1Renesas HSPI. 2 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> 12 13Pinctrl properties might be needed, too. See 14Documentation/devicetree/bindings/pinctrl/renesas,*. 15 16Example: 17 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 }; 26 27
