1NVIDIA Tegra30 HDA controller
2
3Required properties:
4- compatible : For Tegra30, must contain "nvidia,tegra30-hda".  Otherwise,
5  must contain '"nvidia,<chip>-hda", "nvidia,tegra30-hda"', where <chip> is
6  tegra114, tegra124, or tegra132.
7- reg : Should contain the HDA registers location and length.
8- interrupts : The interrupt from the HDA controller.
9- clocks : Must contain an entry for each required entry in clock-names.
10  See ../clocks/clock-bindings.txt for details.
11- clock-names : Must include the following entries: hda, hda2hdmi, hda2codec_2x
12- resets : Must contain an entry for each entry in reset-names.
13  See ../reset/reset.txt for details.
14- reset-names : Must include the following entries: hda, hda2hdmi, hda2codec_2x
15
16Optional properties:
17- nvidia,model : The user-visible name of this sound complex. Since the property
18  is optional, legacy boards can use default name provided in hda driver.
