These should be in the omap3.dtsi file and not nested but separate. I'm almost
certain that these are completely independent hardware modules and this
means they can live their own PM life independently.

So can you please do a minimal patch for omap3.dtsi that just sets up
the standard resources separately for both modules the same way we have
for other hardware modules in omap3.dtsi do?

One of them should be called ssi, no idea what the other module name should
be as those register ranges show up as reserved in the docs I have.

The other binding pieces can be added later on as they get are ready.
