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 - 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>; };
