For U-Boot we allow a GPIO to be specified to enable the codec. Add this to the relevant binding files. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

NVIDIA Tegra audio complex, with MAX98090 CODEC
|
|
|
|
Required properties:
|
|
- compatible : "nvidia,tegra-audio-max98090"
|
|
- clocks : Must contain an entry for each entry in clock-names.
|
|
See ../clocks/clock-bindings.txt for details.
|
|
- clock-names : Must include the following entries:
|
|
- pll_a
|
|
- pll_a_out0
|
|
- 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 MAX98090's pins (as documented in its binding), and the jacks
|
|
on the board:
|
|
|
|
* Headphones
|
|
* Speakers
|
|
* Mic Jack
|
|
* Int Mic
|
|
|
|
- nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
|
|
connected to the CODEC.
|
|
- nvidia,audio-codec : The phandle of the MAX98090 audio codec.
|
|
|
|
Optional properties:
|
|
- nvidia,hp-det-gpios : The GPIO that detect headphones are plugged in
|
|
- nvidia,mic-det-gpios : The GPIO that detect microphones are plugged in
|
|
- codec-enable-gpio : The GPIO used to enable the audio codec
|
|
|
|
Example:
|
|
|
|
sound {
|
|
compatible = "nvidia,tegra-audio-max98090-venice2",
|
|
"nvidia,tegra-audio-max98090";
