* move asm/unaligned.h to linux/unaligned.hAl Viro2024-10-021-1/+1
| | | | | | | | | | | | | | | | | | | asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

* Input: Use fallthrough pseudo-keywordGustavo A. R. Silva2020-07-071-2/+2
| | | | | | | | | | | | 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: cyapa - mark expected switch fall-throughsGustavo A. R. Silva2018-10-151-2/+2
| | | | | | | | | | | | | In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. Notice that in this particular case, I replaced the "Fallthrough state" commern with a proper "Fall through", which is what GCC is expecting to find.

* Input: cyapa - use msleep() for long delayNicholas Mc Guire2017-01-161-1/+1
| | | | | | | | | ulseep_range() uses hrtimers and provides no advantage over msleep() for larger delays. Fix up the 50ms delays here to use msleep() and reduce the load on the hrtimer subsystem.

* Input: cyapa - use time based retry loopNicholas Mc Guire2017-01-161-15/+12
| | | | | | | | | | | | | Using counter based retry loops for peripherals results in the delay being significantly overrun during high-load situations where delay functions tend to be vary imprecise and overrun there timeouts. So condition the termination on the actual condition of 2s for the re-calibration to have been successful. As this is a very long delay there is no advantage in using high-resolution timers thus switching this to msleep().

* Input: cyapa - fix for losing events during device power transitionsDudley Du2016-03-041-29/+79
| | | | | | | | | | | | | | | | | When changing the scan rate as part of runtime-resume process we may lose some of the events, because: 1) for gen3 trackpads, the driver must msleep() some time to ensure that the device is ready to accept next command; 2) for gen5 and later trackpads, the queue dumping function will simply ignore the events when waiting for the set power mode command response. The solution is to keep polling and report those valid events when the set power mode command is in progress.

* Input: cyapa - re-design driver to support multi-trackpad in one driverDudley Du2015-01-181-0/+807
In order to support multiple different chipsets and communication protocols trackpad devices in one cyapa driver, the new cyapa driver is re-designed with one cyapa driver core and multiple device specific functions component. The cyapa driver core is contained in this patch, it supplies basic functions that working with kernel and input subsystem, and also supplies the interfaces that the specific devices' component can connect and work together with as one driver.
