I just checked it: despite it looks like we could use the decoder and
encoder separately
(separate clocks for decoder / encoder) the VPU block won't work (SoC
crashes),
if not all 4 clocks are enabled for neither decoding nor encoding.
I'd prefer the other way also, but it seems not possible.
Alex.
