+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@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";
+	nvidia,model = "jetson-tk1-hda";
+};
