Randy Dunlap d5c00762ec [media] media: fix gspca drivers build dependencies
Several (15) drivers in media/usb/gspca use IF_ENABLED(CONFIG_INPUT)
to decide if they should call input* interfaces, but those drivers
do not build successfully when CONFIG_INPUT=m and the gspca drivers
are builtin (=y).  Making USB_GSPCA depend on INPUT || INPUT=n
fixes the build dependencies and allows all of them to build
cleanly.

Fixes these build errors (selections, not all are listed):

Luca Bonissi 91de062f50 [media] gspca_vc032x: Fix wrong bytesperline
I found a problem on vc032x gspca usb webcam subdriver: "bytesperline"
property is wrong for YUYV and YVYU formats.
With recent v4l-utils library (>=0.9.1), that uses "bytesperline" for
pixel format conversion, the result is a wrong jerky image.

Patch tested on my laptop (USB webcam Logitech Orbicam 046d:0892).

Joe Howse 0f5b265762 [media] gspca: Add high-speed modes for PS3 Eye camera
Add support in the PS3 Eye driver for QVGA capture at higher
frame rates: 187, 150, and 137 FPS. This functionality is valuable
because the PS3 Eye is popular for computer vision projects and no
other camera in its price range supports such high frame rates.

Correct a QVGA mode that was listed as 40 FPS. It is really 37 FPS
(half of 75 FPS).

Tests confirm that the nominal frame rates are achieved.

Laurent Pinchart d52e238136 [media] v4l: Support extending the v4l2_pix_format structure
The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.

To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.

The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.

To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

Hans Verkuil 0d5e8c4313 [media] Fix 64-bit division fall-out from 64-bit control ranges
Commit 0ba2aeb6da increased the internal control ranges
to 64 bit, but that caused problems in drivers that use the minimum/maximum/step/default_value
control values in a division or modulus operations since not all architectures support
those natively.

Luckily, in almost all cases it is possible to just cast to 32 bits (the control value
is known to be 32 bits, so it is safe to cast). Only in v4l2-ctrls.c was it necessary to
use do_div in one function.

Antonio Ospite 2fe152451d [media] gspca: provide a mechanism to select a specific transfer endpoint
Currently gspca selects the first ISOC input endpoint as the input
transfer endpoint, however some devices can provide streams on endpoints
different then the first one, so some subdrivers (e.g. gspca_kinect) may
want to select a specific endpoint to use as a transfer endpoint.

Add an xfer_ep field to struct gspca_dev, and change alt_xfer() so that
it accepts a parameter which represents a specific endpoint address to
look for.

If a subdriver wants to specify a value for gspca_dev->xfer_ep it can do
that in its sd_config() callback.

The sn9c102 driver is deprecated. It was moved to staging in
anticipation of its removal in a future kernel version. However, USB
devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when
both sn9c102 and gspca_sonixb are enabled.

We must migrate all the users of these devices to the gspca_sonixb
driver now, so that it gets sufficient testing before the sn9c102

Vladik Aranov 15807765d8 [media] gscpa_ov534_9: Add support for ov3610 sensor
Dear Hans de Goede, I have Ubuntu (raring) and recently bought digital
microscope eyepiece Lomo MD300. It is the same device as Future Optics MVV3000.
Unfortunately it does not work out of box. Moreover drivers refused to work
under Windows 7 as well leaving me only with Win Xp working system. I have had
no choice but to examine what happened in USB bus and attempt to reproduce the
sequence. So, i have download the source(3.8.0-30 kernel) and made required
changes to driver to make my hardware work.
I submit my changed files to you as maintainer of the driver so you can
integrade my changes into main stream. Thanx. Hopefully my Ubuntu will work
with my hardware out of box.
Sincerely yours Vladik Aranov

Ondrej Zary 4ab0620bdc [media] introduce gspca-stk1135: Syntek STK1135 driver
Hello,
this is a new gspca driver for Syntek STK1135 webcams. The code is completely
new, but register values are based on Syntekdriver (stk11xx) by Nicolas VIVIEN
(http://syntekdriver.sourceforge.net).
Only one webcam type is supported now - vendor 0x174f, device 0x6a31.
It's Asus F5RL laptop flippable webcam with MT9M112.
The camera works better than in Windows - initializes much faster and
provides more resolutions (the sensor can do almost any resolution - just
add it to the stk1135_modes[] - could this feature be somehow used by
applications to avoid SW scaling?).
Autoflip works too - when the camera is flipped around, the image is flipped
automatically.
