2021-10-15Input: resistive-adc-touch - fix division by zero error on z1 == 0Oleksij Rempel
For proper pressure calculation we need at least x and z1 to be non zero. Even worse, in case z1 we may run in to division by zero error.

2021-10-15Input: snvs_pwrkey - add clk handlingUwe Kleine-König
On i.MX7S and i.MX8M* (but not i.MX6*) the pwrkey device has an associated clock. Accessing the registers requires that this clock is enabled. Binding the driver on at least i.MX7S and i.MX8MP while not having the clock enabled results in a complete hang of the machine. (This usually only happens if snvs_pwrkey is built as a module and the rtc-snvs driver isn't already bound because at bootup the required clk is on and only gets disabled when the clk framework disables unused clks late during boot.) This completes the fix in commit 135be16d3505 ("ARM: dts: imx7s: add snvs clock to pwrkey").

2021-10-15Input: tm2-touchkey - allow changing keycodes from userspaceStephan Gerhold
At the moment the touch keys have key codes assigned from the device tree. In some cases, users might want to change the key code from userspace. There is existing functionality for this in the input core using the EVIOCSKEYCODE ioctl, which is integrated for example into udev.

2021-10-11Input: st1232 - increase "wait ready" timeoutJohn Keeping
I have a ST1633 touch controller which fails to probe due to a timeout waiting for the controller to become ready. Increasing the minimum delay to 100ms ensures that the probe sequence completes successfully. The ST1633 datasheet says nothing about the maximum delay here and the ST1232 I2C protocol document says "wait until" with no notion of a timeout. Since this only runs once during probe, being generous with the timout seems reasonable and most likely the device will become ready eventually. (It may be worth noting that I saw this issue with a PREEMPT_RT patched kernel which probably has tighter wakeups from usleep_range() than other preemption models.)

2021-09-20Input: goodix - add support for controllers without flashHans de Goede
Some Goodix touchscreen controllers, such as for example the GT912, don't have flash-storage for their firmware. These models require the OS to load the firmware at runtime, as well as some other special handling. Add support for this to the goodix driver. This patch was developed and tested on a Glavey TM800A550L tablet. Note the "goodix,main-clk" and "firmware-name" device-properties used by the new code are *not* documented in the Documentation/devicetree/bindings/input/touchscreen/goodix.yaml device-tree bindings for now. Not documenting these is intentional. This is done because this code has only been tested on x86/ACPI so far, where devicetree is not used. Instead these properties are set through a software-fwnode attached to the device by the drivers/platform/x86/touchscreen_dmi.c code. This means that the use of this properties for now is purely a kernel-internal thing and the name/working of the properties may still be changed for now.

As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. So, use the struct_size() helper to do the arithmetic instead of the argument "size + count * size" in the kzalloc() function.
