  that services interrupts for this device
• interrupt: Should contain the CF interrupt number
• clock-frequency: Interface clock rate, in Hz, one of

   25000000
   33000000

Optional properties:

• arasan,broken-udma: if present, UDMA mode is unusable
• arasan,broken-mwdma: if present, MWDMA mode is unusable
• arasan,broken-pio: if present, PIO mode is unusable

Example:

cf@fc000000 {
    compatible = "arasan,cf-spear1340";
    reg = <0xfc000000 0x1000>;
    interrupt-parent = <&vic1>;
