Subject: mtd: nand: Update driver to match new DT binding
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c2b74edf156ca60af26e87fdfce13025b4312857;p=u-boot.git

mtd: nand: Update driver to match new DT binding

New binding changed node name from flash@e1000000 to nand-controller@0,0
which should be reflected in the driver. Both names are supported for
backward compatibility.
