[alsa-devel] [PATCH v2 0/3] Add support simple-card parse jack detection via external codec

[Xing Zheng]

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.
