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. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> --- Changes in v2: * Removed the statement introduced with the new compatible.
