      V4L/DVB: Deprecate cpia driver (used for parallel port webcams) · 7af97eff
      Mauro Carvalho Chehab authored 
      
cpia driver were re-written inside gspca driver, for USB devices. The only
functionality that were not migrated is the support for parallel port,
as:
	1) the developer didn't find any hardware;
	2) it doesn't  seem important to keep support for a parallel port webcam,
	   as this is an obsolete technology;
	3) the changes at gspca for it to work with parallel port would be very large;
	4) this driver still uses BKL.

So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody
cares enough to port parallel port support to gspca or to create a new driver
that uses the same gspca-cpia sub-driver.

      V4L/DVB: saa5246a/saa5249: Remove obsolete teletext drivers · 563711f1
      Hans Verkuil authored 
      
These old i2c teletext drivers are not supported by any hardware and cannot be
tested anymore.

Note that while the mxb board seemingly used the saa5246a driver, in reality
this teletext driver never worked.

These drivers are removed as part of the vtx feature removal, originally
scheduled for 2.6.35.

      V4L/DVB: v4l2: Add new control handling framework · 0996517c
      Hans Verkuil authored 
      
Add a new framework to handle controls which makes life for driver
developers much easier.

Note that this patch moves some of the control support that used to be in
v4l2-common.c to v4l2-ctrls.c. The tables were copied unchanged. The body
of v4l2_ctrl_query_fill() was copied to a new v4l2_ctrl_fill() function
in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl
struct anymore, which makes it more general.

The remainder of v4l2-ctrls.c is all new. Highlights include:

- No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL,
  S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers
  or subdevs. New wrapper functions are provided that can just be plugged in.
  Once everything has been converted these wrapper functions can be removed as well.

- When subdevices are added their controls can be automatically merged
  with the bridge driver's controls.

- Most drivers just need to implement s_ctrl to set the controls.
  The framework handles the locking and tries to be as 'atomic' as possible.

- Ready for the subdev device nodes: the same mechanism applies to subdevs
  and their device nodes as well. Sub-device drivers can make controls
  local, preventing them from being merged with bridge drivers.

- Takes care of backwards compatibility handling of VIDIOC_S_CTRL and
  VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent.
  CTRL_CLASS controls are automatically added.

      V4L/DVB: v4l: Add driver for Samsung S5P SoC video postprocessor · 5fd8f738
      Sylwester Nawrocki authored 
      
This driver exports a video device node per each camera interface/
video postprocessor (FIMC) device contained in Samsung S5P SoC series.
The driver is based on v4l2-mem2mem framework.
