-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";
-};
