Renesas HSPI.
Required properties:
- compatible : "renesas,hspi-<soctype>", "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>;
status = "disabled";
};
