ff69786b4c V4L/DVB (12258): em28xx: fix typo in mt352 init sequence for Terratec Cinergy T XS USB
Andy walls pointed out that we were passing 0x5d to the TUNER_GO register,
instead of 0x01.  Set the register properly (note the code did still work with
the incorrect value, so this does not address a regression).

Thanks to Andy Walls for noticing the issue.

579d315218 V4L/DVB (12244): em28xx: adjust vinmode/vinctl based on the stream input format
Depending on the video input format, vinmode/vinctl needs adjustments.
For TV, this is not relevant, since the supported decoders output data
at the same format. However, webcam sensors may have different formats,
so, this needs to be adjusted based on the device.

d36bb4e772 V4L/DVB (12243): em28xx: allow specifying sensor xtal frequency
In order to properly estimate fps, mt9v011 sensor driver needs to know
what is the used frequency on the sensor cristal. Adds the proper fields
and initialization code for specifying the cristal frequency.

Also, based on experimentation, it was noticed that the Silvercrest is
outputing data at 7 fps. This means that it should be using a 6.3 MHz
cristal. This information needs to be double checked later, by opening
the device. Anyway, by using this value for xtal, at least now we have
the correct fps report.

e11206e67f V4L/DVB (12240): mt9v011: add a function to calculate frames per second rate
It is possible to adjust the fps rate by changing some register values.
This is function of the connected Xtal at the camera sensor, being a 27
MHz cristal needed, in order to support 640x480 at 30 fps.

For now, it will only calculate the values for fps. Later patches may
introduce V4L2 ioctls, to allow frequency rate adjustments.

5569996421 V4L/DVB (12239): em28xx: fix webcam scaling
While trying to fix an mt9v001 webcam, I noticed that HSCALE/VSCALE do
work with em28xx + webcam. The issue is that the scaling setup depends
on the number of visible rows/cols of the input image.

With mt9v011 (Silvercrest), the resolution is 640x480. So, the scaling
is different from a normal TV image (720x480 on NTSC). This were causing
a wrong scaling and a previous patch disabled scaling.

As each sensor have their different resolution setting, the xres/yres
should be adjusted accordingly with the input sensor.

b04fb66152 V4L/DVB (12238): em28xx: call sensor detection code for all webcam entries
With the previous approach, autodetection were working only for the two
generic entries (em275x and em2820 unknown ones). So, if someone would
try to force probing an specific device, the code would not properly run
the autodetection code.

With the new approach, the sensor autodetection will be run not only for
the two generic entries, but also do webcam specific ones.

In the TRY_FMT handler the function get_scale() is called to find what the
scaler hardware will produce for a requested size.

The problem is that get_scale(struct cx231xx *dev, ..., unsigned int *vscale,
unsigned int *hscale) saves the calculated scale values into both the
pointer arguments and into dev's hscale and vscale fields.  TRY_FMT shouldn't
actually change anything in the device state.

The code to in get_scale() that writes to dev->[hv]scale can just be
deleted.  In all cases when dev's fields should be modified, get_scale()
was called with get_scale(dev, ..., &dev->hscale, &dev->vscale), so dev was
getting updated anyway.

This didn't actually cause a problem because nothing ever actually made use
of the hscale and vscale fields.  I changed cx231xx_resolution_set() to use
those fields rather than re-calculate them with a call to get_scale().

Updating [hv]scale in cx231xx_resolution_set() isn't necessary because
every call of cx231xx_resolution_set() was already preceded by a call to
get_scale() or setting the [hv]scale fields, so they will be always be
up-to-date w.r.t. width and height.

Removing the call to get_scale() from cx231xx_resolution_set() allowed
making get_scale() a static function, which is a good thing for something
with such a short name.  There is already another function with the same
name in the em28xx driver, but that one is static.

The v4l function has a better algorithm for aligning image size.

