Describe the bug

By making use of the i2c-sensor overlay for a bme680, the iio subsystem creates files in /sys for the sensor's outputs, which is lovely... but neglects the entire kernel-side infrastructure for collecting samples in ring buffers. The bme680 does not, itself, export any triggers for this machinery, so it would be nice to have software-defined triggers available. Specifically, I think that means setting...

CONFIG_IIO_SW_TRIGGER=m
CONFIG_IIO_HRTIMER_TRIGGER=m
CONFIG_IIO_INTERRUPT_TRIGGER=m
CONFIG_IIO_SYSFS_TRIGGER=m

Steps to reproduce the behaviour

Enable the i2c-sensor overlay for a bme680 and observe that iio_info says "No trigger on this device" and enumerates no other triggers on the machine.

Device (s)

Apologies - this is one of a number of issues from that time that have had no attention.

All the current branches should now include the necessary config settings. so future builds will ship with the required modules.

I've used these triggers in the latest Bullseye OS. I suppose this issue can be closed.
