2024-11-03iio: fix write_event_config signatureJulien Stephan
write_event_config callback use an int for state, but it is actually a boolean. iio_ev_state_store is actually using kstrtobool to check user input, then gives the converted boolean value to write_event_config. Fix signature and update all iio drivers to use the new signature. This patch has been partially written using coccinelle with the following script: $ cat iio-bool.cocci // Options: --all-includes virtual patch @c1@ identifier iioinfo; identifier wecfunc; @@ static const struct iio_info iioinfo = { ..., .write_event_config = ( wecfunc | &wecfunc ), ..., }; @@ identifier c1.wecfunc; identifier indio_dev, chan, type, dir, state; @@ int wecfunc(struct iio_dev *indio_dev, const struct iio_chan_spec *chan, enum iio_event_type type, enum iio_event_direction dir, -int +bool state) { ... } make coccicheck MODE=patch COCCI=iio-bool.cocci M=drivers/iio Unfortunately, this script didn't match all files: * all write_event_config callbacks using iio_device_claim_direct_scoped were not detected and not patched. * all files that do not assign and declare the write_event_config callback in the same file. iio.h was also manually updated. The patch was build tested using allmodconfig config. cc: Julia Lawall <julia.lawall@inria.fr> Signed-off-by: Julien Stephan <jstephan@baylibre.com> Link: https://patch.msgid.link/20241031-iio-fix-write-event-config-signature-v2-7-2bcacbb517a2@baylibre.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

iio_ev_state_store is actually using kstrtobool to check user input, then gives the converted boolean value to the write_event_config callback. Remove useless code in write_event_config callback.

2024-10-02move asm/unaligned.h to linux/unaligned.hAl Viro
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

The driver includes the legacy GPIO header <linux/gpio.h> but doesn't use any symbols from it. Drop it.

2023-10-05iio: irsd200: fix -Warray-bounds bug in irsd200_trigger_handlerGONG, Ruiqi
When compiling with gcc 13 with -Warray-bounds enabled: In file included from drivers/iio/proximity/irsd200.c:15: In function ‘iio_push_to_buffers_with_timestamp’, inlined from ‘irsd200_trigger_handler’ at drivers/iio/proximity/irsd200.c:770:2: ./include/linux/iio/buffer.h:42:46: error: array subscript ‘int64_t {aka long long int}[0]’ is partly outside array bounds of ‘s16[1]’ {aka ‘short int[1]’} [-Werror=array-bounds=] 42 | ((int64_t *)data)[ts_offset] = timestamp; | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~ drivers/iio/proximity/irsd200.c: In function ‘irsd200_trigger_handler’: drivers/iio/proximity/irsd200.c:763:13: note: object ‘buf’ of size 2 763 | s16 buf = 0; | ^~~ The problem seems to be that irsd200_trigger_handler() is taking a s16 variable as an int64_t buffer. As Jonathan suggested [1], fix it by extending the buffer to a two-element array of s64.

2023-07-23iio: Add driver for Murata IRS-D200Waqar Hameed
Murata IRS-D200 is a PIR sensor for human detection. It has support for raw data measurements and detection event notification. Add a driver with support for triggered buffer and events. Map the various settings to the `iio` framework, e.g. threshold values, sampling frequency, filter frequencies etc. Signed-off-by: Waqar Hameed <waqar.hameed@axis.com> Link: https://lore.kernel.org/r/d218a1bc75402b5ebd6e12a563f7315f83fe966c.1689753076.git.waqar.hameed@axis.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
