Subject: [PATCH v1 5/5] ARM: at91/dt: sama5d2: add nand0 and nfc0 nodes
Date: Wed, 13 Jan 2016 17:34:17 +0100	[thread overview]
Message-ID: <1452702857-2240-6-git-send-email-romain.izard.pro@gmail.com> (raw)
In-Reply-To: <1452702857-2240-1-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.
