ASoC: Tegra I2S: Add device tree binding Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

NVIDIA Tegra 20 I2S controller
Required properties:
- compatible : "nvidia,tegra20-i2s"
- reg : Should contain I2S registers location and length
- interrupts : Should contain I2S interrupt
ARM: tegra: add missing clock documentation to DT bindings Many of the Tegra DT binding documents say nothing about the clocks or clock-names properties, yet those are present and required in DT files. This patch simply updates the documentation file to match the implicit definition of the binding, based on real-world DT content. All Tegra bindings that mention clocks are updated to have consistent wording and formatting of the clock-related properties.

- clocks : Must contain one entry, for the module clock.
See ../clocks/clock-bindings.txt for details.
ARM: tegra: document reset properties in DT bindings Update all the Tegra DT bindings to require resets/reset-names properties where the HW module has reset inputs. Remove any entries from clocks or clock-names that were only required to identify reset inputs, rather than referring to real clocks. This is a DT-ABI-incompatible change. It is the first of two changes required for me to consider the Tegra DT bindings as stable, the other being conversion to the common DMA DT bindings.

- 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

- nvidia,dma-request-selector : The Tegra DMA controller's phandle and
request selector for this I2S controller
Example:
i2s@70002800 {
compatible = "nvidia,tegra20-i2s";
reg = <0x70002800 0x200>;
interrupts = < 45 >;
nvidia,dma-request-selector = < &apbdma 2 >;
