1*4882a593SmuzhiyunNVIDIA Tegra audio complex, with MAX98090 CODEC
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunRequired properties:
4*4882a593Smuzhiyun- compatible : "nvidia,tegra-audio-max98090"
5*4882a593Smuzhiyun- clocks : Must contain an entry for each entry in clock-names.
6*4882a593Smuzhiyun  See ../clocks/clock-bindings.txt for details.
7*4882a593Smuzhiyun- clock-names : Must include the following entries:
8*4882a593Smuzhiyun  - pll_a
9*4882a593Smuzhiyun  - pll_a_out0
10*4882a593Smuzhiyun  - mclk (The Tegra cdev1/extern1 clock, which feeds the CODEC's mclk)
11*4882a593Smuzhiyun- nvidia,model : The user-visible name of this sound complex.
12*4882a593Smuzhiyun- nvidia,audio-routing : A list of the connections between audio components.
13*4882a593Smuzhiyun  Each entry is a pair of strings, the first being the connection's sink,
14*4882a593Smuzhiyun  the second being the connection's source. Valid names for sources and
15*4882a593Smuzhiyun  sinks are the MAX98090's pins (as documented in its binding), and the jacks
16*4882a593Smuzhiyun  on the board:
17*4882a593Smuzhiyun
18*4882a593Smuzhiyun  * Headphones
19*4882a593Smuzhiyun  * Speakers
20*4882a593Smuzhiyun  * Mic Jack
21*4882a593Smuzhiyun  * Int Mic
22*4882a593Smuzhiyun
23*4882a593Smuzhiyun- nvidia,i2s-controller : The phandle of the Tegra I2S controller that's
24*4882a593Smuzhiyun  connected to the CODEC.
25*4882a593Smuzhiyun- nvidia,audio-codec : The phandle of the MAX98090 audio codec.
26*4882a593Smuzhiyun
27*4882a593SmuzhiyunOptional properties:
28*4882a593Smuzhiyun- nvidia,hp-det-gpios : The GPIO that detect headphones are plugged in
29*4882a593Smuzhiyun- nvidia,mic-det-gpios : The GPIO that detect microphones are plugged in
