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

2016-01-12T01:45:32+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: elantech - add special check for fw_version 0x470f01 touchpad

2015-08-07T21:54:15+00:00

It is no need to check the packet[0] for sanity check when doing
elantech_packet_check_v4() function for fw_version = 0x470f01 touchpad.

Input: elantech - force resolution of 31 u/mm

2015-07-16T17:47:31+00:00

All Elantech touchpads pre-v4 with dynamic resolution queries have a fixed
resolution of 800dpi -> 31.49 units/mm. Set this statically, so userspace
does not have to guess.

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

2015-06-02T17:43:07+00:00

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.
