Mauro Carvalho Chehab 531c98e718 V4L/DVB (9953): em28xx: Add suport for debugging AC97 anciliary chips
The em28xx driver can be coupled to an anciliary AC97 chip. This patch
allows read/write AC97 registers directly.

The zoom controls move the zoom lens group to a an absolute position, as a

This patch adds a V4L2_CAP_SENSOR_UPSIDE_DOWN flag to the capabilities flags,
and sets this flag for the Philips SPC200NC cam (which has its sensor installed

fixes the upside down display with the SPC200NC cam.

David Woodhouse 5e6b83ed8c Fix header export of videodev2.h, ivtv.h, ivtvfb.h
The exported copy of videodev2.h contains this line:

	#define #include <sys/time.h>

This is because for some reason it defines __user for itself -- despite
the fact that we remove all instances of __user when exporting headers.
_All_ pointers in userspace are user pointers. Fix it by removing the
unnecessary '#define __user' from the file.

The new headers ivtv.h and ivtvfb.h would have the same problem... if
whoever put them there had actually remembered to add them to the Kbuild
file while he was at it. Fix those too, and export them as was
presumably intended.

Note that includes of <linux/compiler.h> are also stripped by the header
export process, so those don't need to be conditional.

But there was no warning in Documentation/feature-removal-schedule.txt
and I'm receiving reports that it's breaking userspace apps (the
gstreamer-v4l2 plugin breaks in Fedora rawhide). You can't just pull
things from the published userspace API like that.

Please can we revert the addition of _DEPRECATED to these ioctl
definitions. Perhaps we can add a runtime warning if they actually get
used? Or a compile-time warning if we can manage that?

Remove a section containing basically ideas for future sliced VBI standards.
This can be resurrected should any of this be actually implemented. For now
it only pollutes this header file.

Hans Verkuil 4f828ef7f3 V4L/DVB (5181): Sliced VBI API no longer marked experimental.
The Sliced VBI API is no longer marked experimental. Introduced in 2.6.14
and with only a single modification in 2.6.19 I think we can consider this
API to be solid.

Trent Piepho e7b58f5259 V4L/DVB (5162): Change VIDIOC_DBG_[SG]_REGISTER ioctls' reg address to 64 bits
Maybe someday there will be a device with a register address space >
32-bits, or maybe an i2c device which uses a protocol > 4 bytes long to
address its registers.

Trent Piepho 52ebc763d8 V4L/DVB (5146): Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal only
The direct register access ioctls were defined as kernel internal only,
but they are very useful for debugging hardware from userspace and are
used as such.  Officially export them.

VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER 
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h 
to videodev2.h.

Types used in struct v4l2_register are changed to the userspace 
exportable versions (u32 -> __u32, etc). 

Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move 
the check into the video_ioctl2() dispatcher so it doesn't need to be 
duplicated in each driver's call-back function. CAP_SYS_ADMIN check is 
added to pvrusb2 (which doesn't use video_ioctl2).
