Applied Micro X-Gene SoC DMA nodes
DMA nodes are defined to describe on-chip DMA interfaces in
APM X-Gene SoC.
Required properties for DMA interfaces:
- compatible: Should be "apm,xgene-dma".
- device_type: set to "dma".
- reg: Address and length of the register set for the device.
It contains the information of registers in the following order:
1st - DMA control and status register address space.
2nd - Descriptor ring control and status register address space.
3rd - Descriptor ring command register address space.
4th - Soc efuse register address space.
- interrupts: DMA has 5 interrupts sources. 1st interrupt is
DMA error reporting interrupt. 2nd, 3rd, 4th and 5th interrupts
are completion interrupts for each DMA channels.
- clocks: Reference to the clock entry.
Optional properties:
- dma-coherent : Present if dma operations are coherent
Example:
dmaclk: dmaclk@1f27c000 {
compatible = "apm,xgene-device-clock";
#clock-cells = <1>;
clocks = <&socplldiv2 0>;
reg = <0x0 0x1f27c000 0x0 0x1000>;
reg-names = "csr-reg";
clock-output-names = "dmaclk";
};
dma: dma@1f270000 {
compatible = "apm,xgene-storm-dma";
device_type = "dma";
reg = <0x0 0x1f270000 0x0 0x10000>,
<0x0 0x1f200000 0x0 0x10000>,
<0x0 0x1b008000 0x0 0x2000>,
<0x0 0x1054a000 0x0 0x100>;
interrupts = <0x0 0x82 0x4>,

<0x0 0xb9 0x4>,
<0x0 0xba 0x4>,
<0x0 0xbb 0x4>;

* Ingenic JZ4780 DMA Controller
Required properties:
- compatible: Should be "ingenic,jz4780-dma"
- reg: Should contain the DMA controller registers location and length.
- interrupts: Should contain the interrupt specifier of the DMA controller.
- interrupt-parent: Should be the phandle of the interrupt controller that
- clocks: Should contain a clock specifier for the JZ4780 PDMA clock.
- #dma-cells: Must be <2>. Number of integer cells in the dmas property of
DMA clients (see below).
Optional properties:
- ingenic,reserved-channels: Bitmask of channels to reserve for devices that
need a specific channel. These channels will only be assigned when explicitly
requested by a client. The primary use for this is channels 0 and 1, which
can be configured to have special behaviour for NAND/BCH when using
programmable firmware.
Example:
dma: dma@13420000 {
compatible = "ingenic,jz4780-dma";
reg = <0x13420000 0x10000>;
interrupt-parent = <&intc>;
interrupts = <10>;
clocks = <&cgu JZ4780_CLK_PDMA>;
#dma-cells = <2>;
ingenic,reserved-channels = <0x3>;
};
DMA clients must use the format described in dma.txt, giving a phandle to the
DMA controller plus the following 2 integer cells:
1. Request type: The DMA request type for transfers to/from the device on
the allocated channel, as defined in the SoC documentation.
2. Channel: If set to 0xffffffff, any available channel will be allocated for
the client. Otherwise, the exact channel specified will be used. The channel
should be reserved on the DMA controller using the ingenic,reserved-channels
property.
Example:
uart0: serial@10030000 {
...
dmas = <&dma 0x14 0xffffffff
&dma 0x15 0xffffffff>;
dma-names = "tx", "rx";
...
};

* Renesas USB DMA Controller Device Tree bindings
Required Properties:
- compatible: must contain "renesas,usb-dmac"
- reg: base address and length of the registers block for the DMAC
- interrupts: interrupt specifiers for the DMAC, one for each entry in
interrupt-names.

channel number ranging from zero to the number of channels minus one.
- clocks: a list of phandle + clock-specifier pairs.

port connected to the DMA client.
