In any case I would like to ask Bryan to do independent test. 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. On the other hand Vinod proposed to take it through dma-slave tree. Greg? 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) can use it. The series can be reached in the branch located at [2].
