-* 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>;
