This is up for discussion, more or less. Here's how I handled it until now:

RSVD -- registers marked as reverved in the datasheet

NANA -- do default available / mentioned in the datasheet

MISC -- random other values which cannot be expressed in numbers
        (e.g. "Bits 0 and 1 depend on the state of xyz, rest is 0"; in this
         case the default could be 0x03 or 0x00, we don't know. Thus MISC.)

CR 07 is debatable anyway. There's no real value in listing it at all,
IMO. Maybe we should just drop it from all listings? Comments?

Revision IDs (which can change from chip to chip) should be NANA, at
least that's how I handle them usually.

Good candidate for MISC, yes.

Hm, neither solution is good for this case, IMO. But we have to choose
one of them. I don't care which. Opinions?

Yes. But its unlikely that they're (very) different if they're
documented in the same datasheet. I'll check later.

I was about to commit, but noticed that you forgot to add a
Signed-off-by line, see 
Please repost with a Signed-off-by.

No need to rediff btw, we can adapt the patch to (smaller) changes
right before committing.
