NVIDIA Tegra audio complex
|
|
|
|
Required properties:
|
|
- compatible : "nvidia,tegra-audio-wm8753"
|
|
- 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,model : The user-visible name of this sound complex.
|
|
- nvidia,audio-routing : A list of the connections between audio components.
|
|
Each entry is a pair of strings, the first being the connection's sink,
|
|
the second being the connection's source. Valid names for sources and
|
|
sinks are the WM8753's pins, and the jacks on the board:
