From: Hans Verkuil <[email protected]>
This patch series modifies v4l2-event, videobuf and various
drivers that do not use vb2 or videobuf at all to store the
event and buffer timestamps internally as a u64 (ktime_get_ns()).
Only when interfacing with the userspace API are these timestamps
converted to a timespec or timeval.
The final patch drops the now unused v4l2_get_timestamp().
This simplifies the work needed to support Y2038-compatible
timeval/timespec structures. It also ensures consistent
behavior for all media drivers.
Regards,
Hans
Hans Verkuil (8):
v4l2-event: keep track of the timestamp in ns
videobuf: use u64 for the timestamp internally
meye: use u64 for the timestamp internally
cpia2: use u64 for the timestamp internally
stkwebcam: use u64 for the timestamp internally
usbvision: use u64 for the timestamp internally
zoran: use u64 for the timestamp internally
v4l2-common: drop v4l2_get_timestamp
