1 MOXA ART DMA Controller
7 - compatible : Must be "moxa,moxart-dma"
8 - reg : Should contain registers location and length
9 - interrupts : Should contain an interrupt-specifier for the sole
10 interrupt generated by the device
11 - #dma-cells : Should be 1, a single cell holding a line request number
16 compatible = "moxa,moxart-dma";
17 reg = <0x90500080 0x40>;
25 DMA clients connected to the MOXA ART DMA controller must use the format
26 described in the dma.txt file, using a two-cell specifier for each channel:
27 a phandle plus one integer cells.
28 The two cells in order are:
30 1. A phandle pointing to the DMA controller.
31 2. Peripheral identifier for the hardware handshaking interface.
34 Use specific request line passing from dma
35 For example, MMC request line is 5
37 sdhci: sdhci@98e00000 {
38 compatible = "moxa,moxart-sdhci";
39 reg = <0x98e00000 0x5C>;
44 dma-names = "tx", "rx";
