1Device tree configuration for Renesas RIIC driver
2
3Required 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
11Pinctrl properties might be needed, too. See there.
