Input: elantech - add Fujitsu Lifebook E556 to force crc_enabled

2017-02-23T03:54:10+00:00

commit 62837b3c1a95535d1a287c9c8c6563bbd8d37033 upstream.

Another Lifebook machine that needs the same quirk as other similar
models to make the driver working.

Also let's reorder elantech_dmi_force_crc_enabled list so LIfebook enries
are in alphabetical order.

Input: elantech - add more IC body types to the list

2016-08-22T21:38:19+00:00

commit 226ba707744a51acb4244724e09caacb1d96aed9 upstream.

The touchpad in HP Pavilion 14-ab057ca reports it's version as 12 and
according to Elan both 11 and 12 are valid IC types and should be
identified as hw_version 4.

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

2016-02-02T19:09:29+00:00

commit 6544a1df11c48c8413071aac3316792e4678fbfb upstream.

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: elantech - fix detection of touchpads where the revision matches a known rate

2015-06-11T10:24:59+00:00

commit 5f0ee9d17aae628b22be86966471db65be21f262 upstream.

Make the check to skip the rate check more lax, so that it applies
to all hw_version 4 models.

This fixes the touchpad not being detected properly on Asus PU551LA
laptops.

Input: elantech - fix semi-mt protocol for v3 HW

2015-06-02T11:08:15+00:00

commit 3c0213d17a09601e0c6c0ae0e27caf70d988290f upstream.

When the v3 hardware sees more than one finger, it uses the semi-mt
protocol to report the touches. However, it currently works when
num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1
finger as if num_fingers was 1.

This confuses userspace which knows how to deal with extra fingers
when all the slots are used, but not when some are missing.
