Subject: [PATCH 1/2] dma: edma: Update caps->residue_granularity to match with reality
Date: Wed, 16 Jul 2014 15:29:20 +0300 [thread overview]
Message-ID: <1405513761-23739-2-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1405513761-23739-1-git-send-email-peter.ujfalusi@ti.com>
The edma can report accurate DMA position so update the residue_granularity
to DMA_RESIDUE_GRANULARITY_BURST.
