1 MediaTek High-Speed DMA Controller
2 ==================================
4 This device follows the generic DMA bindings defined in dma/dma.txt.
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
14 - clocks: Should be the clock specifiers corresponding to the entry in
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
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>;
33 DMA clients must use the format described in dma/dma.txt file.
