31 When compatible with a generic R-Car version, nodes
32 must list the SoC-specific version corresponding to
33 the platform first followed by the generic R-Car
36 When compatible with "renesas,rmobile-iic" it should
37 be the last compatibility string listed.
39 The r8a77990 (R-Car E3) and r8a774c0 (RZ/G2E)
40 controllers are not considered compatible with
41 "renesas,rcar-gen3-iic" or "renesas,rmobile-iic"
42 due to the absence of automatic transmission registers.
44 - reg : address start and address range size of device
45 - interrupts : interrupt of device
46 - clocks : clock for device
47 - #address-cells : should be <1>
48 - #size-cells : should be <0>
51 - clock-frequency : frequency of bus clock in Hz. Default 100kHz if unset.
52 - dmas : Must contain a list of two references to DMA
53 specifiers, one for transmission, and one for
55 - dma-names : Must contain a list of two DMA names, "tx" and "rx".
58 Pinctrl properties might be needed, too. See there.
