Thanks for your patch!

I think it would be better to get rid of this macro, as
of_device_get_match_data()
walks the rcar_thermal_dt_ids[] over and over again.
Instead, you can store a pointer to struct rcar_thermal_chip in struct
rcar_thermal_priv in rcar_thermal_probe().

This cast not needed.

Why 2? Your DT patch has 3 interrupts, which matches the datasheet.
