PL330 DMA Controller
A phandle to the DMA controller plus "channel" integer cell specifying
channel to be used for data transfer
Example for pl330 DMA Controller
pl330: pl330@48300000 {
compatible = "arm,dma-pl330";
...
dma-channels = <8>;
#dma-cells = <1>;
};
If PCIe EP client uses channel 0 for Tx DMA and channel 1 for Rx DMA
pcie0_ep: pcie@4e100000 {
compatible = "brcm,iproc-pcie-ep";
...
dmas = <&pl330 0>, <&pl330 1>;
dma-names = "txdma", "rxdma";
};
compatible: "arm,dma-pl330"
