You enable both VOPs below and the linux display subsystem should be able to select an appropriate VOP for output just fine on its own. So there should be no reason for capping the hdmi's connection to one of the vops. > + }; > +}; [...] > +&usb_host0_ehci { > + no-relinquish-port; This seems like an unused/undocumented property > + status = "okay"; > +}; [...] > +&vopl { > + status = "okay"; > + /* Don't use vopl for HDMI */ > + vopl_out: port { > + /delete-node/ endpoint@0; > + }; see comment at the hdmi node > +}; Thanks Heiko

Resolution-limitations and selecting a matching vop should be handled in the drm driver I'd think - but you'll need to talk to Mark Yao or some else knowledgable in graphics. The devicetree is about describing the _available_ hardware, not configuring how it is supposed to be used ;-) . Heiko
