1* SPEAr SMI
2
3Required properties:
4- compatible : "st,spear600-smi"
5- reg : Address range of the mtd chip
6- #address-cells, #size-cells : Must be present if the device has sub-nodes
7  representing partitions.
8- interrupts: Should contain the STMMAC interrupts
9- clock-rate : Functional clock rate of SMI in Hz
10
11Optional properties:
12- st,smi-fast-mode : Flash supports read in fast mode
13
14Example:
15
16	smi: flash@fc000000 {
17		compatible = "st,spear600-smi";
18		#address-cells = <1>;
19		#size-cells = <1>;
20		reg = <0xfc000000 0x1000>;
21		interrupt-parent = <&vic1>;
22		interrupts = <12>;
23		clock-rate = <50000000>;	/* 50MHz */
24
25		flash@f8000000 {
26			st,smi-fast-mode;
27			...
28		};
29	};
