2024-08-18Input: i8042 - add forcenorestore quirk to leave controller untouched even on s3Werner Sembach
On s3 resume the i8042 driver tries to restore the controller to a known state by reinitializing things, however this can confuse the controller with different effects. Mostly occasionally unresponsive keyboards after resume. These issues do not rise on s0ix resume as here the controller is assumed to preserved its state from before suspend. This patch adds a quirk for devices where the reinitialization on s3 resume is not needed and might be harmful as described above. It does this by using the s0ix resume code path at selected locations. This new quirk goes beyond what the preexisting reset=never quirk does, which only skips some reinitialization steps.

2024-08-04Input: tsc2004/5 - fix reset handling on probeDmitry Torokhov
When the driver has been converted to use gpiod API it was requesting and asserting the reset on probe, but never deasserted it. However because of incorrect annotations in device tree marking reset line as active high whereas in reality it is active low, the end result was that the chip was never reset on probe. With polarity of the reset line now corrected this became a problem. Fix this by calling tsc200x_reset() from tsc200x_probe() to properly complete the reset sequence and move requesting the reset GPIO and VIO supply closer to the point where we need to start talking to the hardware.

From: Dmitry Torokhov <dmitry.torokhov@gmail.com> When exercising uinput interface syzkaller may try setting up device with a really large number of slots, which causes memory allocation failure in input_mt_init_slots(). While this allocation failure is handled properly and request is rejected, it results in syzkaller reports. Additionally, such request may put undue burden on the system which will try to free a lot of memory for a bogus request. Fix it by limiting allowed number of slots to 100. This can easily be extended if we see devices that can track more than 100 contacts.

It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory.

2024-07-15Input: msc_touchkey - remove the driverDmitry Torokhov
MCS-5000/5080 chips belong to the 1st generation of Melfas chips, manufactured in 2000-2007. The driver relies on custom platform data (no DT support) and there never were any users of this driver in the mainline kernel. It is likely that the driver was (like mcs5000_ts driver) was tested on S3C6410 NCP board (with Samsung S3C6410 SoC), but the touchkey device was never added to the board file. This board was removed in v6.3 in commit 743c8fbb90ca ("ARM: s3c: remove most s3c64xx board support"). Remove the driver since there are no users.
