  • 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.
