Thanks for the reply Konstantin.  Does that mean you have the overlay patch applied to your kernel tree?

An alternative design that I am considering is having two complete device trees in a fit image, and u-boot reads the gpios to pick the correct dtb for linux.  Did you consider a design like that and if so, was there anything specific that sent you in the direction of overlays?
