I've tested this series with the DSI0 output and it works. Nice! No
need for my DSI0 patch for the MT8395 anymore.
But I can't get it to work with the DisplayPort output, that is the
dp_intf1/dp_tx interface. I don' know how the pipeline have to look
like. The functional spec seems to be ambiguous on this. The text
seem to refer to the second vdosys but there is also a diagram where
you can use the first vdosys and dsc0. If you have any pointers for
me, I'm all ears :)
