[PATCH v2 00/11] dma: pdma: some patches needed for PXA DT environments

[zonque@gmail.com (Daniel Mack)]

This is v2 of my series to add more features to the pdma driver.

Changes from v1 -> v2:

 - drop the two patches from Xiang Wang that are already applied to
   Vinod's next branch
 - add another patch to cleanup the unlocking path in lookup_phy(),
   as suggested by Ezequiel
 - provide an own xlate function rather than using
   of_dma_simple_xlate(), as suggested by Arnd


There's still an open topic with the DALGN flag, as Xiang Wang pointed
out. According to him, there's a chance we need an alternative way of
forcing the driver into byte-align mode, but that can still be done in
an additional patch later.


Thanks,
Daniel
