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