1 TI EDMA
2
3 Required properties:
4 - compatible : "ti,edma3"
5 - #dma-cells: Should be set to <1>
6 Clients should use a single channel number per DMA request.
7 - reg: Memory map for accessing module
8 - interrupt-parent: Interrupt controller the interrupt is routed through
9 - interrupts: Exactly 3 interrupts need to be specified in the order:
10 1. Transfer completion interrupt.
11 2. Memory protection interrupt.
12 3. Error interrupt.
13 Optional properties:
14 - ti,hwmods: Name of the hwmods associated to the EDMA
15 - ti,edma-xbar-event-map: Crossbar event to channel map
16
17 Deprecated properties:
18 Listed here in case one wants to boot an old kernel with new DTB. These
19 properties might need to be added to the new DTS files.
20 - ti,edma-regions: Number of regions
21 - ti,edma-slots: Number of slots
22 - dma-channels: Specify total DMA channels per CC
23
24 Example:
25
26 edma: edma@49000000 {
27 reg = <0x49000000 0x10000>;
28 interrupt-parent = <&intc>;
29 interrupts = <12 13 14>;
30 compatible = "ti,edma3";
31 ti,hwmods = "tpcc", "tptc0", "tptc1", "tptc2";
32 #dma-cells = <1>;
33 ti,edma-xbar-event-map = /bits/ 16 <1 12
34 2 13>;
35 };
