1MediaTek High-Speed DMA Controller 2================================== 3 4This device follows the generic DMA bindings defined in dma/dma.txt. 5 6Required properties: 7 8- compatible: Must be one of 9 "mediatek,mt7622-hsdma": for MT7622 SoC 10 "mediatek,mt7623-hsdma": for MT7623 SoC 11- reg: Should contain the register's base address and length. 12- interrupts: Should contain a reference to the interrupt used by this 13 device. 14- clocks: Should be the clock specifiers corresponding to the entry in 15 clock-names property. 16- clock-names: Should contain "hsdma" entries. 17- power-domains: Phandle to the power domain that the device is part of 18- #dma-cells: The length of the DMA specifier, must be <1>. This one cell 19 in dmas property of a client device represents the channel 20 number. 21Example: 22 23 hsdma: dma-controller@1b007000 { 24 compatible = "mediatek,mt7623-hsdma"; 25 reg = <0 0x1b007000 0 0x1000>; 26 interrupts = <GIC_SPI 98 IRQ_TYPE_LEVEL_LOW>; 27 clocks = <ðsys CLK_ETHSYS_HSDMA>; 28 clock-names = "hsdma"; 29 power-domains = <&scpsys MT2701_POWER_DOMAIN_ETH>; 30 #dma-cells = <1>; 31 }; 32 33DMA clients must use the format described in dma/dma.txt file.