It appears that the em2800 can only scale by 50% or 100%, i.e. the only
heights supported might be 240 and 480.  In that case the old code would
set any height other than 240 to 480.  Request 240 get 240, but request 239
and then you get 480.  Change it to round to the nearest supported value.

b0d3159be9 V4L/DVB (11901): v4l2: Create helper function for bounding and aligning images
Most hardware has limits on minimum and maximum image dimensions and also
requirements about alignment.  For example, image width must be even or a
multiple of four.  Some hardware has requirements that the total image size
(width * height) be a multiple of some power of two.

v4l_bound_align_image() will enforce min and max width and height, power of
two alignment on width and height, and power of two alignment on total
image size.

It uses an efficient algorithm that will try to find the "closest" image
size that meets the requirements.

a6862da2f3 V4L/DVB (12119): pvrusb2: Re-fix hardware scaling on video standard change
The cx25840 module's VBI initialization logic uses the current video
standard as part of its internal algorithm.  This therefore means that
we probably need to make sure that the correct video standard has been
set before initializing VBI.  (Normally we would not care about VBI,
but as described in an earlier changeset, VBI must be initialized
correctly on the cx25840 in order for the chip's hardware scaler to
operate correctly.)

It's kind of messy to force the video standard to be set before
initializing VBI (mainly because we can't know what the app really
wants that early in the initialization process).  So this patch does
the next best thing: VBI is re-initialized after any point where the
video standard has been set.

e17d787c51 V4L/DVB (12118): pvrusb2: Fix hardware scaling when used with cx25840
The cx25840 module requires that its VBI initialization entry point be
called in order for hardware-scaled video capture to work properly -
even if we don't care about VBI.  Making this behavior even more
subtle is that if the capture resolution is set to 720x480 - which is
the default that the pvrusb2 driver sets up - then the cx25840
bypasses the hardware scaler.  Therefore this problem does not
manifest itself until some other resolution, e.g. 640x480, is tried.
MythTV typically defaults to 640x480 or 480x480, which means that
things break whenever the driver is used with MythTV.

This all has been known for a while (since at least Nov 2006), but
recent changes in the pvrusb2 driver (specifically in regards to
sub-device support) caused this to break again.  VBI initialization
must happen *after* the chip's firmware is loaded, not before.  With
this fix, 24xxx devices work correctly again.

A related fix that is part of this changeset is that now we
re-initialize VBI any time after we issue a reset to the cx25840
driver.  Issuing a chip reset erases the state that the VBI setup
previously did.  Until the HVR-1950 came along this subtlety went
unnoticed, because the pvrusb2 driver previously never issued such a
reset.  But with the HVR-1950 we have to do that reset in order to
correctly transition from digital back to analog mode - and since the
HVR-1950 always starts in digital mode (required for the DVB side to
initialize correctly) then this device has never had a chance to work
correctly in analog mode!  Analog capture on the HVR-1950 has been
broken this *ENTIRE* time.  I had missed it until now because I've
usually been testing at the default 720x480 resolution which does not
require scaling...  What fun.  By re-initializing VBI after a cx25840
chip reset, correct behavior is restored.

Mark the v4l1 ov511 as deprecated as we now have ov511 support in
the gspca ov519 driver. Note we should really also keep track of this
in Documentation/feature-removal-schedule.txt, but that is not
part of the v4l-dvb tree.

ov511: remove ov518 usb id's from the driver, as they have not been working
ever since the decompression code got removed from the kernel, and they
are no supported by the gspca_ov519 module.

f5cee95c2e V4L/DVB (12078): gspca_ov519: Better default contrast for ov6630
Hmm, another one with an extra if (life sucks) the
default contrast really is no good for the ov6630, it
isn't even high enough in full daylight, this gives
the ov6630 a different initial value for a better out
of the box experience.

80142efa71 V4L/DVB (12077): gspca_ov519: Fix 320x240 with ov7660 sensor
As reported on the ov51x-jpeg list, and as I can confirm with my own cam
the ov7670 in 320x240 has a number of broken columns of pixels
at the left of the picture. This was not present in the old
driver as it always used 640x480 and did software
downscaling (took me a while to figure that one out).
The fix adds a sensor specific if in so far sensor
neutral code :( But this is the only way to fix this,
this cannot be fixed by only changing sensor registers.

My ov519 cam has it led inverted, the same has been
reported on the ov51x-jpeg list for another
creative cam. This patch fixes this without changing
the behaviour for other cams.
