| Device tree configuration for Renesas RIIC driver |
| |
| Required properties: |
| - compatible : "renesas,riic-<soctype>". "renesas,riic-rz" as fallback |
| - reg : address start and address range size of device |
| - interrupts : 8 interrupts (TEI, RI, TI, SPI, STI, NAKI, ALI, TMOI) |
| - clock-frequency : frequency of bus clock in Hz |
| - #address-cells : should be <1> |
| - #size-cells : should be <0> |
| |
| Pinctrl properties might be needed, too. See there. |
| |
| Example: |
| |
| i2c0: i2c@fcfee000 { |
| compatible = "renesas,riic-r7s72100", "renesas,riic-rz"; |
| reg = <0xfcfee000 0x44>; |
| interrupts = <0 157 IRQ_TYPE_LEVEL_HIGH>, |
| <0 158 IRQ_TYPE_EDGE_RISING>, |
| <0 159 IRQ_TYPE_EDGE_RISING>, |
| <0 160 IRQ_TYPE_LEVEL_HIGH>, |
| <0 161 IRQ_TYPE_LEVEL_HIGH>, |
| <0 162 IRQ_TYPE_LEVEL_HIGH>, |
| <0 163 IRQ_TYPE_LEVEL_HIGH>, |
| <0 164 IRQ_TYPE_LEVEL_HIGH>; |
| clock-frequency = <100000>; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| }; |
