| 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"; |
| }; |
