Hrrrum; I think this is a good idea, but I'm not thrilled with the
approach.  Here are my concerns:

- Determining that linux,stdout-path points to a PSC should should be
done in common code.  It's useful for all 5200 boards, not just the
Efika.  (However, if 'failsafe' processing is efika specific, then it
can stay in efika.c).  This might be best done within the PSC driver
itself, but I'm not sure.
- Recognizing a psc node should be done by inspecting the compatible
property, not by device_type and model properties.

Thanks,
g.
