[PATCH v1 0/7] ASoC: dt-bindings: Add/Update #sound-dai-cells to Tegra related codecs

[Svyatoslav Ryhel]

Add/Update #sound-dai-cells to some codecs often used by Tegra devices.
Document #sound-dai-cells property for i2s and ac97 nodes of Tegra20
and Tegra30 devices since they all provide a single dai cell. Add these
properties to SoC level Tegra audio-related nodes. This is required for
creating more complex audio paths.
