1	Renesas MSIOF spi controller
2	
3	Required properties:
4	- compatible           : "renesas,msiof-<soctype>" for SoCs,
5				 "renesas,sh-msiof" for SuperH, or
6				 "renesas,sh-mobile-msiof" for SH Mobile series.
7				 Examples with soctypes are:
8				 "renesas,msiof-r8a7790" (R-Car H2)
9				 "renesas,msiof-r8a7791" (R-Car M2)
10	- reg                  : Offset and length of the register set for the device
11	- interrupt-parent     : The phandle for the interrupt controller that
12				 services interrupts for this device
13	- interrupts           : Interrupt specifier
14	- #address-cells       : Must be <1>
15	- #size-cells          : Must be <0>
16	
17	Optional properties:
18	- clocks               : Must contain a reference to the functional clock.
19	- num-cs               : Total number of chip-selects (default is 1)
20	
21	Optional properties, deprecated for soctype-specific bindings:
22	- renesas,tx-fifo-size : Overrides the default tx fifo size given in words
23				 (default is 64)
24	- renesas,rx-fifo-size : Overrides the default rx fifo size given in words
25				 (default is 64, or 256 on R-Car H2 and M2)
26	
27	Pinctrl properties might be needed, too.  See
28	Documentation/devicetree/bindings/pinctrl/renesas,*.

30	Example:
31	
32		msiof0: spi@e6e20000 {
33			compatible = "renesas,msiof-r8a7791";
34			reg = <0 0xe6e20000 0 0x0064>;
35			interrupts = <0 156 IRQ_TYPE_LEVEL_HIGH>;
36			clocks = <&mstp0_clks R8A7791_CLK_MSIOF0>;
37			#address-cells = <1>;
38			#size-cells = <0>;
39			status = "disabled";
