This RFC patch series adds the control handling framework and implements
it in ivtv and all subdev drivers used by ivtv.
It is a bare-bones implementation, so no sysfs or debugfs enhancements.
Any comments are welcome.
Once this is in then we can start migrating all subdev drivers to this
framework, followed by all bridge drivers. Converted subdev drivers can
still be used by unconverted bridge drivers. Once all bridge drivers are
converted the subdev backwards compatibility code can be removed.
The same is true for the cx2341x module: both converted and unconverted
bridge drivers are supported. Once all bridge drivers that use this module
are converted the compat code can be removed from cx2341x (and that will
save about 1060 lines of hard to understand code).
Before this can be merged Laurent Pinchart will have to verify that this
new framework can be used with UVC. Note to Laurent: v4l2_ctrl_new_custom()
allows you to pass a 'void *priv' pointer when creating the control. I'm
pretty sure you need this to associate a V4L control with a UVC data struct.
Should you need it, then it will be trivial to add a flag that will cause
the driver to kfree the priv pointer when the control is freed.
Regards,
Hans
