  • The WM8960 headphone outputs can be run in capless mode with OUT3
    used to drive a pseudo ground for the headphone drivers. In this
    mode the mono mixer is not used, the mixer should be turned on
    in concert with the headphone output drivers and the device bias
    levels are managed differently.

    Also tweak the existing bias management to remove the use of active
    discharge while we're at it since that's often audible.

  • Avoids machine files having to peer into sound/soc which is a bit
    rude and icky.
