I did run dtbs_check on the binding and was > sooo happy to not find any panel errors in the pages of other dt errors > but till now didn't realize that there's also a dtbinding_check. dt_bindings_check is a sanity check on the bindings themselves. dtbs_check is using those bindings to check the device trees. dtbs_check used to have a dependency on dt_bindings_check, but it got removed recently.

It's not really what I meant though :) If it's needed then we should definitely have it, but we should document our expectations here: is it the input port ? output? in which case do we want to use it since it's optional, etc. Maxime _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
