I2S MCLK on Core-3399-JD4

alex.mamonov

Hi!

I'm trying to use I2S1 on Firefly Core-3399-JD4 with TLV320AIC3100 codec. This is how I describe it in the dts:

1. / {
   
2.   tlv320aic31xx-sound {
   
3.     compatible = "simple-audio-card";
   
4.     status = "okay";
   
5.     simple-audio-card,format = "i2s";
   
6.     simple-audio-card,name = "rockchip,tlv320aic31xx-codec";
   
7.     simple-audio-card,widgets =
   
8.                             "Microphone", "Mic Jack",
   
9.     "Headphone", "Headphone Jack";
   
10.     simple-audio-card,routing =
    
11.     "Mic Jack", "MICBIAS1",
    
12.     "IN1P", "Mic Jack",
    
13.     "Headphone Jack", "HPOL",
    
14.     "Headphone Jack", "HPOR";
    
15.   
    
16.     simple-audio-card,cpu {
    
17.       sound-dai = <&i2s1>;
    
18.       format = "i2s";
    
19.     };
    
20.     simple-audio-card,codec {
    
21.       sound-dai = <&tlv320aic3100>;
    
22.       format = "i2s";
    
23.     };
    
24.   };
    
25. };
    
26. &i2c1 {
    
27.   tlv320aic3100: tlv320aic3100@18 {
    
28.     #sound-dai-cells = <0>;
    
29.     compatible = "ti,tlv320aic3100";
    
30.     reg = <0x18>;
    
31.     status = "okay";
    
32. 
    
33.     HPVDD-supply = <&vcc3v3_sys>;
    
34.     SPRVDD-supply = <&vcc5v0_host>;
    
35.     SPLVDD-supply = <&vcc5v0_host>;
    
36.     AVDD-supply = <&vcc3v3_sys>;
    
37.     IOVDD-supply = <&vcca1v8_codec>;
    
38.     DVDD-supply = <&vcca1v8_codec>;
    
39.   };
    
40. };
    

Copy the code

The drivers starts without errors and I can see audio device in aplay -l output, but there is no sound and I can't see the clocks on MCLK pin. How can I get MCLK on?
