The HP Elitepad 1000 G2 has 2 headset jacks:
1. on the dock which uses the output of the codecs built-in HP-amp + the standard IN2 input which is always used with the headset-jack.
2. on the tablet itself, this uses the line-out of the codec, combined with an external HP-amp + IN1 for the headset-mic.
This series adds support for this, resolving: https://bugzilla.kernel.org/show_bug.cgi?id=213415
Note this series does not add jack-detect support. I plan to add that with a follow-up series when I can make some time to implement that.
