ASoC: tegra: add tegra+RT5640 machine driver Initially, this binding and driver only describe/support playback to headphones and speakers. This driver will support Beaver and Dalmore. Signed-off-by: Stephen Warren <swarren@nvidia.com> Signed-off-by: Mark Brown <broonie@linaro.org>

NVIDIA Tegra audio complex, with RT5640 CODEC
Required properties:
- compatible : "nvidia,tegra-audio-rt5640"
- clocks : Must contain an entry for each entry in clock-names.
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.

ASoC: tegra: support a Mic Jack in the Tegra+RT5640 machine driver Add a Mic Jack widget to the Tegra+RT5640 machine driver, and document this in the DT binding. This enables the DT to include the Mic Jack in the audio routing table, and hence enables capture of audio, in addition to the previously-working playback.

- nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
connected to the CODEC.
- nvidia,audio-codec : The phandle of the RT5640 audio codec. This binding
assumes that AIF1 on the CODEC is connected to Tegra.
Optional properties:
- nvidia,hp-det-gpios : The GPIO that detects headphones are plugged in
