I have tested it on zcu102 where I use gpio hogs for gt muxes.
gpio hogs are handled and setup only when gpio controller is probed.
Do we have a way how to say that controllers with gpio hogs should be
probed automatically?

Right now you are calling it in post_probe which make sense but on the
other hand if you find gpio hog in bind you should probe the whole
driver without asking for request.

Thanks,
