   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:
  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         };
