Normally once the driver-maintainer has applied binding + driver change, I also pick up the devicetree shortly change after that. And in most cases the driver change will be in -next the next day, and the dts change as well or 1-2 days later. If a CI bot complains, one then goes looking if something went wrong :-) .

I guess that might be a nice way to go, as then the main board dts doesn't has to wait for the drm changes to be finalized :-) Heiko
