* SPEAr SMI
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : "st,spear600-smi"
|
||
|
|
- reg : Address range of the mtd chip
|
||
|
|
- #address-cells, #size-cells : Must be present if the device has sub-nodes
|
||
|
|
representing partitions.
|
||
|
|
- interrupt-parent: Should be the phandle for the interrupt controller
|
||
|
|
that services interrupts for this device
|
||
|
|
- interrupts: Should contain the STMMAC interrupts
|
||
|
|
- clock-rate : Functional clock rate of SMI in Hz
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- st,smi-fast-mode : Flash supports read in fast mode
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
smi: flash@fc000000 {
|
||
|
|

|
||
|
|
#address-cells = <1>;

reg = <0xfc000000 0x1000>;
|
||
|
|
interrupt-parent = <&vic1>;
|
||
|
|
interrupts = <12>;
|
||
|
|
clock-rate = <50000000>; /* 50MHz */
|
||
|
|
|
||
|
|
flash@f8000000 {
