Kernel-4.18.0-80.el8_spi-armada-3700

• Marvell Armada 3700 SPI Controller

Required Properties:

• compatible: should be “marvell,armada-3700-spi”
• reg: physical base address of the controller and length of memory mapped

   region.
  

• interrupts: The interrupt number. The interrupt specifier format depends on

      the interrupt controller and of its driver.
  

• clocks: Must contain the clock source, usually from the North Bridge clocks.
• num-cs: The number of chip selects that is supported by this SPI Controller
• #address-cells: should be 1.
• #size-cells: should be 0.

Example:

spi0: spi@10600 {
    compatible = "marvell,armada-3700-spi";
    #address-cells = <1>;
    #size-cells = <0>;
    reg = <0x10600 0x5d>;
    clocks = <&nb_perih_clk 7>;
    interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
    num-cs = <4>;
};
