Subject: [PATCH 1/3] dt-bindings: mtd: sunxi: Add new compatible
Date: Thu, 4 Apr 2019 18:21:09 +0200 [thread overview]
Message-ID: <20190404162111.22618-2-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20190404162111.22618-1-miquel.raynal@bootlin.com>
The A33 NAND controller is slightly different than the A10+ ones,
eg. DMA handling is a bit different and a few register offsets
changed.
Introduce a new compatible to represent this version of the IP.
Also append '-controller' to the new compatible (which is required for
new compatibles) as this is describing a NAND controller and not a
NAND chip.
