Hi Vinod,

A few people have been asking me if getting device-tree support for DMA
engine is plan for record for v3.8. I know that you were working through
implementing a common interface and so I wanted to check how that is
going. Do you have any insight to when device-tree support may get added?

Cheers
Jon
