-NVIDIA Tegra30 HDA controller
-
-Required properties:
-- compatible : For Tegra30, must contain "nvidia,tegra30-hda". Otherwise,
- must contain '"nvidia,<chip>-hda", "nvidia,tegra30-hda"', where <chip> is
- tegra114, tegra124, or tegra132.
-- reg : Should contain the HDA registers location and length.
-- interrupts : The interrupt from the HDA controller.
-- clocks : Must contain an entry for each required entry in clock-names.
- See ../clocks/clock-bindings.txt for details.
-- clock-names : Must include the following entries: hda, hda2hdmi, hda2codec_2x
-- resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
-- reset-names : Must include the following entries: hda, hda2hdmi, hda2codec_2x
-
-Optional properties:
-- nvidia,model : The user-visible name of this sound complex. Since the property
- is optional, legacy boards can use default name provided in hda driver.
-
-Example:
-
-hda@...30000 {
- compatible = "nvidia,tegra124-hda", "nvidia,tegra30-hda";
- reg = <0x0 0x70030000 0x0 0x10000>;

- <&tegra_car TEGRA124_CLK_HDA2HDMI>,
- <&tegra_car TEGRA124_CLK_HDA2CODEC_2X>;
- clock-names = "hda", "hda2hdmi", "hda2codec_2x";
- resets = <&tegra_car 125>, /* hda */
- <&tegra_car 128>, /* hda2hdmi */

- reset-names = "hda", "hda2hdmi", "hda2codec_2x";
