* [media] media: videobuf2: Move timestamp to vb2_bufferJunghak Sung2015-12-181-1/+1
| | | | | | | | | | | | | | Move timestamp from struct vb2_v4l2_buffer to struct vb2_buffer for common use, and change its type to u64 in order to handling y2038 problem. This patch also includes all device drivers' changes related to this restructuring.

* [media] vb2: drop v4l2_format argument from queue_setupHans Verkuil2015-12-181-8/+9
| | | | | | | | | | | | | | | | | | | | | The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
