Move active low and open drain register definitions in hw_settings register map since not all supported sensors (e.g lsm9ds1) rely on the same definitions Fixes: 52f4b1f1 ("iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1") Signed-off-by:

Miquel Raynal authored
The chips have a 'start conversion' and a 'end of conversion' pair of pins. They can be used but this is absolutely not mandatory as regular polling is supported by the chip depending on its internal clocking setup. There is no physical reason to force the use of interrupts so turn them optional. Also, once the interrupt turned optional, these devices fit perfectly the "trivial devices" described in the generic (yaml) bindings file, so instead of converting this text file to json schema, we can just add the relevant compatibles in: Documentation/devicetree/bindings/trivial-devices.yaml.

Maxim's max12xx series is very similar to the max10xx series, with the difference of the measurements depth which is upgraded from 10 to 12 bits per channel. Everything else looks the same. Signed-off-by:

Miquel Raynal authored
Maxim's max1027/29/31 series returns the measured voltages with a resolution of 10 bits. There is a very similar series, max1227/29/31 which works identically but uses a resolution of 12 bits. Prepare the support for these chips by turning the 'depth' into a macro parameter instead of hardcoding it everywhere. Also reorganize just a bit the macros at the top to avoid repeating tens of lines when adding support for a new chip. Signed-off-by:

Miquel Raynal authored
The chip has a 'start conversion' and a 'end of conversion' pair of pins. They can be used but this is absolutely not mandatory as regular polling of the value is totally fine with the current internal clocking setup. Turn the interrupts optional and do not error out if they are not inquired in the device tree. This has the effect to prevent triggered buffers use though. Signed-off-by:

Miquel Raynal authored
Until now, only write operations were supported. Force two bytes read operation when reading, which should fit most of the development purposes. Of course, extended operations like buffered reads on multiple channels or even temperature + voltage reads will not be read entirely. Usually, just starting a new operation will work but in any case a software reset (done through the debufs interface too) will return the device in a usable state. Signed-off-by:

Since wfx_tx_get_raw_link_id() return an unsigned, it makes no sense to return a negative value. "15" is a better value since it is used by firmware for stations that have not yet associated link-ids. Note that this should never happens since driver set max_ap_assoc_sta to 14.

Merge tag 'iio-for-5.5a-take3' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First set of IIO new device support, cleanups and features for the 5.5 cycle Third version with the adis rework set dropped as better to just have a fresh version of that at some future date. The usual mixed backs of new device support being added to drivers, long term reworks continuing and little per driver cleanups and features. Also a few trivial counter subsystem tidy ups on behalf of William. Core new feature * Device label support. A long requested feature no one got around to implementing before. Allows DT based provision of a 'label' that identifies a device uniquely within a system. This differs from existing 'name' which is meant to be the part number. New device support * ingenic-adc - Support for the JZ4770 SoC ADC including bindings. * inv_mpu6050 - Add support for magnetometer in MPU925x parts. Fiddly to do as this is actually a separate device sitting inside the package, but with the master device being able to schedule reads etc. Will only run if the auxiliary bus is not in use for any other devices. Features * ad7192 - Userspace calibration controls to do zero and full scale. * st_lsm6dsx - Enable latched interrupts by default for sensors events with related clear. - Motion events and related wakeup source. This needed quite a bit of refactoring as well. Cleanups and minor features * ad7192 - sysfs ABI docs * ad7949 - Remove code to readback configuration word as driver never actually enabled it. - Fix incorrect xfer length. Not actually known to cause problems other than wasted bus usage. * adis16080 - Replace core mlock usage with local lock with more appropriate scope. * adis16130 - Remove pointless mlock usage. * adis16240 - Remove include of gpio.h as no gpio usage. * atlas-ph-sensor - Improve logical ordering of buffer predisable / postenable functions. This is part of a longer term rework Alexandru is driving towards. * bh1750 - Fix up a static compiler warning and make the code more readable. - yaml conversion of binding + MAINTAINERS entry. * bmp280 - Drop a stray newline. * cm36651 - Drop a redundant assignment * itg3200 - Alignment cleanup. * max31856 - Add missing of_node and parent references, useful to identify the device. * sc27xx_adc - Use devm_hwspin_lock_request_specific rather than local rolled version. * stm32-lptimer counter - kernel-doc warning. * stm32-timer counter - kernel-doc warning. - Alignment cleanup. * sx9500 - Improve logical ordering of buffer predisable / postenable functions. This is part of a longer term rework Alexandru is driving towards. * tcs3414 - Improve logical ordering of buffer predisable / postenable functions. This is part of a longer term rework Alexandru is driving towards. * tag 'iio-for-5.5a-take3' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (41 commits) iio: pressure: bmp280: remove stray newline iio: adc: sc27xx: Use devm_hwspin_lock_request_specific() to simplify code iio: chemical: atlas-ph-sensor: fix iio_triggered_buffer_predisable() position iio: gyro: clean up indentation issue counter: stm32: clean up indentation issue iio: proximity: sx9500: fix iio_triggered_buffer_{predisable,postenable} positions iio: core: Add optional symbolic label to device attributes dt-binding: iio: Add optional label property iio: gyro: adis16080: replace mlock with own lock counter: stm32-lptimer-cnt: fix a kernel-doc warning counter: stm32-timer-cnt: fix a kernel-doc warning iio: gyro: adis16130: remove mlock usage MAINTAINERS: add entry for ROHM BH1750 driver dt-bindings: iio: light: bh1750: convert bindings to yaml iio: imu: st_lsm6dsx: add motion report function and call from interrupt iio: imu: st_lsm6dsx: always enter interrupt thread iio: imu: st_lsm6dsx: add wakeup-source option iio: imu: st_lsm6dsx: add motion events iio: imu: st_lsm6dsx: move interrupt thread to core iio: imu: inv_mpu6050: add fifo support for magnetometer data ...

The iio_triggered_buffer_{predisable,postenable} functions attach/detach the poll functions. The iio_triggered_buffer_predisable() should be called last, to detach the poll func after the devices has been suspended. The position of iio_triggered_buffer_postenable() is correct. Note this is not stable material. It's a fix in the logical model rather fixing an actual bug. These are being tidied up throughout the subsystem to allow more substantial rework that was blocked by variations in how things were done.
