Subject: [PATCH v5 4/8] dmaengine: omap-dma: Use defines for dma channels and request count
Date: Thu, 9 Apr 2015 12:35:50 +0300	[thread overview]
Message-ID: <1428572154-3548-5-git-send-email-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <1428572154-3548-1-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.
