| Device tree configuration for Renesas IIC (sh_mobile) driver |
| |
| Required properties: |
| - compatible : "renesas,iic-<soctype>". "renesas,rmobile-iic" as fallback |
| - reg : address start and address range size of device |
| - interrupts : interrupt of device |
| - clocks : clock for device |
| - #address-cells : should be <1> |
| - #size-cells : should be <0> |
| |
| Optional properties: |
| - clock-frequency : frequency of bus clock in Hz. Default 100kHz if unset. |
| |
| Pinctrl properties might be needed, too. See there. |
| |
| Example: |
| |
| iic0: i2c@e6500000 { |
| compatible = "renesas,iic-r8a7790", "renesas,rmobile-iic"; |
| reg = <0 0xe6500000 0 0x425>; |
| interrupts = <0 174 IRQ_TYPE_LEVEL_HIGH>; |
| clocks = <&mstp3_clks R8A7790_CLK_IIC0>; |
| clock-frequency = <400000>; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| }; |
