+NVIDIA Tegra30 HDA controller
+
+Required properties:
+- compatible : "nvidia,tegra30-hda"
+- 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";
+ resets = <&tegra_car 125>, /* hda */
+ <&tegra_car 128>; /* hda2hdmi */
