1	Device tree configuration for Renesas RIIC driver
2	
3	Required properties:
4	- compatible      : "renesas,riic-<soctype>". "renesas,riic-rz" as fallback
5	- reg             : address start and address range size of device
6	- interrupts      : 8 interrupts (TEI, RI, TI, SPI, STI, NAKI, ALI, TMOI)
7	- clock-frequency : frequency of bus clock in Hz
8	- #address-cells  : should be <1>
9	- #size-cells     : should be <0>
10	
11	Pinctrl properties might be needed, too. See there.

15		i2c0: i2c@fcfee000 {
