictable movement.

Input: synaptics - add manual min/max quirk

2014-03-28T16:02:00+00:00

The new Lenovo Haswell series (-40's) contains a new Synaptics touchpad.
However, these new Synaptics devices report bad axis ranges.
Under Windows, it is not a problem because the Windows driver uses RMI4
over SMBus to talk to the device. Under Linux, we are using the PS/2
fallback interface and it occurs the reported ranges are wrong.

Of course, it would be too easy to have only one range for the whole
series, each touchpad seems to be calibrated in a different way.

We can not use SMBus to get the actual range because I suspect the firmware
will switch into the SMBus mode and stop talking through PS/2 (this is the
case for hybrid HID over I2C / PS/2 Synaptics touchpads).

So as a temporary solution (until RMI4 land into upstream), start a new
list of quirks with the min/max manually set.
