This is targeting serial subsystem, thus it would be nice to get and Ack from Vinod first. Moreover, the series depends on [1] that is now under review. That's why I asked Vinod to create immutable tag / branch for the [1] and the dependants (at least one more, which is sata_dwc_460ex). The series can be reached in the branch located at [2].
