-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.
