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 };
