Hi Sam, Thanks for your quick review, and sorry for the error in my patch. I thought my toolchain was properly configured, but it wasn't and I missed an include: #include <drm/drm_bridge.h> +#include <drm/drm_of.h> #include <drm/drm_panel.h> I apologize for the mistake. > From the documentation of drm_of_find_panel_or_bridge(): > > * This function is deprecated and should not be used in new drivers.

"devm_drm_of_get_bridge" returns the bridge and I didn't find a way to access the panel from it... But as I mentioned, I probably overlooked the required function or pointer. Thanks again for your review, Jose
