10926cf696 ALSA: usb-audio: Add quirks for Dell WD19 dock
[ Upstream commit 4413665dd6c528b31284119e3571c25f371e1c36 ]

The WD19 family of docks has the same audio chipset as the WD15. This
change enables jack detection on the WD19.

We don't need the dell_dock_mixer_init quirk for the WD19. It is only
needed because of the dell_alc4020_map quirk for the WD15 in
mixer_maps.c, which disables the volume controls. Even for the WD15,
this quirk was apparently only needed when the dock firmware was not
updated.

c338693262 ALSA: usb-audio: Support jack detection on Dell dock
[ Upstream commit 4b8ea38fabab45ad911a32a336416062553dfe9c ]

The Dell WD15 dock has a headset and a line out port. Add support for
detecting if a jack is inserted into one of these ports.
For the headset jack, additionally determine if a mic is present.

The WD15 contains an ALC4020 USB audio controller and ALC3263 audio codec
from Realtek. It is a UAC 1 device, and UAC 1 does not support jack
detection. Instead, jack detection works by sending HD Audio commands over
vendor-type USB messages.

I found out how it works by looking at USB captures on Windows.
The audio codec is very similar to the one supported by
sound/soc/codecs/rt298.c / rt298.h, some constant names and the mic
detection are adapted from there. The realtek_add_jack function is adapted
from build_connector_control in sound/usb/mixer.c.

I tested this on a WD15 dock with the latest firmware.
