-Required properties:
-- compatible should contain:
- * "mediatek,mt2712-uart-dma" for MT2712 compatible APDMA
- * "mediatek,mt6577-uart-dma" for MT6577 and all of the above
- * "mediatek,mt8516-uart-dma", "mediatek,mt6577" for MT8516 SoC
-
-- reg: The base address of the APDMA register bank.
-
-- interrupts: A single interrupt specifier.
- One interrupt per dma-requests, or 8 if no dma-requests property is present
-
-- dma-requests: The number of DMA channels
-
-- 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
