1 UniPhier Media IO DMA controller
3 This works as an external DMA engine for SD/eMMC controllers etc.
4 found in UniPhier LD4, Pro4, sLD8 SoCs.
7 - compatible: should be "socionext,uniphier-mio-dmac".
8 - reg: offset and length of the register set for the device.
9 - interrupts: a list of interrupt specifiers associated with the DMA channels.
10 - clocks: a single clock specifier.
11 - #dma-cells: should be <1>. The single cell represents the channel index.
14 dmac: dma-controller@5a000000 {
15 compatible = "socionext,uniphier-mio-dmac";
16 reg = <0x5a000000 0x1000>;
17 interrupts = <0 68 4>, <0 68 4>, <0 69 4>, <0 70 4>,
18 <0 71 4>, <0 72 4>, <0 73 4>, <0 74 4>;
19 clocks = <&mio_clk 7>;
24 In the example above, "interrupts = <0 68 4>, <0 68 4>, ..." is not a typo.
25 The first two channels share a single interrupt line.
