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.
33 - reg: physical base address of the controller and length of memory mapped
35 - interrupts: interrupt specifier.
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".
45 - i2c-scl-falling-time-ns: see i2c.txt
46 - i2c-scl-internal-delay-ns: see i2c.txt
47 - i2c-scl-rising-time-ns: see i2c.txt
