[PATCH v3 15/24] media: Add userspace header file for i.MX

Steve Longerbeam slongerbeam at gmail.com
Fri Jan 6 18:11:33 PST 2017


This adds a header file for use by userspace programs wanting to interact
with the i.MX media driver. It defines custom v4l2 controls and events
generated by the i.MX v4l2 subdevices.
