- interrupts: The interrupt number to the cpu. The interrupt specifier format
depends on the interrupt controller.
[PRELIMINARY: the dma channel allocation will change once there are
official DMA bindings]
- dmas : Two or more DMA channel specifiers following the convention outlined
in bindings/dma/dma.txt
- tx-dma-channel: The dma channel specifier for tx operations. The format of
the dma specifier depends on the dma controller.
- rx-dma-channel: The dma channel specifier for rx operations. The format of
the dma specifier depends on the dma controller.
- dma-names: Names for the dma channels. There must be at least one channel
named "tx" for transmit and named "rx" for receive.
