Subject: Add HW_SEEK and TUNER_BAND capabilities to videodev2.h
Author: Hans de Goede hdego...@redhat.com

Bring in the pending (reviewed and acked) changes from:
But not merged. I think this is a bit too quick. It is good practice to wait
with making such changes to v4l-utils until Mauro has merged the videodev2.h
changes as well.
You can always make a clone of v4l-utils and keep your changes there until it
can be merged in the main v4l-utils repository.
I also have a small request:
+static const char *band_names[] = {
+ default,
+ fm-eur_us,
+ fm-japan,
+ fm-russian,
+ fm-weather,
+ am-mw,
+};
Can you rename fm-eur_us to fm-eur-us? That mix of '-' and '_' is very
jarring and awkward to type IMHO.
Regards,
Hans

As these are needed to add support for these new API-s to v4l2-ctl.
