Hi Matt,

Do you know when the dt binding patch will be applied to
the drm-misc/for-linux-next tree?

I applied the dts patch but it is creating a warning in next right now.
If the binding won't show up soon in drm-misc, then I'll remove this dts
patch from next as dtbs_check is now failing in next. I can add it back
once the binding makes it to next.

Thanks,
Drew
