An optional property "nvidia,model" is introduced for hda to pass custom
name for the sound card. The suffix "-hda" in the name passed is useful
to distinguish between multiple cards available for a platform.
When the property is not specified, default name("tegra-hda") mentioned
in hda driver is used. This property can be added in platform specific
file of the board and card name can relate to the board in use.

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";
|
|
};
