Device tree configuration for Renesas RIIC driver
Required properties:
-- compatible : "renesas,riic-<soctype>". "renesas,riic-rz" as fallback
+- compatible :
+ "renesas,riic-r7s72100" if the device is a part of a R7S72100 SoC.
+ "renesas,riic-r7s9210" if the device is a part of a R7S9210 SoC.
+ "renesas,riic-rz" for a generic RZ/A compatible device.
- reg : address start and address range size of device
- interrupts : 8 interrupts (TEI, RI, TI, SPI, STI, NAKI, ALI, TMOI)
- clock-frequency : frequency of bus clock in Hz
