Subject: [PATCH 3/6] dmaengine: omap-dma: Use defines for dma channels and request count
Date: Tue, 24 Feb 2015 16:21:20 +0200 [thread overview]
Message-ID: <1424787683-19151-4-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1424787683-19151-1-git-send-email-peter.ujfalusi@ti.com>
Instead of magic numbers in the code, use define for number of logical DMA
channels and DMA requests.
