+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 = <ðsys 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.
