Subject: [PATCH v2 5/5] ARM: OMAP2+: Update GPMC and NAND DT binding documentation
Date: Thu, 15 Oct 2015 12:37:28 -0500	[thread overview]
Message-ID: <1444930648-19313-6-git-send-email-fcooper@ti.com> (raw)
In-Reply-To: <1444930648-19313-1-git-send-email-fcooper@ti.com>

Add additional details to the GPMC NAND documentation to clarify
what is needed to enable NAND DMA prefetch.

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