Subject: [PATCH 0/7] mtd: rawnand: Convert drivers to use dma_request_chan()
Date: Thu, 27 Feb 2020 14:37:42 +0200 [thread overview]
Message-ID: <20200227123749.24064-1-peter.ujfalusi@ti.com> (raw)
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
