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.
