1	NAND support for Marvell Orion SoC platforms
2	
3	Required properties:
4	- compatible : "marvell,orion-nand".
5	- reg : Base physical address of the NAND and length of memory mapped
6		region
7	
8	Optional 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	
15	The device tree may optionally contain sub-nodes describing partitions of the
16	address space. See partition.txt for more detail.
17	
18	Example:
19	
20	nand@f4000000 {
21		#address-cells = <1>;
22		#size-cells = <1>;
23		cle = <0>;
24		ale = <1>;
25		bank-width = <1>;
26		chip-delay = <25>;
27		compatible = "marvell,orion-nand";
28		reg = <0xf4000000 0x400>;
29	
30		partition@0 {
31			label = "u-boot";
32			reg = <0x0000000 0x100000>;
33			read-only;
34		};
35	
36		partition@100000 {
37			label = "uImage";
38			reg = <0x0100000 0x200000>;
39		};
40	
41		partition@300000 {
42			label = "dtb";
43			reg = <0x0300000 0x100000>;
44		};
45	
46		partition@400000 {
47			label = "root";
48			reg = <0x0400000 0x7d00000>;
49		};
50	};
