<reduce audience to linux-imx> Shengjiu,
Can you help me with this? Specifically: I couldn't find the schematic showing the exact connection pins between SAI and wm8524 codec. I looked into our internal tree and the wm8524 codec always handles CLK_SAIX_ROOT but Fabio has a good point. This clock doesn't feeds the codec. Unless, we can really look into the schematics and prove it otherwise.
