1 Renesas MSIOF spi controller
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-sh7724" (SH)
9 "renesas,msiof-r8a7790" (R-Car H2)
10 "renesas,msiof-r8a7791" (R-Car M2)
11 - reg : Offset and length of the register set for the device
12 - interrupt-parent : The phandle for the interrupt controller that
13 services interrupts for this device
14 - interrupts : Interrupt specifier
15 - #address-cells : Must be <1>
16 - #size-cells : Must be <0>
19 - clocks : Must contain a reference to the functional clock.
20 - num-cs : Total number of chip-selects (default is 1)
22 Optional properties, deprecated for soctype-specific bindings:
23 - renesas,tx-fifo-size : Overrides the default tx fifo size given in words
25 - renesas,rx-fifo-size : Overrides the default rx fifo size given in words
26 (default is 64, or 256 on R-Car H2 and M2)
28 Pinctrl properties might be needed, too. See
29 Documentation/devicetree/bindings/pinctrl/renesas,*.
