Subject: [PATCH v4 2/5] dt-bindings: atmel_nand: Reword the documentation
Date: Wed, 10 Feb 2016 10:56:24 +0100 [thread overview]
Message-ID: <1455098187-9442-3-git-send-email-romain.izard.pro@gmail.com> (raw)
In-Reply-To: <1455098187-9442-1-git-send-email-romain.izard.pro-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
Do not mention which chips supporting the PMECC controller, as it a
duplicate of the information in the chips' device trees.
Use common terms when describing the sub-node for the NAND Flash
controller.
