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


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.

Changes in v1:
- clean up the commit message and notes

Xing Zheng (3):
  ASoC: jack: Add an export of a function that calls the codec jack
    detection
  ASoC: simple-card: Add support call the codec jack detection after
    parse dts
  ASoC: da7219: Add detect_jack callback in the snd_soc_codec_driver
