[RFC PATCH 00/11 V5] MXS: Add i.MX28 USB Host driver

[Russell King - ARM Linux]

Do you really need 138 messages (and counting) all threaded together
across the entire history of this patch set?  Please stop posting new
copies of your patch set as followups to the previous set.

Not only does it rob horizontal space for reading the subjects in the
index, but also it either buries your patches ages back or brings the
entire 138 messages to the front of mailboxes, depending on your sort
preferences.  Either way it makes threaded reading of the mailing list
really difficult.

Please stop this antisocial behaviour.  Thanks.
