[Feature request]: Support selecting specific IIO device

[justinlovinger]

Please describe your feature request

Currently, als.iio.path takes a directory of IIO devices and checks all of them. That makes sense as a default behavior, but there should be an option to specify a specific IIO device by giving the path to a specific IIO device.

For context, I have a device with more than one IIO light sensor, and there is currently no way to specify which one to use.

Makes sense - this could be where the "name" could be useful :) The reason for the current behavior is simply that the paths are not stable, after reboot you get a different full path - so one can't rely on paths themselves.

Ah. I didn't know the paths weren't stable. In my case, both light sensors have the same name, so even specifying a name wouldn't distinguish between them.

Let me know if you stumble upon some good way to uniquely identify a sensor, I think it's a good idea, we just need to find a nice approach to handle this.
