[PATCH v4 0/3] v4l2-dev/ioctl: Add V4L2_CAP_IO_MC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

This series aims to reduce the amount of boiler plate code in video
device drivers who's inputs and/or outputs are controlled by the Media
Controller instead of the V4L2 API.

Patch 1/3 adds a new video device capability flag V4L2_CAP_IO_MC which
if set provides helper implementations for the enum inputs and outputs
ioctrls freeing the video device driver from the need to implement them.

Patch 2/3 and 3/3 converts the R-Car VIN and Intel IPU3 drivers to use 
the new default handlers and capability flag and delete the now  
redundant boiler plate code. I'm sure more video device drivers
can make use of this new flag but as I can only test on these two
platforms I have limited my changes to those.
