Hi Xiubo,
My DT is
sound {
compatible = "simple-audio-card";
simple-audio-card,name = "Cubox Audio";
simple-audio-card,dai-link@0 { /* I2S - HDMI */
format = "i2s";
cpu {
sound-dai = <&audio1 0>;
};
codec {
sound-dai = <&hdmi 0>;
};
};
...
I was getting 0x1001 as the format (codec clk & FRM master and i2s').
With your patch, I get 0x4000 (clk master & frame slave and no format).
