-MediaTek High-Speed DMA Controller
-==================================
-
-This device follows the generic DMA bindings defined in dma/dma.txt.
-
-Required properties:
-
-- compatible:	Must be one of
-		  "mediatek,mt7622-hsdma": for MT7622 SoC
-		  "mediatek,mt7623-hsdma": for MT7623 SoC
-- reg:		Should contain the register's base address and length.
-- interrupts:	Should contain a reference to the interrupt used by this
-		device.
-- clocks:	Should be the clock specifiers corresponding to the entry in
-		clock-names property.
-- clock-names:	Should contain "hsdma" entries.
-- power-domains: Phandle to the power domain that the device is part of
-- #dma-cells: 	The length of the DMA specifier, must be <1>. This one cell
-		in dmas property of a client device represents the channel
-		number.
-Example:
-
-        hsdma: dma-controller@1b007000 {
-		compatible = "mediatek,mt7623-hsdma";
-		reg = <0 0x1b007000 0 0x1000>;
-		interrupts = <GIC_SPI 98 IRQ_TYPE_LEVEL_LOW>;
-		clocks = <&ethsys CLK_ETHSYS_HSDMA>;
-		clock-names = "hsdma";
-		power-domains = <&scpsys MT2701_POWER_DOMAIN_ETH>;
-		#dma-cells = <1>;
-	};
-
-DMA clients must use the format described in dma/dma.txt file.
