Right. But I think we've now established that what is described in the
device tree is the state the pins should be in after the function has
been called, eg. only the reduction matters, and any interim states
would just be a byproduct of storing the state in the configs list.

Right. But I think we've now established that what is described in the
device tree is the state the pins should be in after the function has
been called, eg. only the reduction matters, and any interim states
would just be a byproduct of storing the state in the configs list.
