2024-02-25iio: accel: adxl367: fix I2C FIFO data registerCosmin Tanislav
As specified in the datasheet, the I2C FIFO data register is 0x18, not 0x42. 0x42 was used by mistake when adapting the ADXL372 driver. Fix this mistake.

2024-02-25iio: accel: adxl367: fix DEVID read after resetCosmin Tanislav
regmap_read_poll_timeout() will not sleep before reading, causing the first read to return -ENXIO on I2C, since the chip does not respond to it while it is being reset. The datasheet specifies that a soft reset operation has a latency of 7.5ms. Add a 15ms sleep between reset and reading the DEVID register, and switch to a simple regmap_read() call.

2023-09-23iio: accel: hid-sensor-accel-3d: Convert to platform remove callback ↵Uwe Kleine-König
returning void The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-05-13iio: accel: kx022a fix irq gettingMatti Vaittinen
The fwnode_irq_get_byname() was returning 0 at device-tree mapping error. If this occurred, the KX022A driver did abort the probe but errorneously directly returned the return value from fwnode_irq_get_byname() from probe. In case of a device-tree mapping error this indicated success. The fwnode_irq_get_byname() has since been fixed to not return zero on error so the check for fwnode_irq_get_byname() can be relaxed to only treat negative values as errors. This will also do decent fix even when backported to branches where fwnode_irq_get_byname() can still return zero on error because KX022A probe should later fail at IRQ requesting and a prober error handling should follow. Relax the return value check for fwnode_irq_get_byname() to only treat negative values as errors.

2023-05-13iio: kx022a: Probe asynchronouslyMatti Vaittinen
Devices which may take a while to initialize during probe and which have no strong reason to probe synchronously can request asynchronous probing as default probe strategy. This can speed-up start times on some platforms. The KX022A gets probe delayed for at least two reasons. It enables the supply regulator, (which is likely to have ramp-up delay if it was disabled) and additionally it delays while the sensor itself is initializing. Changing to asynchronous probing may cause problems. Some of which are discussed in: https://lore.kernel.org/all/06db017f-e985-4434-8d1d-02ca2100cca0@sirena.org.uk/ Enable asynchronous probing for KX022A.
