That's unfortunate, especially given the bug with the clock polarity
(which, although I can tweak the register directly, it's not obvious
that changing the clk_pol initialisation is the correct solution.)

There's also another issue here: the lack of DRM prime support.  As
you have a separate GPU and separate VPU, you really need dmabuf
support implemented so that you can hand your scanout buffers/overlays
to other subsystems.
