- #dma-cells: must be 2: the first integer is a terminal number, to which this
slave is connected, the second one is flags. Flags is a bitmask
with the following bits defined:
Optional properties:
- max-burst-mem-read: limit burst size for memory reads
(DMA_MEM_TO_MEM/DMA_MEM_TO_DEV) to this value, specified in bytes, rather
than using the maximum burst size allowed by the hardware's buffer size.
- max-burst-mem-write: limit burst size for memory writes
(DMA_DEV_TO_MEM/DMA_MEM_TO_MEM) to this value, specified in bytes, rather
than using the maximum burst size allowed by the hardware's buffer size.
If both max-burst-mem-read and max-burst-mem-write are set, DMA_MEM_TO_MEM
will use the lower value.
You can use dma-channels and dma-requests as described in dma.txt, although they
won't be used, this information is derived from the compatibility string.
