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- interrupt-parent: Should be the phandle for the interrupt controller
9  that services interrupts for this device
10- interrupts: Should contain the STMMAC interrupts
11- clock-rate : Functional clock rate of SMI in Hz
12
13Optional properties:
14- st,smi-fast-mode : Flash supports read in fast mode

16Example:
17
18	smi: flash@fc000000 {
19		compatible = "st,spear600-smi";
20		#address-cells = <1>;
21		#size-cells = <1>;
22		reg = <0xfc000000 0x1000>;
23		interrupt-parent = <&vic1>;
24		interrupts = <12>;
25		clock-rate = <50000000>;	/* 50MHz */
26
27		flash@f8000000 {
28			st,smi-fast-mode;
29			...
30		};
31	};
