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>;
};
