It should also enter retention dynamically.

Better making it modular and let mmc guys dig on it. What do you need to make it more pm friendly? Madhu recently traded work arounds in one of our MMC trees. A rest of command line was used instead of toggle of idle handshakes. Hardware designers did confirm it being needed. I'll forward a version. Regards, Richard W.
