-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 at 70030000 {
-	compatible = "nvidia,tegra124-hda", "nvidia,tegra30-hda";
-	reg = <0x0 0x70030000 0x0 0x10000>;
-	interrupts = <GIC_SPI 81 IRQ_TYPE_LEVEL_HIGH>;
-	clocks = <&tegra_car TEGRA124_CLK_HDA>,
-		 <&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 */
-		 <&tegra_car 111>; /* hda2codec_2x */
-	reset-names = "hda", "hda2hdmi", "hda2codec_2x";
