Input: trackpoint - add new trackpoint firmware ID

2017-11-11T13:34:30+00:00

commit ec667683c532c93fb41e100e5d61a518971060e2 upstream. Synaptics add new TP firmware ID: 0x2 and 0x3, for now both lower 2 bits are indicated as TP. Change the constant to bitwise values. This makes trackpoint to be recognized on Lenovo Carbon X1 Gen5 instead of it being identified as "PS/2 Generic Mouse".

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

2016-08-22T21:37:16+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: synaptics - handle spurious release of trackstick buttons, again

2016-04-30T22:05:19+00:00

commit 82be788c96ed5978d3cb4a00079e26b981a3df3f upstream. Looks like the fimware 8.2 still has the extra buttons spurious release bug. Link: https://bugzilla.kernel.org/show_bug.cgi?id=114321 Signed-off-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov Signed-off-by: Ben Hutchings

Input: elantech - add new icbody type

commit 692dd1916436164e228608803dfb6cb768d6355a upstream. This adds new icbody type to the list recognized by Elantech PS/2 driver. Signed-off-by: Sam Hung Signed-off-by: Dmitry Torokhov Signed-off-by: Ben Hutchings

Input: elantech - support new ICs types for version 4

commit 810aa0918b2b032684c8cad13f73d6ba37ad11c0 upstream. This change allows the driver to recognize newer Elantech touchpads. Signed-off-by: Yi ju Hong Signed-off-by: Dmitry Torokhov Signed-off-by: Ben Hutchings

Input: elantech - add support for newer elantech touchpads

2015-08-06T23:32:15+00:00

commit ae4bedf0679d99f0a9b80a7ea9b8dd205de05d06 upstream. 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. Signed-off-by: Jordan Rife Signed-off-by: Dmitry Torokhov Signed-off-by: Ben Hutchings

Input: elantech - add support for newer (August 2013) devices

2015-08-06T23:32:14+00:00

commit 9cb80b965eaf7af1369f6e16f48a05fbaaccc021 upstream. Added detection for newer Elantech touchpads, so that kernel doesn't fall-back to default PS/2 driver. Supports touchpads released after ~August 2013. Fixes bug: https://lists.launchpad.net/kernel-packages/msg18481.html Tested on an Acer Aspire S7-392-6302.

Input: elantech - fix for newer hardware versions (v7)

2015-08-06T23:32:14+00:00

commit 9eebed7de660c0b5ab129a9de4f89d20b60de68c upstream. * Fix version recognition in elantech_set_properties The new hardware reports itself as v7 but the packets' structure is unaltered. * Fix packet type recognition in elantech_packet_check_v4 The bitmask used for v6 is too wide, only the last three bits of the third byte in a packet (packet[3] & 0x03) are actually used to distinguish between packet types. Starting from v7, additional information (to be interpreted) is stored in the remaining bits (packets[3] & 0x1c). In addition, the value stored in (packet[0] & 0x0c) is no longer a constant but contains additional information yet to be deciphered. This change should be backwards compatible with v6 hardware.

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

2015-08-06T23:32:14+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

2015-08-06T23:32:11+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.
