1NAND support for Marvell Orion SoC platforms
2
3Required properties:
4- compatible : "marvell,orion-nand".
5- reg : Base physical address of the NAND and length of memory mapped
6	region
7
8Optional properties:
9- cle : Address line number connected to CLE. Default is 0
10- ale : Address line number connected to ALE. Default is 1
11- bank-width : Width in bytes of the device. Default is 1
12- chip-delay : Chip dependent delay for transferring data from array to read
13               registers in usecs
14
15The device tree may optionally contain sub-nodes describing partitions of the
16address space. See mtd.yaml for more detail.
