1 | Imagination Technologies I2S Input Controller |
2 | ||
3 | Required Properties: | |
4 | ||
5 | - compatible : Compatible list, must contain "img,i2s-in" | |
6 | ||
7 | - #sound-dai-cells : Must be equal to 0 | |
8 | ||
9 | - reg : Offset and length of the register set for the device | |
10 | ||
11 | - clocks : Contains an entry for each entry in clock-names | |
12 | ||
13 | - clock-names : Must include the following entry: | |
14 | "sys" The system clock | |
15 | ||
16 | - dmas: Contains an entry for each entry in dma-names. | |
17 | ||
18 | - dma-names: Must include the following entry: | |
19 | "rx" Single DMA channel used by all active I2S channels | |
20 | ||
21 | - img,i2s-channels : Number of I2S channels instantiated in the I2S in block | |
22 | ||
23 | Optional Properties: | |
24 | ||
25 | - interrupts : Contains the I2S in interrupts. Depending on | |
26 | the configuration, there may be no interrupts, one interrupt, | |
27 | or an interrupt per I2S channel. For the case where there is | |
28 | one interrupt per channel, the interrupts should be listed | |
29 | in ascending channel order | |
30 | ||
31 | - resets: Contains a phandle to the I2S in reset signal | |
32 | ||
33 | - reset-names: Contains the reset signal name "rst" | |
34 | ||
35 | Example: | |
36 | ||
37 | i2s_in: i2s-in@18100800 { | |
38 | compatible = "img,i2s-in"; | |
39 | reg = <0x18100800 0x200>; | |
40 | interrupts = <GIC_SHARED 7 IRQ_TYPE_LEVEL_HIGH>; | |
41 | dmas = <&mdc 30 0xffffffff 0>; | |
42 | dma-names = "rx"; | |
43 | clocks = <&cr_periph SYS_CLK_I2S_IN>; | |
44 | clock-names = "sys"; | |
45 | img,i2s-channels = <6>; | |
46 | #sound-dai-cells = <0>; | |
47 | }; |
