1 * Spreadtrum DMA controller
3 This binding follows the generic DMA bindings defined in dma.txt.
6 - compatible: Should be "sprd,sc9860-dma".
7 - reg: Should contain DMA registers location and length.
8 - interrupts: Should contain one interrupt shared by all channel.
9 - #dma-cells: must be <1>. Used to represent the number of integer
11 - #dma-channels : Number of DMA channels supported. Should be 32.
12 - clock-names: Should contain the clock of the DMA controller.
13 - clocks: Should contain a clock specifier for each entry in clock-names.
17 Controller:
18 apdma: dma-controller@20100000 {
19 	compatible = "sprd,sc9860-dma";
22 	#dma-cells = <1>;
23 	#dma-channels = <32>;
24 	clock-names = "enable";
30 DMA clients connected to the Spreadtrum DMA controller must use the format
31 described in the dma.txt file, using a two-cell specifier for each channel.
33 1. A phandle pointing to the DMA controller.
38 	dma-names = "rx_chn", "tx_chn";
