Against which tree is this series?

>From patch 1, I derived it's against drm-misc
(git://anongit.freedesktop.org/drm-intel#topic/drm-misc), but later patches
have other requirements.
E.g. patch 13 assumes DRM_RCAR_DU has a dependency on OF, but that's nowhere
to be found in -next.
It is in git://linuxtv.org/pinchartl/media#vsp1-kms-gen3-20150909.2, but that
conflicts badly with your R-Car Gen3 VSP series.

Thanks!
