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

2016-02-25T09:49:10+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 - add Fujitsu Lifebook U745 to force crc_enabled

2016-02-25T09:49:10+00:00

commit 60603950f836ef4e88daddf61a273b91e671db2d upstream.

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

Input: psmouse - add small delay for IBM trackpoint pass-through mode

2015-10-28T15:38:29+00:00

commit 66bc2f51ef7deabc8b8f3baa98ae64b65e5e973a upstream.

There are trackpoint devices that fail to respond to the PS2 command
PSMOUSE_CMD_GETID if immediately queried after the parent device is
deactivated. Add a small delay for the hardware to get in a sane state
before sending any PS2 commands.

One example of such a system is:

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

2015-06-23T12:55:11+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

2015-06-03T09:33:14+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.

Input: elantech - fix absolute mode setting on some ASUS laptops

2015-05-04T09:50:01+00:00

commit bd884149aca61de269fd9bad83fe2a4232ffab21 upstream.

On ASUS TP500LN and X750JN, the touchpad absolute mode is reset each
time set_rate is done.

In order to fix this, we will verify the firmware version, and if it
matches the one in those laptops, the set_rate function is overloaded
with a function elantech_set_rate_restore_reg_07 that performs the
set_rate with the original function, followed by a restore of reg_07
(the register that sets the absolute mode on elantech v4 hardware).

Also the ASUS TP500LN and X750JN firmware version, capabilities, and
button constellation is added to elantech.c

Input: elantech - fix crc_enabled for Fujitsu H730

2015-04-27T18:38:19+00:00

commit 0dc1587905a50f8f61bbc29e850aa592821e4bea upstream.

The Fujitsu H730 does not work with crc_enabled = 0, even though the
crc_enabled bit in the firmware version indicated it would. When switching
this value to crc_enabled to 1, the touchpad works. This patch uses DMI to
detect H730.
