19 When compatible with the generic version, nodes must list the
20 SoC-specific version corresponding to the platform first followed
21 by the generic version.
23 - reg: physical base address of the controller and length of memory mapped
25 - interrupts: interrupt specifier.
28 - clock-frequency: desired I2C bus clock frequency in Hz. The absence of this
29 property indicates the default frequency 100 kHz.
30 - clocks: clock specifier.
31 - dmas: Must contain a list of two references to DMA specifiers, one for
32 transmission, and one for reception.
33 - dma-names: Must contain a list of two DMA names, "tx" and "rx".
35 - i2c-scl-falling-time-ns: see i2c.txt
36 - i2c-scl-internal-delay-ns: see i2c.txt
37 - i2c-scl-rising-time-ns: see i2c.txt
