ASoC: da7219: Add jack insertion detection polarity
Merge series from David Rau <David.Rau.opensource@dm.renesas.com>:
This patchset adds the support of DA7219 Jack insertion detection
polarity selection.
The first patch replaces the old txt binding with a new schema binding.
The second patch adds `dlg,jack-ins-det-pty` property for Jack
insertion detection polarity selection.
The last patch adds the driver support for this topic.
The series has been verified on the DA7219 development kit.
