Revert "Input: elantech - enable SMBus on new (2018+) systems"

2019-09-06T10:42:01+00:00

This reverts commit 60956b018bfe23b879405a7d88103d0a8f06a5e3 which is commit 883a2a80f79ca5c0c105605fafabd1f3df99b34c upstream. This patch depends on an other series: https://patchwork.kernel.org/project/linux-input/list/?series=122327&state=%2A&archive=both It was a mistake to backport it in the v5.2 branch, as there is a high chance we encounter a touchpad that needs the series above.

Input: elantech - enable SMBus on new (2018+) systems

2019-08-16T08:10:54+00:00

commit 883a2a80f79ca5c0c105605fafabd1f3df99b34c upstream. There are some new HP laptops with Elantech touchpad that don't support multitouch. Currently we use ETP_NEW_IC_SMBUS_HOST_NOTIFY() to check if SMBus is supported, but in addition to firmware version, the bus type also informs us whether the IC can support SMBus. To avoid breaking old ICs, we will only enable SMbus support based the bus type on systems manufactured after 2018. Lastly, let's consolidate all checks into elantech_use_host_notify() and use it to determine whether to use PS/2 or SMBus.

Pull still more SPDX updates from Greg KH: "Another round of SPDX updates for 5.2-rc6 Here is what I am guessing is going to be the last "big" SPDX update for 5.2. It contains all of the remaining GPLv2 and GPLv2+ updates that were "easy" to determine by pattern matching. The ones after this are going to be a bit more difficult and the people on the spdx list will be discussing them on a case-by-case basis now. Another 5000+ files are fixed up, so our overall totals are: Files checked: 64545 Files with SPDX: 45529 Compared to the 5.1 kernel which was: Files checked: 63848 Files with SPDX: 22576 This is a huge improvement. Also, we deleted another 20000 lines of boilerplate license crud, always nice to see in a diffstat" * tag 'spdx-5.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx: (65 commits) treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 507 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 506 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 505 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 504 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 503 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 502 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 501 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 500 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 499 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 498 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 497 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 496 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 495 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 491 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 490 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 489 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 488 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 487 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 486 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 485 ...

Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780

2019-02-08T07:52:06+00:00

Like Fujitsu CELSIUS H760, the H780 also has a three-button Elantech touchpad, but the driver needs to be told so to enable the middle touchpad button. The elantech_dmi_force_crc_enabled quirk was not necessary with the H780. Also document the fw_version and caps values detected for both H760 and H780 models.

Input: elantech - disable elan-i2c for P52 and P72

2018-12-21T08:57:01+00:00

The current implementation of elan_i2c is known to not support those 2 laptops. A proper fix is to tweak both elantech and elan_i2c to transmit the correct information from PS/2, which would make a bad candidate for stable. So to give us some time for fixing the root of the problem, disable elan_i2c for the devices we know are not behaving properly.
