2022-09-05iio: pressure: icp10100: Switch from UNIVERSAL to DEFINE_RUNTIME_DEV_PM_OPS().Jonathan Cameron
The suspend and resume callbacks in this driver appear to be safe to call repeatedly, but why do so when we can use the DEFINE_RUNTIME_DEV_PM_OPS() macro to supply callbacks that check if we are already runtime suspended before doing unnecessary work.

data Back in the days of board files, platform data was used to provide information on the mapping from ADC channel to an analog signal from another device. We've long since moved to doing this via device tree. Hence drop the support from the max1363 driver which is the only driver still providing this.

2022-09-05iio: accel: bma400: Add support for single and double tap eventsJagath Jog J

2022-09-05iio: Add new event type gesture and use direction for single and double tapJagath Jog J
Add new event type for tap called gesture and the direction can be used to differentiate single and double tap. This may be used by accelerometer sensors to express single and double tap events. For directional tap, modifiers like IIO_MOD_(X/Y/Z) can be used along with singletap and doubletap direction.

2022-09-05iio: Use per-device lockdep class for mlockVincent Whitchurch
If an IIO driver uses callbacks from another IIO driver and calls iio_channel_start_all_cb() from one of its buffer setup ops, then lockdep complains due to the lock nesting, as in the below example with lmp91000. Since the locks are being taken on different IIO devices, there is no actual deadlock. Fix the warning by telling lockdep to use a different class for each iio_device. ============================================ WARNING: possible recursive locking detected -------------------------------------------- python3/23 is trying to acquire lock: (&indio_dev->mlock){+.+.}-{3:3}, at: iio_update_buffers but task is already holding lock: (&indio_dev->mlock){+.+.}-{3:3}, at: enable_store other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&indio_dev->mlock); lock(&indio_dev->mlock); *** DEADLOCK *** May be due to missing lock nesting notation 5 locks held by python3/23: #0: (sb_writers#5){.+.+}-{0:0}, at: ksys_write #1: (&of->mutex){+.+.}-{3:3}, at: kernfs_fop_write_iter #2: (kn->active#14){.+.+}-{0:0}, at: kernfs_fop_write_iter #3: (&indio_dev->mlock){+.+.}-{3:3}, at: enable_store #4: (&iio_dev_opaque->info_exist_lock){+.+.}-{3:3}, at: iio_update_buffers Call Trace: __mutex_lock iio_update_buffers iio_channel_start_all_cb lmp91000_buffer_postenable __iio_update_buffers enable_store Fixes: 67e17300dc1d76 ("iio: potentiostat: add LMP91000 support") Signed-off-by: Vincent Whitchurch <vincent.whitchurch@axis.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Link: https://lore.kernel.org/r/20220829091840.2791846-1-vincent.whitchurch@axis.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

2022-08-30iio: light: ltrf216a: Add raw attributeShreeya Patel
Add IIO_CHAN_INFO_RAW to the mask to be able to read raw values from the light sensor. The userspace code for brightness control in steam deck uses the in_illuminance_input value through sysfs and multiplies it with a constant stored in BIOS at factory calibration time. The downstream driver for LTRF216A that we have been using has incorrect formula for LUX calculation which we corrected in the upstreamed driver. Now to be able to use the upstreamed driver, we need to add some magic in userspace so that the brightness control works like before even with the updated LUX formula. Hence, we need the raw data to calculate a constant that can be added in userspace code. Downstream driver LUX formula :- (greendata*8*LTRF216A_WIN_FAC) / (data->als_gain_fac*data->int_time_fac*10) Upstreamed driver LUX formula :- (greendata*45*LTRF216A_WIN_FAC) / (data->als_gain_fac*data->int_time_fac) greendata is the ALS_DATA which we would like to get through sysfs using the raw attribute.

2022-08-15iio: magnetometer: yas530: Add YAS537 variantJakob Hauser
Add support for the magnetometer Yamaha YAS537. The additions are based on comparison of Yamaha Android kernel drivers for YAS532 [1] and YAS537 [2]. In the Yamaha YAS537 Android driver, there is an overflow/underflow control implemented. For regular usage, this seems not necessary. A similar overflow/ underflow control of Yamaha YAS530/532 Android driver isn't integrated in the mainline driver. It is therefore skipped for YAS537 in the mainline too. Also in the Yamaha YAS537 Android driver, at the end of the reset_yas537() function, a measurement is saved in "last_after_rcoil". Later on, this is compared to current measurements. If the difference gets too big, a new reset is initialized. The difference in measurements needs to be quite big, it's hard to say if this is necessary for regular operation. Therefore this isn't integrated in the mainline driver either.

2022-08-15iio: magnetometer: yas530: Add function pointers to "chip_info"Jakob Hauser
Add function pointers to the "chip_info" structure to ease the handling of different YAS variants. In the function yas5xx_probe(), the function call for "measure_offsets" was added as a conditional "if (ci->measure_offsets)". This is a preparatory step for YAS537, as this variant doesn't need an offset measurement.
