What would userspace do instead ?
Is there a use case for formats not being known at pipeline start time ?
Is the userspace expected to enable all links with the VALIDATE_LATE
flags ?
for_each_video_node() {
set_format()
clear_validate_late();
vidioc_streamon()
}
As I understand it, the use case is solely delay setting the format on
the video device and its sink pads ?

Can you elaborate a little on why a per-ioctl flag is required ?
Doesn't this open the door to possible mixups ?
I fail to see what the advantage is over per-subdev_fh client
capabilities.

Do we expect drivers that still use in-kernel operation calls to be
ported to use streams ?
I'll review the rest of the series in the meantime.
