Kernel-4.18.0-80.el8_spi-bcm63xx

Binding for Broadcom BCM6348/BCM6358 SPI controller

Required properties:

• compatible: must contain one of “brcm,bcm6348-spi”, “brcm,bcm6358-spi”.
• reg: Base address and size of the controllers memory area.
• interrupts: Interrupt for the SPI block.
• clocks: phandle of the SPI clock.
• clock-names: has to be “spi”.
• #address-cells: <1>, as required by generic SPI binding.
• #size-cells: <0>, also as required by generic SPI binding.

Optional properties:

• num-cs: some controllers have less than 8 cs signals. Defaults to 8
  if absent.

Child nodes as per the generic SPI binding.

Example:

spi@10000800 {
    compatible = "brcm,bcm6368-spi", "brcm,bcm6358-spi";
    reg = <0x10000800 0x70c>;

    interrupts = <1>;

    clocks = <&clkctl 9>;
    clock-names = "spi";

    num-cs = <5>;

    #address-cells = <1>;
    #size-cells = <0>;
};
