V4L framework progress

This page contains the status of all drivers with respect to their adoption of all the new structures that the V4L framework offers.
This should help in identifying those drivers that need more work.
It is expected that this page will be continuously updated whenever new conversion tasks appear.
Note: the driver lists are not yet complete. This is work in progress.
Bridge Drivers
- driver
The driver name
- interface
Type of bridge interface
- V4L API
Whether the driver implements the V4L2 API or still uses the old V4L1 API
- v4l2_device
Whether the driver uses struct v4l2_device
- video_ioctls
Whether the driver uses the video_ioctl2 fops .ioctl op
- have hardware
Who can test this driver?
AW = Andy Walls
DH = Devin Heitmueller
HdG = Hans de Goede
HV = Hans Verkuil
LP = Laurent Pinchart
MI = Mike Isely
- BKL
Still uses the Big Kernel Lock
