we're usig 4 irq elements nowadays to accomodate the pmus for separate
clusters, see
https://git.kernel.org/cgit/linux/kernel/git/mmind/linux-rockchip.git/commit/?id=210bbd38bb88989ce19208f98e530ff0468f38bd
Same for the edp node.
Also, sadly the rockchip drm seems to need some tweaks still, as I wasn't
able to get any display output yet.
To make the vop at least compile I needed to forward-port

https://github.com/mmind/linux-rockchip/commit/0edb1f7e1ac77437a17d7966121ee6e10ab5db67
[full branch is https://github.com/mmind/linux-rockchip/commits/tmp/testing_20161109 ]
but I'm not sure if I did that correctly yet and am also still seeing
nothing on the display and get iommu errors when starting X11
