Renesas MSIOF spi controller
Required properties:
- compatible : "renesas,msiof-<soctype>" for SoCs,
"renesas,sh-msiof" for SuperH, or
"renesas,sh-mobile-msiof" for SH Mobile series.
Examples with soctypes are:
"renesas,msiof-r8a7790" (R-Car H2)
"renesas,msiof-r8a7791" (R-Car M2)
- 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>
Optional properties:
- clocks : Must contain a reference to the functional clock.
- num-cs : Total number of chip-selects (default is 1)
Optional properties, deprecated for soctype-specific bindings:
- renesas,tx-fifo-size : Overrides the default tx fifo size given in words
(default is 64)
- renesas,rx-fifo-size : Overrides the default rx fifo size given in words
(default is 64, or 256 on R-Car H2 and M2)
Pinctrl properties might be needed, too. See
Documentation/devicetree/bindings/pinctrl/renesas,*.
Example:
msiof0: spi@e6e20000 {
compatible = "renesas,msiof-r8a7791";
reg = <0 0xe6e20000 0 0x0064>;
interrupts = <0 156 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&mstp0_clks R8A7791_CLK_MSIOF0>;
#address-cells = <1>;
#size-cells = <0>;
status = "disabled";
};
