1 Synopsys DesignWare AXI DMA Controller
4 - compatible: "snps,axi-dma-1.01a"
5 - reg: Address range of the DMAC registers. This should include
6 all of the per-channel registers.
7 - interrupt: Should contain the DMAC interrupt number.
8 - dma-channels: Number of channels supported by hardware.
9 - snps,dma-masters: Number of AXI masters supported by the hardware.
10 - snps,data-width: Maximum AXI data width supported by hardware.
11 (0 - 8bits, 1 - 16bits, 2 - 32bits, ..., 6 - 512bits)
12 - snps,priority: Priority of channel. Array size is equal to the number of
13 dma-channels. Priority value must be programmed within [0:dma-channels-1]
14 range. (0 - minimum priority)
15 - snps,block-size: Maximum block size supported by the controller channel.
16 Array size is equal to the number of dma-channels.
19 - snps,axi-max-burst-len: Restrict master AXI burst length by value specified
20 in this property. If this property is missing the maximum AXI burst length
21 supported by DMAC is used. [1:256]
