+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, hdacodec_2x, hda2hdmi
+- 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, hdacodec_2x, hda2hdmi
+
+Example:
+
+hda@0,70030000 {
+       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";
