I don't see any of the issues resolved which I raised at v3. I think
Russell pointed that you do not have EEPROM and that some pins are
optional. You do not allow that.

Plus I don't see him being Cced but he had quite detailed look and
comments at your patchset, so *you are supposed to Cc* him.

I also do not see Rob's comments fully addressed.

Do not send next versions before resolving previous discusssion.

Please properly wrap your code according to Linux and DTS coding style
documents.
