Kernel-4.18.0-80.el8_sh-hspi

Renesas HSPI.

Required properties:

• compatible : “renesas,hspi-“, “renesas,hspi” as fallback.

         Examples with soctypes are:
           - "renesas,hspi-r8a7778" (R-Car M1)
           - "renesas,hspi-r8a7779" (R-Car H1)
  

• reg : Offset and length of the register set for the device
• interrupt-parent : The phandle for the interrupt controller that

         services interrupts for this device
  

• interrupts : Interrupt specifier
• #address-cells : Must be <1>
• #size-cells : Must be <0>

Pinctrl properties might be needed, too. See
Documentation/devicetree/bindings/pinctrl/renesas,*.

Example:

hspi0: spi@fffc7000 {
    compatible = "renesas,hspi-r8a7778", "renesas,hspi";
    reg = <0xfffc7000 0x18>;
    interrupt-parent = <&gic>;
    interrupts = <0 63 IRQ_TYPE_LEVEL_HIGH>;
    #address-cells = <1>;
    #size-cells = <0>;
};
