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

[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

Pls allow me to have a look at it and bring up with ChromeOs, the 
upstream maybe miss some patches for upstream. (DRM or IOMMU or ....)
I will resend the other patches if  I bring up and show display with 
upstream  on
