Mauro Carvalho Chehab d78757e780 [media] videobuf2-core: Add it to device-drivers DocBook
Most of the stuff at videobuf2-core are ok for adding it to
DocBook.

Two notes here:
1) As videobuf2-core will be soon be changed, better to
   not spend too much efforts right now, as things will
   change soon;

2) struct vb2_queue has a number of private elements that are
   documented. As Kernel nano documentation format handles
   "private:" arguments, we need to put them on a separate
   comment block or to remove. Keeping the comments is
   obviously better ;)

Mauro Carvalho Chehab b84aeb03a8 [media] v4l2-subdev: reorder the v4l2_subdev_video_ops comments
The comments for struct v4l2_subdev_video_ops are out of the
order as the parameter would appear at struct. This is not
a problem for DocBook, but humans find harder to mentally
reorder ;)

So, put them at the right order. That makes easier to check
what's missing, and to put the comments in the right place.

Pull media fixes from Mauro Carvalho Chehab:

 - a regression fix at the videobuf2 core driver

 - fix error handling at mantis probing code

 - revert the IR encode patches, as the API is not mature enough.
   So, better to postpone the changes to a latter Kernel

 - fix Kconfig breakages on some randconfig scenarios.

Lars-Peter Clausen 8ae5640f1b [media] Add helper function for subdev event notifications
Add a new helper function called v4l2_subdev_notify_event() which will
deliver the specified event to both the v4l2 subdev event queue as well as
to the notify callback. The former is typically used by userspace
applications to listen to notification events while the later is used by
bridge drivers. Combining both into the same function avoids boilerplate
code in subdev drivers.

Sakari Ailus 6d058c5643 [media] vb2: Only requeue buffers immediately once streaming is started
Buffers can be returned back to videobuf2 in driver's streamon handler. In
this case vb2_buffer_done() with buffer state VB2_BUF_STATE_QUEUED will
cause the driver's buf_queue vb2 operation to be called, queueing the same
buffer again only to be returned to videobuf2 using vb2_buffer_done() and so
on.

Add a new buffer state VB2_BUF_STATE_REQUEUEING which, when used as the
state argument to vb2_buffer_done(), will result in buffers queued to the
driver. Using VB2_BUF_STATE_QUEUED will leave the buffer to videobuf2, as it
was before "[media] vb2: allow requeuing buffers while streaming".

Prashant Laddha 5fea1bb703 [media] v4l2-dv-timings: add support for reduced blanking v2
Added support for reduced blanking version 2 (RB v2) in cvt timings.
Standard specifies a fixed vsync pulse of 8 lines to indicate RB v2
timings. Vertical back porch is fixed at 6 lines and vertical front
porch is remainder of vertical blanking time.

For RB v2, horizontal blanking is fixed at 80 pixels. Horizontal sync
is fixed at 32. All horizontal timing counts (active pixels, front,
back porches) can be specified upto a precision of 1.

RB v2 allows for non standard aspect ratios. In RB v2 vsync does not
indicate aspect ratio. In absence of aspect ratio v4l2_detect_cvt()
cannot calculate image width from image height. Hence extending the
v4l2_detect_cvt() to pass image width in case of RB v2.
