* Mediatek UART APDMA Controller
|
|
|
|
Required properties:
|
|
- compatible should contain:
|
|
* "mediatek,mt2712-uart-dma" for MT2712 compatible APDMA
|
|
* "mediatek,mt6577-uart-dma" for MT6577 and all of the above
|
|
|
|
- reg: The base address of the APDMA register bank.
|
|
|
|
- interrupts: A single interrupt specifier.
|
|
|
|
- clocks : Must contain an entry for each entry in clock-names.
|
|
See ../clocks/clock-bindings.txt for details.
|
|
- clock-names: The APDMA clock for register accesses
|
|
|
|
Examples:
|
|
|
|
apdma: dma-controller@11000380 {
|
|
compatible = "mediatek,mt2712-uart-dma";
|
|
reg = <0 0x11000380 0 0x400>;
|

interrupts = <GIC_SPI 63 IRQ_TYPE_LEVEL_LOW>,
|
|
<GIC_SPI 64 IRQ_TYPE_LEVEL_LOW>,
|
|
<GIC_SPI 65 IRQ_TYPE_LEVEL_LOW>,
