Kernel-4.18.0-80.el8_spear_smi

• 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 {
    compatible = "st,spear600-smi";
    #address-cells = <1>;
    #size-cells = <1>;
    reg = <0xfc000000 0x1000>;
    interrupt-parent = <&vic1>;
    interrupts = <12>;
    clock-rate = <50000000>;    /* 50MHz */

    flash@f8000000 {
        st,smi-fast-mode;
        ...
    };
};
