3Required properties:
4- compatible : "renesas,hspi-<soctype>", "renesas,hspi" as fallback.
5 Examples with soctypes are:
6 - "renesas,hspi-r8a7778" (R-Car M1)
7 - "renesas,hspi-r8a7779" (R-Car H1)
8- reg : Offset and length of the register set for the device
9- interrupts : Interrupt specifier
10- #address-cells : Must be <1>
11- #size-cells : Must be <0>

13Pinctrl properties might be needed, too. See
14Documentation/devicetree/bindings/pinctrl/renesas,*.

18 hspi0: spi@fffc7000 {
19 compatible = "renesas,hspi-r8a7778", "renesas,hspi";
20 reg = <0xfffc7000 0x18>;
21 interrupt-parent = <&gic>;
22 interrupts = <0 63 IRQ_TYPE_LEVEL_HIGH>;
23 #address-cells = <1>;
24 #size-cells = <0>;
25 };
