Subject: [PATCH v2 4/5] ARM: dts: am437x/am33xx/omap/dm816x: Add gpmc dma channel
Date: Thu, 15 Oct 2015 12:37:27 -0500	[thread overview]
Message-ID: <1444930648-19313-5-git-send-email-fcooper@ti.com> (raw)
In-Reply-To: <1444930648-19313-1-git-send-email-fcooper@ti.com>

Add dma channel information to the gpmc. Although not enabled by
default this will allow prefetch-dma to be used.

Signed-off-by: Franklin S Cooper Jr <fcooper@ti.com>
