kernel/drivers/input/mouse/cyapa_gen3.c, branch linux-6.18.y

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

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: mouse - use sysfs_emit[_at]() instead of scnprintf()

2023-12-14T05:26:11Z

Replace the calls to various *printf() functions with sysfs_emit() to simplify the code. Signed-off-by: ye xingchen Link: https://lore.kernel.org/r/202212021453578171100@zte.com.cn Signed-off-by: Dmitry Torokhov

Input: use input_device_enabled()

2020-12-03T06:10:33Z

Use the newly added helper in relevant input drivers. Signed-off-by: Andrzej Pietrasiewicz Link: https://lore.kernel.org/r/20200608112211.12125-3-andrzej.p@collabora.com Signed-off-by: Dmitry Torokhov

Input: Use fallthrough pseudo-keyword

2020-07-07T18:25:54Z

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-throughs

2018-10-15T18:24:10Z

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 - remove duplicated macro definitions

2018-01-09T01:42:00Z

Apart from whitespace differences, this block of macros is repeated twice: $ x=./drivers/input/mouse/cyapa_gen3.c; diff -w -u <(sed -n '139,181p' $x) <(sed -n '182,224p' $x) $ Signed-off-by: Rasmus Villemoes Signed-off-by: Dmitry Torokhov

Input: cyapa - use msleep() for long delay

2017-01-15T23:40:23Z

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. Signed-off-by: Nicholas Mc Guire Signed-off-by: Dmitry Torokhov

Input: cyapa - use time based retry loop

2017-01-15T23:40:11Z

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(). Signed-off-by: Nicholas Mc Guire Signed-off-by: Dmitry Torokhov

Input: cyapa - fix for losing events during device power transitions

2016-03-04T19:32:13Z

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. Signed-off-by: Dudley Du Tested-by: Jeremiah Mahler Signed-off-by: Dmitry Torokhov

Input: cyapa - fully support runtime suspend power management

Fix the the runtime suspend power management not working issue when system starts up and before user touches the trackpad device. TEST=test on Chromebook. Signed-off-by: Dudley Du Signed-off-by: Dmitry Torokhov
