您好！
请问imx8mm sai3上接wm8960 dts怎么配置？我的软件版本是imx-p9.0.0_2.3.0 linux是4.14.98
我目前的配置如下：
wm8960: wm8960@1a {
compatible = "wlf,wm8960";
reg = <0x1a>;
clocks = <&clk IMX8MM_CLK_SAI3_ROOT>;
clock-names = "mclk";
wlf,shared-lrclk;
status = "okay";
};
sound-wm8960 {
compatible = "fsl,imx7d-evk-wm8960",
"fsl,imx-audio-wm8960";
model = "wm8960-audio";
cpu-dai = <&sai3>;
audio-codec = <&wm8960>;
//codec-rpmsg;
codec-master;
/*
* hp-det = <hp-det-pin hp-det-polarity>;
* hp-det-pin: JD1 JD2 or JD3
* hp-det-polarity = 0: hp detect high for headphone
* hp-det-polarity = 1: hp detect high for speaker
*/
//hp-det = <2 0>;
//hp-det-gpios = <&gpio1 13 0>;
//mic-det-gpios = <&gpio1 13 0>;
audio-routing =

};
pinctrl_sai3: sai3grp {

};
&sai3 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_sai3>;
assigned-clocks = <&clk IMX8MM_CLK_SAI3>;
assigned-clock-parents = <&clk IMX8MM_AUDIO_PLL1_OUT>;
assigned-clock-rates = <24576000>; //12288000 24576000 12289600
fsl,sai-asynchronous;
status = "okay";
};
以上配置，
tinyplay 播放wav文件 始终没有输出，并且有提示播放采样率错误
