2025-07-27Input: Add and document BTN_GRIP*Vicki Pfau
Many controllers these days have started including grip buttons. As there has been no particular assigned BTN_* constants for these, they've been haphazardly assigned to BTN_TRIGGER_HAPPY*. Unfortunately, the assignment of these has varied significantly between drivers. Add and document new constants for these grip buttons.

2025-07-27Input: xpad - change buttons the D-Pad gets mapped as to BTN_DPAD_*Vicki Pfau
Since dance pads can have both up/down or left/right pressed at the same time, by design, they are not suitable for mapping the buttons to axes. Historically, this driver mapped the D-pad to BTN_TRIGGER_HAPPY1-4 in these cases, and before that as mouse buttons. However, BTN_DPAD_* exists for this and makes far more sense than the arbitrary mapping it was before.

2025-07-27gpiolib: enable CONFIG_GPIOLIB_LEGACY even for !GPIOLIBArnd Bergmann
A few drivers that use the legacy GPIOLIB interfaces can be enabled even when GPIOLIB is disabled entirely. With my previous patch this now causes build failures like: drivers/nfc/s3fwrn5/uart.c: In function 's3fwrn82_uart_parse_dt': drivers/nfc/s3fwrn5/uart.c:100:14: error: implicit declaration of function 'gpio_is_valid'; did you mean 'uuid_is_valid'? [-Werror=implicit-function-declaration] These did not show up in my randconfig tests because randconfig almost always has GPIOLIB selected by some other driver, and I did most of the testing with follow-up patches that address the failures properly. Move the symbol outside of the 'if CONFIG_GPIOLIB' block for the moment to avoid the build failures. It can be moved back and turned off by default once all the driver specific changes are merged.

2025-07-26perf parse-events: Remove non-json software eventsIan Rogers
Remove the hard coded encodings from parse-events. This has the consequence that software events are matched using the sysfs/json priority, will be case insensitive and will be wildcarded across PMUs. As there were software and hardware types in the parsing code, the removal means software vs hardware logic can be removed and hardware assumed. Now the perf json provides detailed descriptions of software events, remove the previous listing support that didn't contain event descriptions. When globbing is required for the "sw" option in perf list, use string PMU globbing as was done previously for the tool PMU. The output of `perf list sw` command changed like this. Before: List of pre-defined events (to be used in -e or -M): alignment-faults [Software event] bpf-output [Software event] cgroup-switches [Software event] context-switches OR cs [Software event] cpu-clock [Software event] cpu-migrations OR migrations [Software event] dummy [Software event] emulation-faults [Software event] major-faults [Software event] minor-faults [Software event] page-faults OR faults [Software event] task-clock [Software event] After: List of pre-defined events (to be used in -e or -M): software: alignment-faults [Number of kernel handled memory alignment faults.
