2021-07-06Input: Fix fall-through warning for ClangGustavo A. R. Silva1-0/+1
In preparation to enable -Wimplicit-fallthrough for Clang, fix a warning by explicitly adding a fallthrough; statement. Notice that this seems to be a Duff device for performance[1]. So, although the code looks a bit _funny_, I didn't want to refactor or modify it beyond merely adding a fallthrough marking, which might be the least disruptive way to fix this issue.

2021-07-04Input: joydev - prevent use of not validated data in JSIOCSBTNMAP ioctlAlexander Larkin1-1/+1
Even though we validate user-provided inputs we then traverse past validated data when applying the new map. The issue was originally discovered by Murray McAllister with this simple POC (if the following is executed by an unprivileged user it will instantly panic the system): int main(void) { int fd, ret; unsigned int buffer[10000]; fd = open("/dev/input/js0", O_RDONLY); if (fd == -1) printf("Error opening file\n"); ret = ioctl(fd, JSIOCSBTNMAP & ~IOCSIZE_MASK, &buffer); printf("%d\n", ret); } The solution is to traverse internal buffer which is guaranteed to only contain valid date when constructing the map.

In the case where st->ch_map[GRTS_CH_PRESSURE] < GRTS_MAX_CHANNELS is false and also st->ch_map[GRTS_CH_Z1] < GRTS_MAX_CHANNELS is false the variable press is not initialized and contains garbage. In this situation st->pressure is also false, so we do not actually use press value, but it is impossible for the compiler to realize this, and it emits "uninitialized variable" warning.

At the moment, the edt-ft5x06 driver can control a single regulator ("vcc"). However, some FocalTech touch controllers have an additional IOVCC pin that should be supplied with the digital I/O voltage. The I/O voltage might be provided by another regulator that should also be kept on. Otherwise, the touchscreen can randomly stop functioning if the regulator is turned off because no other components still require it. Implement (optional) support for also enabling an "iovcc-supply". The datasheet specifies a delay of ~ 10us before enabling VDD/VCC after IOVCC is enabled, so make sure to enable IOVCC first.

2021-05-25Input: resistive-adc-touch - add support for z1 and z2 channelsOleksij Rempel1-14/+126
This patch adds support for the z1 and z2 channels. These are used to calculate the applied pressure. As there is no common order of the individual channels of a resistive touch ADC, support for io-channel-names is added (although the DT bindings stated the driver already supports these).

touchscreen_dmi.c Move the DMI quirks for upside-down mounted Goodix touchscreens from drivers/input/touchscreen/goodix.c to drivers/platform/x86/touchscreen_dmi.c, where all the other x86 touchscreen quirks live. Note the touchscreen_dmi.c code attaches standard touchscreen device-properties to an i2c-client device based on a combination of a DMI match + a device-name match. I've verified that the: Teclast X98 Pro, WinBook TW100 and WinBook TW700 uses an ACPI devicename of "GDIX1001:00" based on acpidumps and/or dmesg output available on the web.

There is no reason to pass the ldisc number to tty_register_ldisc separately. Just set it in the already defined tty_ldisc_ops in all the ldiscs.
