I updated and simplyfied patch from Zbynek Hrabovsky for recent kernel.
It enables autodetection of card, sound in analog TV , sound in FM radio
and switching between antenna and cable RF input. Radio tuner still
doesn't work, I don't even know how it works. Some guys wrote me that FM
radio works with TV tuner used instead of radio part (symlink video0 ->
radio0).

From: Hans Verkuil <hverkuil@xs4all.nl>
The v4l core supplies default handlers for G_STD and G_PARM. However, both
default handlers are buggy.
This patch fixes the following:
1) If no g_std is supplied and current_norm == 0, then this driver does not
support TV video standards (e.g. a radio or webcam driver). Return
-EINVAL. This ensures that there is no bogus VIDIOC_G_STD support for
such drivers.
2) The default VIDIOC_G_PARM handler used current_norm instead of first
checking if the driver supported g_std and calling that to get the norm.
It also didn't check if current_norm was 0, since in that case the driver
does not support TV standards (or no standard was set at all) and the
default handler should return -EINVAL.
Note that I am very unhappy with these default handlers: I think they
basically behave like some very strange and unexpected side-effect.

Drivers should either set current_norm or supply a g_std callback.
The hdpvr driver does neither. Since it initializes to a 60 Hz format
I've initialized the current_norm to NTSC | PAL_M | PAL_60 which is the
60 Hz subset of tvnorms.

We don't know the xtal frequency of Silvercrest, but we need to have
some value in order to allow controlling the frame rate frequency. The
value is probably still wrong, since the manufacturer announces this
device as being capable of 30fps, but the maximum we can get is
13.5 fps.

Due to historical reasons, em28xx driver gets two consecutive frames and
fold them into an unique framing, doing interlacing. While this works
fine for TV images, this produces two bad effects with webcams:
1) webcam images are progressive. Merging two consecutive images produce
interlacing artifacts on the image;
2) since the driver needs to get two frames, it reduces the maximum
frame rate by two.

em28xx doesn't have temporal scaling. However, on webcams, sensors are
capable of changing the output rate. So, VIDIOC_[G|S]_PARM ioctls should

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.

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.
