[media] v4l: move v4l2 core into a separate directory

2012-08-14T02:02:38+00:00

Currently, the v4l2 core is mixed together with other non-core drivers. Move them into a separate directory. Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-dev: remove V4L2_FL_LOCK_ALL_FOPS

2012-08-09T23:18:16+00:00

All drivers that needed V4L2_FL_LOCK_ALL_FOPS have been converted, so remove this flag altogether. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-dev.c: Move video_put() after debug printk

2012-07-31T00:11:35+00:00

It is possible that video_put() releases video_device struct, provoking a panic when debug printk wants to get video_device node name. Signed-off-by: Ezequiel Garcia Acked-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: add core support for the new VIDIOC_ENUM_FREQ_BANDS ioctl

2012-07-30T23:23:05+00:00

This adds the usual core support code for this new ioctl. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-dev: G_PARM was incorrectly enabled for all video nodes

2012-07-30T22:20:44+00:00

G_PARM should only be enabled if: - vidioc_g_parm is present - or: it is a video node and vidioc_g_std or tvnorms are set. Without this additional check v4l2-compliance would complain about being able to use g_parm when it didn't expect it. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-dev: forgot to add VIDIOC_DV_TIMINGS_CAP

2012-07-30T22:11:04+00:00

The VIDIOC_DV_TIMINGS_CAP ioctl check wasn't added to determine_valid_ioctls(). This caused this ioctl to always return -ENOTTY. Signed-off-by: Hans Verkuil Cc: stable@kernel.org Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-dev.c: also add debug support for the fops

[media] v4l2-dev/ioctl.c: add vb2_queue support to video_device

2012-07-06T20:30:54+00:00

This prepares struct video_device for easier integration with vb2. It also introduces a new lock that protects the vb2_queue. It is up to the driver to use it or not. And the driver can associate an owner filehandle with the queue to check whether queuing requests are permitted for the calling filehandle.

[media] v4l2-dev.c: add debug sysfs entry

2012-07-06T20:25:31+00:00

Since this could theoretically change the debug value while in the middle of v4l2-ioctl.c, we make a copy of vfd->debug to ensure consistent debug behavior. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-dev.c: fix g_parm regression in determine_valid_ioctls()

2012-06-11T21:11:40+00:00

The field current_norm does not have to be set for g_parm to be a valid ioctl. Remove that check, but add a check whether this is a video node instead as g_parm only makes sense for those nodes. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
