A recent patch didn't take into account that frontends can be compiled into
the kernel. Or that frontends compiled as modules can't be used by the
b2c2 driver if it is not a module itself.
Some frontends require multiple drivers, e.g. a demod driver and a tuner
driver. The code for the frontend support was getting added if the demod
driver was available. Change this to also require any needed tuner or SEC
drivers as well.

When the change was introduced in the zl10353 for the i2c gate behavior, this
broke the HVR-900 which was not behind a gate. Use a version of the zl10353
config profile that indicates the tuner is not behind such a gate.
Without this patch the first tune succeeds, but subsequent tuning attempts
will fail.
The change also renames the terratec zl10353 profile I wrote to be more
generic, since it is shared by the non-terratec device.

In cases where the device has a generic Empia USB ID, the call in the
precard setup phase did not set the tuner GPIO. As a result, the tuner may
not be taken out of reset before attempting initialization in the analog
driver.
This problem was not seen before with the EVGA inDtube, since that particular
board has the analog GPIO setup to include taking the tuner out of reset.

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.

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.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
Since frames per second is a function of cristal frequency, and this is

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.

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.

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.

Instead of using em28xx board decoder field for storing sensor information,
let's use instead a separate field for it.
Also, as sensors are currently autodetected, there's no need of having
it at the boards description. So, move it to the main em28xx struct.

There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent
he loop counter is of type 'unsigned char' and it should count to 128.
The compiler will incorrectly decide that a trivial loop like this:
unsigned char i, ...
for (i = 0; i < 128; i++) {
..
is endless, and will compile it to a single instruction that just
branches to itself.
This was triggered by the addition of '-fno-strict-overflow', and we
could play games with compiler versions and go back to '-fwrapv'
instead, but the trivial way to avoid it is to just make the loop
induction variable be an 'int' instead.

A pointer to mac_sonic_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
Various other functions that are called by mac_sonic_probe need to move
to .devinit.text, too.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.
