Subject: [PATCH v3 5/5] ARM: at91/dt: sama5d2: add nand0 and nfc0 nodes
Date: Mon,  1 Feb 2016 11:26:00 +0100	[thread overview]
Message-ID: <1454322360-8666-6-git-send-email-romain.izard.pro@gmail.com> (raw)
In-Reply-To: <1454322360-8666-1-git-send-email-romain.izard.pro@gmail.com>

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@gmail.com>

v3: No change
v2: Fix device address, hexadecimal with minuscules
