ADI AXI-I2S controller
Required properties:
- compatible : Must be "adi,axi-i2s-1.00.a"
- reg : Must contain I2S core's registers location and length
- clocks : Pairs of phandle and specifier referencing the controller's clocks.
The controller expects two clocks, the clock used for the AXI interface and
the clock used as the sampling rate reference clock sample.
- clock-names : "axi" for the clock to the AXI interface, "ref" 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 two dma channels, one for transmit and one for
receive.
- dma-names : "tx" for the transmit channel, "rx" for the receive channel.
For more details on the 'dma', 'dma-names', 'clock' and 'clock-names' properties
please check:
* resource-names.txt
* clock/clock-bindings.txt
* dma/dma.txt
Example:
i2s: i2s@0x77600000 {
compatible = "adi,axi-i2s-1.00.a";
reg = <0x77600000 0x1000>;
clocks = <&clk 15>, <&audio_clock>;
clock-names = "axi", "ref";
dmas = <&ps7_dma 0>, <&ps7_dma 1>;
dma-names = "tx", "rx";
};
