As mentioned in the cover letter this requires multi-PD support in
imx-pci to be implemented, specifically PATCH 3/4 of this series:

https://lore.kernel.org/patchwork/patch/996810/

Unless that also gets merged soon via pci I expect issues in linux-next.
The patch already has reviewed-by tags so "merging it soon" is not
unreasonable.

There is also an mxsfb dependency but that's already merged in
torvalds/master.
