1 * Hisilicon 6210 i2s controller
5 - compatible: should be one of the following:
6 - "hisilicon,hi6210-i2s"
7 - reg: physical base address of the i2s controller unit and length of
9 - interrupts: should contain the i2s interrupt.
10 - clocks: a list of phandle + clock-specifier pairs, one for each entry
11 in clock-names.
12 - clock-names: should contain following:
13 - "dacodec"
14 - "i2s-base"
15 - dmas: DMA specifiers for tx dma. See the DMA client binding,
17 - dma-names: should be "tx" and "rx"
18 - hisilicon,sysctrl-syscon: phandle to sysctrl syscon
19 - #sound-dai-cells: Should be set to 1 (for multi-dai)
20 - The dai cell indexes reference the following interfaces:
25 Example for the hi6210 i2s controller:
27 i2s0: i2s@f7118000{
28 compatible = "hisilicon,hi6210-i2s";
29 reg = <0x0 0xf7118000 0x0 0x8000>; /* i2s unit */
30 interrupts = <GIC_SPI 123 IRQ_TYPE_LEVEL_HIGH>; /* 155 "DigACodec_intr"-32 */
33 clock-names = "dacodec", "i2s-base";
35 dma-names = "rx", "tx";
36 hisilicon,sysctrl-syscon = <&sys_ctrl>;
37 #sound-dai-cells = <1>;
40 Then when referencing the i2s controller:
41 sound-dai = <&i2s0 0>; /* index 0 => S2 interface */
