29	When compatible with the generic version, nodes must list the
30	SoC-specific version corresponding to the platform first followed
31	by the generic version.
32
33- reg: physical base address of the controller and length of memory mapped
34  region.
35- interrupts: interrupt specifier.
36
37Optional properties:
38- clock-frequency: desired I2C bus clock frequency in Hz. The absence of this
39  property indicates the default frequency 100 kHz.
40- clocks: clock specifier.
41- dmas: Must contain a list of two references to DMA specifiers, one for
42  transmission, and one for reception.
43- dma-names: Must contain a list of two DMA names, "tx" and "rx".
