It's my fault. Sorry :( I didn't know that clk id is what I need to specify in devicetree. For SMA1303 device, only bclk is possible, not using MCLK. So, if there is an id called mclk, only the log that says that it is not supported is left. Since MCLK is unusable, it seems appropriate to delete the contents. I rewrite that patch. And then, I'll check the clk_get function further and add it if necessary. Thanks! Best regards, Kiseok Jo
