* iio: Add IIO_DELTA_VELOCITY channel typeRamona Bolboaca2023-09-124-0/+27
| | | | | | | | | | | | | | | | | | | The delta velocity is defined as a piece-wise integration of acceleration data. The delta velocity represents the linear velocity change between two consecutive measurements and it is measured in m / s (meters per second). In order to track the total linear velocity change during a desired period of time, simply sum-up the delta velocity samples acquired during that time. IIO currently does not offer a suitable channel type for this type of measurements hence this patch adds it.

Also replace devm_regulator_get() and regulator_enable() with devm_regulator_get_enable() helper and remove regulator_disable(). Replace iio_device_register() with devm_iio_device_register() and remove iio_device_unregister(). And st->reg is not used anymore, so remove it. As Jonathan pointed out, couple of things that are wrong: 1) The device is powered down 'before' we unregister it with the subsystem and as such userspace interfaces are still exposed which probably won't do the right thing if the chip is powered down. 2) This isn't done in the error paths in probe. To solve this problem, register a new callback adf4350_power_down() with devm_add_action_or_reset(), to enable software power down in both error and device detach path. So the remove function can be removed. Remove spi_set_drvdata() from the probe function, since spi_get_drvdata() is not used anymore.
