Hi Mark, Liam

These are redo of below patches

>       ASoC: ak4642: headphone/stereo-line output control
>       ASoC: ak4642: add ak4648 support

Kuninori Morimoto (5):
      ASoC: ak4642: add ak4642_set_bias_level()
      ASoC: ak4642: add DAPM support for HeadPhone Output
      ASoC: ak4642: add headphone mute switch control
      ASoC: ak4642: add Line out support
      ASoC: ak4642: add ak4648 support

This time I tried to use DAPM for "Output".
I will try "Input" case in the future
