From: Hans Verkuil <hverkuil-cisco@xs4all.nl> 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 drivers/media/common/saa7146/saa7146_fops.c | 2 +- drivers/media/pci/bt8xx/bttv-driver.c | 8 +++----- drivers/media/pci/cx18/cx18-mailbox.c | 2 +- drivers/media/pci/meye/meye.c | 8 ++++---- drivers/media/pci/meye/meye.h | 2 +- drivers/media/platform/davinci/vpfe_capture.c | 2 +- drivers/media/platform/fsl-viu.c | 2 +- drivers/media/platform/omap/omap_vout.c | 12 ++++++------ drivers/media/usb/cpia2/cpia2.h | 2 +- drivers/media/usb/cpia2/cpia2_usb.c | 2 +- drivers/media/usb/cpia2/cpia2_v4l.c | 11 +++-------- drivers/media/usb/cx231xx/cx231xx-417.c | 4 ++-- drivers/media/usb/cx231xx/cx231xx-vbi.c | 2 +- drivers/media/usb/cx231xx/cx231xx-video.c | 2 +- drivers/media/usb/stkwebcam/stk-webcam.c | 2 +- drivers/media/usb/tm6000/tm6000-video.c | 2 +- drivers/media/usb/usbvision/usbvision-core.c | 2 +- drivers/media/usb/usbvision/usbvision-video.c | 4 ++-- drivers/media/usb/usbvision/usbvision.h | 2 +- drivers/media/usb/zr364xx/zr364xx.c | 4 ++-- drivers/media/v4l2-core/v4l2-common.c | 10 ---------- drivers/media/v4l2-core/v4l2-event.c | 19 +++++++++---------- drivers/media/v4l2-core/videobuf-core.c | 4 ++-- drivers/staging/media/zoran/zoran.h | 2 +- drivers/staging/media/zoran/zoran_device.c | 4 ++-- drivers/staging/media/zoran/zoran_driver.c | 4 ++-- include/media/v4l2-common.h | 9 --------- include/media/v4l2-event.h | 2 ++ include/media/videobuf-core.h | 2 +- 29 files changed, 54 insertions(+), 79 deletions(-)
