如何解决 DTS 中缺少的时钟部分  

sound_out:sound-out{
兼容="wnz、pm-out";
TI、模型="音频输出";
TI、audio-codec =<&tas5508c>;
TI、McASP 控制器=<&McASP0>;
TI、编解码器时钟速率=<24576000>;

时钟名称="??"

时钟="???"

};


第417章: 
MCLK = devm_clk_get (&pdev->dev、"MCLK");
if (ptr_ERR (MCLK)==-EPROBE_DEFER){
  return -EPROBE_DEFER;
{else if (IS_ERR(MCLK)){
  dev_dbg (&pdev->dev、"MCLK not found.\n");
  MCLK = NULL;
}

正在获取

[ 14.57057575] DaVinci_EVM 音频输入:未找到 MCLK。

怎样的  
DTS 如下

sound_out:sound-out{
兼容="wnz、pm-out";
TI、模型="音频输出";
TI、audio-codec =<&tas5508c>;
TI、McASP 控制器=<&McASP0>;
TI、编解码器时钟速率=<24576000>;

时钟名称="FCK"

Clocks =(&l4ls_gclk>

};

和 Davinci-EVM 部分

MCLK = devm_clk_get (&pdev->dev、"fck");
if (ptr_ERR (MCLK)==-EPROBE_DEFER){
  return -EPROBE_DEFER;
{else if (IS_ERR(MCLK)){
  dev_dbg (&pdev->dev、"MCLK not found.\n");
  MCLK = NULL;
}
