Kernel-4.18.0-80.el8_spi-bcm63xx-hsspi

Binding for Broadcom BCM6328 High Speed SPI controller

Required properties:

• compatible: must contain of “brcm,bcm6328-hsspi”.
• reg: Base address and size of the controllers memory area.
• interrupts: Interrupt for the SPI block.
• clocks: phandles of the SPI clock and the PLL clock.
• clock-names: must be “hsspi”, “pll”.
• #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@10001000 {
    compatible = "brcm,bcm6328-hsspi";
    reg = <0x10001000 0x600>;

    interrupts = <29>;

    clocks = <&clkctl 9>, <&hsspi_pll>;
    clock-names = "hsspi", "pll";

    num-cs = <2>;

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