As reported by hermann pitton <hermann-pitton@arcor.de>, some devices
has a different chip id for em2710 (likely the older ones):
em28xx: New device @ 480 Mbps (eb1a:2710, interface 0, class 0)
em28xx #0: Identified as EM2710/EM2750/EM2751 webcam grabber (card=22)
em28xx #0: em28xx chip ID = 17

em28xx doesn't have temporal scaling. However, on webcams, sensors are
capable of changing the output rate. So, VIDIOC_[G|S]_PARM ioctls should
be passed to the sensor for it to properly set frame rate.

Implement g_parm/s_parm ioctls. Those are used to check the current
frame rate (in fps) and to set it to a value. In practice, there are
only 15 possible different speeds, due to chip limits.

We have support for radio on saa7133/35/31e cards with tda8290/8275(a)
and 5.5MHz ceramic filter on the bridge chips since a while.
It was previously not tested, if this card supports it too, but the old
"ghost" radio with wrong filters doesn't work anymore.
Thanks go to Pham Thanh Nam and Laszlo Kustan for reporting it working
on that input.

Register 0x13 seems to be a sort of image control, maybe gamma. Lower
values produce better images, while higher values increases the contrast
and shifts colors to green. 0xff produces a black image.
If this register is left alone, a random value can be found at the
register, producing weird results.
This register doesn't seem to affect tv streams.

Silvercrest mt9v011 sensor produces a 640x480 image. However,
previously, the code were getting only half of the lines and merging two
consecutive frames to "produce" a 640x480 image.
With the addition of progressive mode, now em28xx is working with a full
image. However, when the number of lines is bigger than 240, the
beginning of some odd lines are filled with blank.
After lots of testing, and physically checking the device for a Xtal, it
was noticed experimentally that mt9v011 is using em28xx XCLK as its
clock. Due to that, changing XCLK value changes the maximum speed of the
stream.
At the tests, it were possible to produce up to 32 fps, using a 30 MHz
XCLK. However, at that rate, the artifacts happen even at 320x240. Lower
values of XCLK produces artifacts only at 640x480.
At some values of xclk (for example XCLKK = 6 MHz, 640x480), it is
possible to see an invalid sucession of artifacts with this pattern:
.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
(where the dots represent the blanked pixels)
So, it seems that a waveform in the format of a ramp is interferring at
the image.
The cause of this interference is currently unknown. Some possibilities
are:
- electrical interference (maybe this device is broken?);
- some issue at mt9v011 programming;
- some bug at em28xx chip.
So, for now, let's be conservative and use a value of XCLK that we know
for sure that it won't cause artifacts.
As I'm waiting for more of such devices with different em28xx chipset
revisions, I'll have the opportunity to double check the issue with
other pieces of hardware.
Later patches can vary XCLK depending on the vertical resolutions, if a
proper fix is not discovered.

em28xx_pre_card_setup() is meant to contain board-specific initialization. Also,
as autodetection sometimes occur only after having i2c bus enabled, this
function may need to be called later.
Moving those setups to happen outside the function avoids calling it twice without
need and without duplicating output lines at dmesg.

without it
From: Mauro Carvalho Chehab <mchehab@redhat.com>
V4L2 API (chapter 1.5) states that:
Drivers must implement all input ioctls when the device has one
or more inputs, all output ioctls when the device has one or more outputs.
When the device has any audio inputs or outputs the driver must set the
V4L2_CAP_AUDIO flag in the struct v4l2_capability returned by the
VIDIOC_QUERYCAP ioctl.
So, devices without audio input should return -EINVAL.

A user discovered that the Geniatech x8000 encountered a regression when
the xc3028 power management was introduced. The xc3028 never recovers after
setting the powerdown register, which is probably because the xc3028 reset
GPIO is not properly configured. Since I do not have access to the hardware
and thus cannot determine the correct GPIO configuration, just disable xc3028
power management on this board, which fixes the regression.
Thanks to user "ritec" for reporting the issue and testing the fix.

We need to implement the g_std call, or else the default norm always gets
returned, which breaks VBI capturing if you had changed the standard to NTSC
using s_std.
I had temporarily changed the default norm to NTSC so that zvbi-ntsc-cc
wouldn't choke, so now that we are returning the correct value, switch it back
to PAL as the default.

Add support for raw VBI capture for the em28xx bridge, currently only for
NTSC. Support for PAL capture to follow shortly (including the removal of
numerous hard-coded NTSC-specific sizes for capture buffers, etc).
Note that the code currently changes the default current norm from PAL to
NTSC (so that zvbi-ntsc-cc works properly). The default norm really should
be moved into a board-level parameter.

Add code enabling the VBI registers for variants of the em28xx chip that
support VBI, and make sure the isoc streaming code continues to work for
the video component of the stream (note the video and vbi data arrive
intermixed on the same isoc pipe).
Note that this version just drops the actual VBI data onto the floor as
opposed to processing it. The "#ifdef 0" tags are for the videobuf code that
appears in the next patch in this series.
We created a separate version of the isoc_copy version for parsing the version
of the stream that includes VBI data. In theory, they might be able to be
merged at some point in the future, but the initial goal is to ensure that we
do not cause any regressions with devices that do not have VBI support.
