DesignWare I2S controller
|
|
|
|
Required properties:
|
|
- compatible : Must be "snps,designware-i2s"
|
|
- reg : Must contain the I2S core's registers location and length
|
|
- clocks : Pairs of phandle and specifier referencing the controller's
|
|
clocks. The controller expects one clock: the clock used as the sampling
|
|
rate reference clock sample.
|
|
- clock-names : "i2sclk" for the sample rate reference clock.
|
|
- dmas: Pairs of phandle and specifier for the DMA channels that are used by
|
|
the core. The core expects one or two dma channels: one for transmit and
|
|
one for receive.
|
|
- dma-names : "tx" for the transmit channel, "rx" for the receive channel.
|
|
|
|
Optional properties:
|
|
- interrupts: The interrupt line number for the I2S controller. Add this
|
|
parameter if the I2S controller that you are using does not support DMA.
|
|
|

|
reg = <0x0 0x7ff90000 0x0 0x1000>;
|
|
clocks = <&scpi_i2sclk 0>;
|
|
clock-names = "i2sclk";
|
|
#sound-dai-cells = <0>;
|
|
dmas = <&dma0 5>;
|

dma-names = "tx";
