[PATCH (v4) 1/2] mtd: brcmnand: Add brcm,bcm63268-nand device tree binding

[Simon Arlott]

Add device tree binding for NAND on the BCM63268.

The BCM63268 has a NAND interrupt register with combined status and enable
registers.

The existing two bindings use brcm,nand-<soc>, but I've changed this one.
