ASoC: dt-bindings: tegra30-i2s: convert to dt schema 



Convert NVIDIA Tegra30 I2S binding to DT schema and
add "clock-names" property used by multiple tegra i2s blocks
in arch/arm64/boot/dts/nvidia/tegra132.dtsi. This is not a
required property by the binding.

NVIDIA Tegra30 I2S controller



Required properties:

- compatible : For Tegra30, must contain "nvidia,tegra30-i2s".  For Tegra124,

  must contain "nvidia,tegra124-i2s".  Otherwise, must contain

  "nvidia,<chip>-i2s" plus at least one of the above, where <chip> is

  tegra114 or tegra132.

- reg : Should contain I2S registers location and length

- clocks : Must contain one entry, for the module clock.

  See ../clocks/clock-bindings.txt for details.

- 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,ahub-cif-ids : The list of AHUB CIF IDs for this port, rx (playback)

  first, tx (capture) second. See nvidia,tegra30-ahub.txt for values.



Example:



i2s@70080300 {

	compatible = "nvidia,tegra30-i2s";

	reg = <0x70080300 0x100>;

	nvidia,ahub-cif-ids = <4 4>;

	clocks = <&tegra_car 11>;

	resets = <&tegra_car 11>;

	reset-names = "i2s";

};
