There is nothing else that needs to be done for this driver. The remove hook calls only the iio_device_unregister() hook. So this driver can use devm_iio_device_register() directly. Signed-off-by:

This change converts the probe of the AD5064 driver to use only device-managed functions. The regulator_bulk_disable() is passed on a devm_add_action_or_reset() hook and the devm_iio_device_register() can be used to register the IIO device. The driver has both I2C and SPI hooks inside, so all these can be removed. Signed-off-by:

This change does a conversion of the driver to use device-managed init functions. The 2 regulators and the clock inits are converted to use devm_add_action_or_reset() callbacks for de-initializing them when the driver unloads. And finally the devm_iio_device_register() function can be use to register the device. The remove hook can finally be removed and the spi_set_drvdata() call can also be removed as the private data is no longer used. Signed-off-by:

For this conversion, the regulators need to have some cleanup hooks registered with devm_add_action_or_reset() and then the devm_io_device_register() call can be used. Signed-off-by:

Some platforms have separated the end-of-conversion information from the usual ISR/IMR/IER/IDR registers, into EOC_ISR/EOC_IMR/EOC_IER/EOC_IDR. To cope with both variants, helpers are being added, that will make code more clear and more easy to read. Signed-off-by:

Convert the driver to platform specific structures. This means: - create a register layout struct that will hold offsets for registers - create a platform struct that will hold platform information (number of channels, indexes for different channels and pointer to layout struct) - convert specific macros that are platform dependent into platform variables This step is in fact a no-op, but allows the driver to be more flexible and for future enhancement including adding new platforms that are partly compatible with the current driver and differ slightly in register layout or capabilities for example.

If there are no channels defined in the devicetree, there's no point in probing the device. We were actually requesting a zero sized 'kmalloc' array but since we were not touching the ZERO_SIZE_PTR afterwards, nothing bad was actually happening. Hence this is not really a fix but rather an improvement. Reviewed-by:

The bindings file for this driver is defining the property as 'reg' but the driver was reading it with the 'num' name. The bindings actually had the 'num' property when added in commit ea52c212 ("dt-bindings: iio: dac: Add docs for AD5770R DAC") and then changed it to 'reg' in commit 2cf3818f ("dt-bindings: iio: dac: AD5570R fix bindings errors"). However, both these commits landed in v5.7 so the assumption is that either 'num' is not being used or if it is, the validations were not done. Anyways, if someone comes back yelling about this, we might just support both of the properties in the future. Not ideal, but that's life...

Commit b1fe0cf0 ("Input: delete MPU3050 driver") deletes the superseded MPU3050 driver and its corresponding config INPUT_MPU3050. The dependencies on the superseding driver in ./drivers/iio/gyro/Kconfig to ensure that the two drivers are not built into the same kernel is a dead dependency and not required anymore. So, remove those config dependencies on INPUT_MPU3050 for MPU3050_I2C. This issue was detected with ./scripts/checkkconfigsymbols.py. Signed-off-by:

The idea behind it, is that all devm_ calls in ST sensors are bound to the parent device object. However, the reference to that object is kept on both the st_sensor_data struct and the IIO object parent (indio_dev->dev.parent). This change only adds a bit consistency and uses the reference stored on indio_dev->dev.parent, to enforce the assumption that all ST sensors' devm_ calls are bound to the same reference as the one store on st_sensor_data.

At this point all ST driver remove functions do iio_device_unregister(). This change removes them from them and replaces all iio_device_register() with devm_iio_device_register(). This can be done in a single change relatively easy, since all these remove functions are define in st_sensors.h. Reviewed-by:

This change converts the st_sensors_power_enable() function to use devm_add_action_or_reset() handlers to register regulator_disable hooks for when the drivers get unloaded. The parent device of the IIO device object is used. This is based on the assumption that all other devm_ calls in the ST sensors use this reference. This makes the st_sensors_power_disable() un-needed. Removing this also changes unload order a bit, as all ST drivers would call st_sensors_power_disable() first and iio_device_unregister() after that. Reviewed-by:

This is based on the assumption that all other devm_ calls in the ST sensors use this reference. That makes the st_sensors_deallocate_trigger() function un-needed, so it can be removed. Reviewed-by:

Up until commit ea7e586b ("iio: st_sensors: move regulator retrieveal to core") only the ST pressure driver seems to have had any regulator disable. After that commit, the regulator handling was moved into the common st_sensors logic. In all instances of this regulator handling, the regulators were disabled before unregistering the IIO device. This can cause issues where the device would be powered down and still be available to userspace, allowing it to send invalid/garbage data. This change moves the st_sensors_power_disable() after the common probe functions. These common probe functions also handle unregistering the IIO device.
