On one of our boards we use gpio-mux with iio-mux to read voltages using an ADC
from a few different channels, and on this board the input voltage needs some
time to stabilize after a switch of the mux.

This series add devicetree and driver support for this kind of hardware which
requries a settle time after muxing.

I have a board with the very same problem. And a similar solution, but you beat me with upstreaming. I've switched to your patchset.

Whole series
