Subject: [PATCH v2 1/5] mtd: nand: omap2: Support parsing dma channel information from DT
Date: Thu, 15 Oct 2015 12:37:24 -0500 [thread overview]
Message-ID: <1444930648-19313-2-git-send-email-fcooper@ti.com> (raw)
In-Reply-To: <1444930648-19313-1-git-send-email-fcooper@ti.com>
Switch from dma_request_channel to allow passing dma channel
information from DT rather than hardcoding a value.
