These three are required, not optimal?

This is normally considered optional. Why require it?

This should be SoC specific, or also have an SoC specific string.

Is this common or vendor specific. The former should refer to a common 
doc. The latter should have a vendor prefix. I'd think the former makes 
sense here.

But then why do you need this and max-frame-size?
