Yes it is and doable and you find this at [1], would need a rebase though.

It worked fine for me on Rb3 and db410c where we had HDMI connector. I don't have a panel device to test and Bjorn tried to help out with a bit of testing. This didn't work on the laptop, that is why I haven't posted it yet.
This has conversion of msm driver and bridge drivers lt9611, adv7511 and ti-sn65dsi86.
