----------------------------
-What: Support for driver specific ioctls in the pwc driver (everything
- defined in media/pwc-ioctl.h)
-When: 3.3
-Why: This stems from the v4l1 era, with v4l2 everything can be done with
- standardized v4l2 API calls
-Who: Hans de Goede <hdegoede@redhat.com>
-
-----------------------------
-
What: Software emulation of arbritary resolutions in the pwc driver
When: 3.3
Why: The pwc driver claims to support any resolution between 160x120
