SN9C10x driver updates.
The most important change is the addition of the "SN9C10x" vendor-specific
pixel format, which is used by the applications or libraries to get "raw"
compressed data from the SN9C10x controllers. This also means that V4L2 should
be smart enough for the decompression to be handled in userland. You can
consider this patch as a further response to the discussion we had on the lkml
about the submission of the PWC driver including decompression in kernelspace,
which is present in the Alan Cox's tree.
Changes: (+ new, - removed, * cleanup, @ bugfix)
@ Fix VIDIOC_TRY_FMT ioctl
@ Fix SOF/EOF problems with TAS5130D1B image sensor
@ Fix VIDIOC_ENUM_FMT ioctl
* Replace wait_event_interruptible() with wait_event_timeout()
* Use msecs_to_jiffies() for timeouts in jiffies
* Use usb_make_path() on VIDIOC_QUERYCAP for device path in the usb tree
* read() returns buf.bytesused instead of buf.length on success
- Remove brightness control from PAS106B and PAS202BCB, since it has no effect
on the active pixel area (it's just for window border lines)
+ Implement VIDIOC_G_PARM and VIDIOC_S_PARM ioctl's
+ Add DAC magnitude, DAC sign, green balance and exposure controls for PAS106B
and PAS202BCB image sensors
+ Add an additional pixel format for compressed video: V4L2_PIX_FMT_SN9C10X
+ VIDIOC_S_JPEGCOMP and VIDIOC_G_JPEGCOMP are used to set or get the current
compression quality
+ New documentation note in "Notes for V4L2 application developers" paragraph
about video formats and compressed data.
+ Documentation updates about the new features

The following patchlet to videodev2.h brings in the "__user" definition from
linux/compiler.h, making it suitable for inclusion in both kernel or user
code.

The patch just removes all trailing whitespaces, there are no actual code
changes. I've a script to remove them from my sources now, that should kill
those no-op whitespace changes in my patches after merging this initial
cleanup.

This patch has some minor updates to v4l2 API:
* A new pixel format (V4L2_PIX_FMT_SBGGR8).
* Adds some #defines for tv norms for convenience.
* Allow to specify the video source to capture from on a per-frame basis.

The VIDIOC_CROPCAP ioctl had wrong R/W bits, this patch fixes it.

From: Gerd Knorr <kraxel@bytesex.org>
This patch is a v4l2 update. Changes:
* added new ioctls (VIDIOC_G_PRIORITY, VIDIOC_S_PRIORITY) to give v4l apps
priorities for tuning and other controls. Main purpose is that backgrounds
applictions like nxtvepg which are fishing informations from /dev/vbi
(teletext, epg, ...) can run at lower priority than interactive tv apps and
thus the user isn't annonyed with unexpected channel switches.
* add a set of helper functions to handle priorities to the v4l2-common
module.
* minor fixes in the v4l1-compat module.
* minor header file fixes.

From: Gerd Knorr <kraxel@bytesex.org>
This patch fixes some v4l2 ioctl #defines which have wrong _IO* macros. It
also adds a function which maps the old numbers to to new ones to maintain
binary backward compatibility.

[ GregKH has already done this is USB and PCI core. ]
From: "Warren A. Layton" <zeevon@debian.org>
Based on a request from Matthew Wilcox, convert instances of
pci_dev->slot_name to use pci_name() instead:
"In order to support PCI Domains, we have to stop using slot_name.
It's related to driver model transition too since pci_dev->slot_name
was redundant with pci_dev->dev.bus_id. So I introduced the inline
function pci_name(). Now there's about 300-400 places in the tree
that're using slot_name which need to be converted to use pci_name().
once that's done, we can remove the slot_name pointer in pci_dev and
save a (void *) per pci_dev."

This adds the v4l2 API to the linux kernel.
The first, original video4linux API has a number of design bugs. They
are fixed in this new API revision. It already exists for quite some
time. Last weeks it got a number of cleanups based on the experiences
of the last years (drop stuff nobody uses, fix some inconsistencies).
We consider it being in a pretty good shape now and like to see it in
2.6.
This patch is basically the header file with all the structs and ioctls
in there. A small module with some helper functions for v4l2 drivers is
included too. Related updates (bttv, ...) will follow as separate
patches.
