Input: elantech - fix protocol errors for some trackpoints in SMBus mode

2020-12-11T08:15:05Z

There are some version of Elan trackpads that send incorrect data when in SMbus mode, unless they are switched to use 0x5f reports instead of standard 0x5e. This patch implements querying device to retrieve chips identifying data, and switching it, when needed to the alternative report.

Input: Use fallthrough pseudo-keyword

2020-07-07T18:25:54Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

Input: elantech - remove redundant assignments to variable error

2020-07-07T00:53:33Z

The variable error is being initialized with a value that is never read and it is being updated later with a new value. The initialization is redundant and can be removed.

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

2019-10-16T00:42:47Z

This reverts commit 883a2a80f79ca5c0c105605fafabd1f3df99b34c. Apparently use dmi_get_bios_year() as manufacturing date isn't accurate and this breaks older laptops with new BIOS update. So let's revert this patch. There are still new HP laptops still need to use SMBus to support all features, but it'll be enabled via a whitelist.

Input: elantech - annotate fall-through case in elantech_use_host_notify()

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

2019-07-23T13:49:22Z

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.

Merge tag 'v5.2' into next

2019-07-15T16:42:32Z

Sync up with mainline to resolve conflicts in iforce driver.

Merge tag 'spdx-5.2-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/spdx

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 ...
