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";
|
|
};
