NVIDIA Tegra 20 I2S controller



Required properties:

- compatible : "nvidia,tegra20-i2s"

- reg : Should contain I2S registers location and length

- interrupts : Should contain I2S interrupt

- resets : Must contain an entry for each entry in reset-names.

  See ../reset/reset.txt for details.

- reset-names : Must include the following entries:

  - i2s

- dmas : Must contain an entry for each entry in clock-names.

  See ../dma/dma.txt for details.

- dma-names : Must include the following entries:

  - rx

  - tx

- clocks : Must contain one entry, for the module clock.

  See ../clocks/clock-bindings.txt for details.



Example:



i2s@70002800 {

	compatible = "nvidia,tegra20-i2s";

	reg = <0x70002800 0x200>;

	interrupts = < 45 >;

	clocks = <&tegra_car 11>;

	resets = <&tegra_car 11>;

	reset-names = "i2s";

	dmas = <&apbdma 21>, <&apbdma 21>;

	dma-names = "rx", "tx";

};

title: NVIDIA Tegra20 I2S Controller



description: |

  The I2S Controller streams synchronous serial audio data between system

  memory and an external audio device. The controller supports the I2S Left

  Justified Mode, Right Justified Mode, and DSP mode formats.
