1Device tree configuration for Renesas RIIC driver
2
3Required properties:
4- compatible :
5 "renesas,riic-r7s72100" if the device is a part of a R7S72100 SoC.
6 "renesas,riic-r7s9210" if the device is a part of a R7S9210 SoC.
7 "renesas,riic-rz" for a generic RZ/A compatible device.
8- reg : address start and address range size of device
9- interrupts : 8 interrupts (TEI, RI, TI, SPI, STI, NAKI, ALI, TMOI)
10- clock-frequency : frequency of bus clock in Hz
11- #address-cells : should be <1>
12- #size-cells : should be <0>
13
14Pinctrl properties might be needed, too. See there.

16Example:

18 i2c0: i2c@fcfee000 {
19 compatible = "renesas,riic-r7s72100", "renesas,riic-rz";
20 reg = <0xfcfee000 0x44>;
21 interrupts = <0 157 IRQ_TYPE_LEVEL_HIGH>,
22 <0 158 IRQ_TYPE_EDGE_RISING>,
23 <0 159 IRQ_TYPE_EDGE_RISING>,
24 <0 160 IRQ_TYPE_LEVEL_HIGH>,
25 <0 161 IRQ_TYPE_LEVEL_HIGH>,
26 <0 162 IRQ_TYPE_LEVEL_HIGH>,
27 <0 163 IRQ_TYPE_LEVEL_HIGH>,
28 <0 164 IRQ_TYPE_LEVEL_HIGH>;
29 clock-frequency = <100000>;
30 #address-cells = <1>;
31 #size-cells = <0>;
