* Milbeaut AHB DMA Controller
|
|
|
|
Milbeaut AHB DMA controller has transfer capability below.
|
|
- device to memory transfer
|
|
- memory to device transfer
|
|
|
|
Required property:
|
|
- compatible: Should be "socionext,milbeaut-m10v-hdmac"
|
|
- reg: Should contain DMA registers location and length.
|
|
- interrupts: Should contain all of the per-channel DMA interrupts.
|
|
Number of channels is configurable - 2, 4 or 8, so
|
|
the number of interrupts specified should be {2,4,8}.
|
|
- #dma-cells: Should be 1. Specify the ID of the slave.
|
|
- clocks: Phandle to the clock used by the HDMAC module.
|
|
|
|
|
|
Example:
|
|
|
|
hdmac1: dma-controller@1e110000 {
|
|
compatible = "socionext,milbeaut-m10v-hdmac";
|
|
reg = <0x1e110000 0x10000>;
|
|
interrupts = <0 132 4>,
|
|
<0 133 4>,
|
|
<0 134 4>,
|
|
<0 135 4>,
|
|
<0 136 4>,
|
|
<0 137 4>,
|
|
<0 138 4>,
|
|
<0 139 4>;
|
|
#dma-cells = <1>;
|
|
clocks = <&dummy_clk>;
|
|
};
