2009-01-02V4L/DVB (10141): v4l2: debugging API changed to match against driver name ↵Hans Verkuil
instead of ID. Since the i2c driver ID will be removed in the near future we have to modify the v4l2 debugging API to use the driver name instead of driver ID. Note that this API is not used in applications other than v4l2-dbg.cpp as it is for debugging and testing only. Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged with a warning that it is deprecated and will be removed in 2.6.30.

2009-01-02V4L/DVB (10138): v4l2-ioctl: change to long return type to match unlocked_ioctl.Hans Verkuil
Since internal to v4l2 the ioctl prototype is the same regardless of it being called through .ioctl or .unlocked_ioctl, we need to convert it all to the long return type of unlocked_ioctl. Thanks to Jean-Francois Moine for posting an initial patch for this and thus bringing it to our attention.

2009-01-02V4L/DVB (10135): v4l2: introduce v4l2_file_operations.Hans Verkuil
Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.

__video_ioctl2 This patch fixes this warning: drivers/media/video/gspca/gspca.c:1811: warning: initialization from incompatible pointer type The reason is that the returned argument should be a long, not an integer. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-29V4L/DVB (9578): v4l core: add support for enumerating frame sizes and intervalsMauro Carvalho Chehab
video_ioctl2 lacks implementation of those two ioctls: - VIDIOC_ENUM_FRAMESIZES and VIDIOC_ENUM_FRAMEINTERVALS Adds implementation for those. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-29V4L/DVB (9503): v4l: remove inode argument from video_usercopyHans Verkuil
The inode argument was never used. Removing it from video_usercopy brings the function pointer type of video_usercopy in line with similar v4l2 functions, thus simplifying several drivers. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-10-21V4L/DVB (9331): Remove unused inode parameter from video_ioctl2Mauro Carvalho Chehab
inode is never used on video_ioctl2. Remove it and rename the function to __video_ioctl2. This allows its usage directly as a callback at fops.unlocked_ioctl. Since we still need a callback with inode to be used with fops.ioctl, this patch adds video_ioctl2() that is just a call to __video_ioctl2(). Also, this patch adds some comments about video_ioctl2 and __video_ioctl2 usage at v4l2-ioctl.h. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-10-21V4L/DVB (9330): Get rid of inode parameter at v4l_compat_translate_ioctl()Mauro Carvalho Chehab
The inode parameter at v4l_compat_translate_ioctl() were just passed over several places just to keep compatible with fops.ioctl. However, it weren't used anywere. This patch gets hid of this unused parameter. Cc: Laurent Pinchart <laurent.pinchart@skynet.be> Cc: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-10-13V4L/DVB (9160): v4l: remove vidioc_enum_fmt_vbi_capHans Verkuil
Remove the vidioc_enum_fmt_vbi_cap ops: it was scheduled for removal in 2.6.28 since the v4l2 specification says that V4L2_BUF_TYPE_VBI_CAPTURE should not support VIDIOC_ENUM_FMT. It's also pretty pointless. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-09-03V4L/DVB (8629): v4l2-ioctl: do not try to handle private V4L1 ioctlsHans Verkuil
Some drivers (e.g. zoran) have private V4L1 ioctls. Do not try to pass them to v4l1_compat_translate because then the driver will never see them. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-07-26V4L/DVB (8482): videodev: move all ioctl callbacks to a new v4l2_ioctl_ops ↵Hans Verkuil
struct All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it. This ensures a clean separation between the const ops struct and the non-const video_device struct.

v4l2-common.h or v4l2-ioctl.h The functions in a header should not belong to another module. The prio functions belong to v4l2-common.c, so move them to v4l2-common.h. The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header and move those functions to it.
