Hi All,
This series adds I3C node to RZ/V2N and RZ/V2H(P) SoC DTSI files.
I3C was tested on RZ/V2H(P) and RZ/V2N EVKs using P3T1085UK Arduino
Shield Evaluation Board [0].
Disable I2C2 on PMOD connector CN6 and enable I3C.
Connect EVK TO P3T1085UK Arduino Shield Evaluation Board
P3T1085UK <-> EVK PMOD CN6
- J13[1] to CN6[3] (I3C_SCL)
- J13[2] to CN6[4] (I3C_SDA)
- J13[4] to CN6[5] (GND)
- J9[7] to CN6[11] (GND)
- J9[9] to CN6[6] (3.3V)
On P3T1085UK,
- JP2 pin1 to pin2 (I3C_SDA)
- JP3 pin1 to pin2 (I3C_SCL)
- JP1 pin2 to pin3 (VDD 3V3)

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments.
