NVIDIA Tegra audio complex for TrimSlice
|
|
|
|
Required properties:
|
|
- compatible : "nvidia,tegra-audio-trimslice"
|
|
- clocks : Must contain an entry for each entry in clock-names.
|
|
- clock-names : Must include the following entries:
|
|
"pll_a" (The Tegra clock of that name),
|
|
"pll_a_out0" (The Tegra clock of that name),
|
|
"mclk" (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
|
|
- nvidia,i2s-controller : The phandle of the Tegra I2S1 controller
|
|
- nvidia,audio-codec : The phandle of the WM8903 audio codec
|
|
|
|
Example:
|
|
|
|
sound {
|
|
compatible = "nvidia,tegra-audio-trimslice";
|
|
nvidia,i2s-controller = <&tegra_i2s1>;
|
|
nvidia,audio-codec = <&codec>;
|
|
clocks = <&tegra_car 112>, <&tegra_car 113>, <&tegra_car 93>;
|
|
clock-names = "pll_a", "pll_a_out0", "mclk";
|
|
};
