1Imagination Technologies I2S Output Controller
2
3Required Properties:
4
5  - compatible : Compatible list, must contain "img,i2s-out"
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 entries:
14	"sys"	The system clock
15	"ref"	The reference clock
16
17  - dmas: Contains an entry for each entry in dma-names.
18
19  - dma-names: Must include the following entry:
20	"tx"	Single DMA channel used by all active I2S channels
21
22  - img,i2s-channels : Number of I2S channels instantiated in the I2S out block
23
24  - resets: Contains a phandle to the I2S out reset signal
25
26  - reset-names: Contains the reset signal name "rst"
27
28Optional Properties:
29
30  - interrupts : Contains the I2S out interrupts. Depending on
31	the configuration, there may be no interrupts, one interrupt,
32	or an interrupt per I2S channel. For the case where there is
33	one interrupt per channel, the interrupts should be listed
34	in ascending channel order
35
36Example:
37
38i2s_out: i2s-out@18100A00 {
39	compatible = "img,i2s-out";
40	reg = <0x18100A00 0x200>;
41	interrupts = <GIC_SHARED 13 IRQ_TYPE_LEVEL_HIGH>;
42	dmas = <&mdc 23 0xffffffff 0>;
43	dma-names = "tx";
44	clocks = <&cr_periph SYS_CLK_I2S_OUT>,
45		 <&clk_core CLK_I2S>;
46	clock-names = "sys", "ref";
47	img,i2s-channels = <6>;
48	resets = <&pistachio_reset PISTACHIO_RESET_I2S_OUT>;
49	reset-names = "rst";
50	#sound-dai-cells = <0>;
51};
