Hi, In most cases, many codecs already supports jack detection, previouslly, we need to create a customized machine driver every time.
In my opinion, the codec fill the detect_jack explicitly and tell sound framework it supports the jack detection, the simple-card is able to parse the dts file and call the export function to initialize the jace detection via the codec.
I think that it will bring better flexibility.
Thanks.
