1 | * SPEAr SMI | ||
2 | |||
3 | Required 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 | |||
13 | Optional properties: | ||
14 | - st,smi-fast-mode : Flash supports read in fast mode | ||
15 | |||
16 | Example: | ||

18 | smi: flash@fc000000 { | ||
19 | compatible = "st,spear600-smi"; | ||
20 | #address-cells = <1>; | ||
21 | #size-cells = <1>; | ||

23 | interrupt-parent = <&vic1>; | ||
24 | interrupts = <12>; | ||
25 | clock-rate = <50000000>; /* 50MHz */ | ||
