Subject: [RFC PATCH 4/4] ARM: at91/dt: sama5d2: add nand0 and nfc0 nodes
Date: Tue, 12 Jan 2016 15:33:43 +0100	[thread overview]
Message-ID: <1452609223-14790-5-git-send-email-romain.izard.pro@gmail.com> (raw)
In-Reply-To: <1452609223-14790-1-git-send-email-romain.izard.pro-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Both nodes are required to access NAND Flash memory. Additional
settings will be necessary at the board level to use it.

Signed-off-by: Romain Izard <romain.izard.pro-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
