* Broadcom BCM2835 SoC I2S/PCM module
2
-
3
-
Required properties:
4
-
- compatible: "brcm,bcm2835-i2s"
5
-
- reg: Should contain PCM registers location and length.
6
-
- clocks: the (PCM) clock to use
7
-
- dmas: List of DMA controller phandle and DMA request line ordered pairs.
8
-
- dma-names: Identifier string for each DMA request line in the dmas property.
9
-
These strings correspond 1:1 with the ordered pairs in dmas.
10
-
11
-
One of the DMA channels will be responsible for transmission (should be
12
-
named "tx") and one for reception (should be named "rx").
13
-
14
-
Example:
15
-
16
-
bcm2835_i2s: i2s@7e203000 {
17
-
compatible = "brcm,bcm2835-i2s";
18
-
reg = <0x7e203000 0x24>;
19
-
clocks = <&clocks BCM2835_CLOCK_PCM>;
20
-
21
-
dmas = <&dma 2>,
22
-
<&dma 3>;
23
-
dma-names = "tx", "rx";
24
-
