[PATCH 0/7] mtd: rawnand: Convert drivers to use dma_request_chan()

From: Peter Ujfalusi

Hi,

With dma_request_chan() drivers can know why the channel request failed and
depending on how they are implemented can handle the failure in a best effort,
either deferring or falling back to PIO mode.

Regards,
Peter
