Subject: [PATCH v2 1/3] dt-bindings: mtd: rzn1: Describe Renesas RZ/N1 NAND controller
Date: Fri, 26 Nov 2021 15:06:23 +0100 [thread overview]
Message-ID: <20211126140625.351697-2-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20211126140625.351697-1-miquel.raynal@bootlin.com>
Add a Yaml description for this Renesas NAND controller bindings.
Provide a family-specific "rzn1" compatible and a more specific
"r9a06g032" one.
