   3 Required 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 - interrupt-parent : The phandle for the interrupt controller that
  10                      services interrupts for this device
  11 - interrupts       : Interrupt specifier
  12 - #address-cells   : Must be <1>
  13 - #size-cells      : Must be <0>
  14
  15 Pinctrl properties might be needed, too.  See
  16 Documentation/devicetree/bindings/pinctrl/renesas,*.

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