No, I believe the gadget stack currently does not look at this at all while the host stack refuses to bind/load if it is not set to host. Whether or not this is a good idea and/or would need fixing at various other places remains to be seen I guess.
I think it is a bit strange to describe the USB otg port as "host" in the devicetree if it really works in peripheral mode.
No, on Colibri iMX7 one may really use it either in host or peripheral mode. This is especially important on the solo variant which has only that one single USB OTG port.
By the way, we don't see this issue with imx7s-warp.dts, nor imx7d- pico.dtsi.
Just to be crystal clear what we are talking about: On those two one may also use the USB OTG port either as host (e.g. doing usb start; ls usb 0:1 etc.) or peripheral (e.g. doing ums 0 mmc 0), right?
