I think leave it a while longer - the series emails were accepted by
gabe.freedesktop.org at 09:51 UTC, maybe it's still thinking about

http://git.armlinux.org.uk/cgit/linux-arm.git/log/?h=drm-tda998x-devel

contains very similar patches, but based on 4.20.  The series I posted
were those patches rebased on the linux-drm drm-next branch - and there
were some minor conflicts.
