[media] v4l2-ctrls: Fix control enumeration for multiple subdevs with ctrl
v4l2-ctl and qv4l2 enumerate controls using V4L2_CTRL_FLAG_NEXT_CTRL,
falling back to the old method if the flag isn't supported.
The v4l2_subdev_queryctrl function will currently handle that flag, but
for the controls of the subdev only. This isn't right, it should refuse
this flag, otherwise v4l2-ctl will only see the controls of the first
subdev.

Subdev controls return codes are evil, as they return -EINVAL to mean
both unsupported and invalid arguments. Due to that, we need to use a
trick to identify what controls are supported by a subdev.
tuner-core has no business to do with digital TV. So, don't use
T_DIGITAL_TV on it, as it has no code to distinguish between
them, and nobody fills T_DIGITAL_TV right.
tda9887 used to use the T_STANDBY type internally, while tea5761
used it to put the device to sleep. Fix the code for it to work
properly with the tuner core changes and remove this flag from
tuner.h.
Remove the now obsolete set_freq. Also merge set_addr and set_type_addr.
In the past, it used to have two different setup calls, one to set just
the tuner type to any tuner found, and another to set the type only if
the address matches. Those two internal calls were grouped together,
but the functions weren't merged, making the code uglier.
[media] tuner-core: Don't use a static var for xc5000_cfg
A static var is evil, especially if a device has two boards with
xc5000. Instead, just like the other drivers, use stack to store
its config during setup.
[media] tuner-core: Some cleanups at check_mode/set_mode
Properly document those functions and do some cleanups around that.
There's just one behavior change on this patchset: it will now restore
TV frequency when changing from radio to TV mode.
[media] tuner-core: Reorganize the functions internally
This is a big patch with no functional changes. It just
rearranges everything inside the driver, and prepares to
break TV and Radio into two separate fops groups.
Currently, it has an heuristics logic to determine if the
call came from radio or video. However, the caller driver
knows for sure, so tuner-core shouldn't try to guess it.
[media] cx88: Don't allow opening a device while it is not ready
After registering the cdev, it would be possible do have an open on it.
In a matter of fact, some versions of udev do this. So, move registration
to the end and protect it with a mutex.
[media] cx231xx: Allow some boards to not use I2C port 3
Some devices don't need to use it. So allow to just disable this logic.
Having it enabled on some devices cause power management to complain,
generating error -71.
[media] cx231xx: Use parameters to describe some board variants
Instead of per-model tests all over the code, use some parameters
at the board entries to describe the model variants for:
- devices with 417 MPEG encoder;
- devices that use external AV;
- devices where vbi VANC endpoint doesn't work;
- devices with xc5000 that require different IF
initialization (and probably will cover also
xc3028).
- devices with xceive tuner that require a reset
during init.
[media] cx231xx: Use a generic check for TUNER_XC5000
The check for xc5000 assumes that the tuner will always
be using the same bus and will have the same address.
As those are configurable via dev->board, it should use,
instead, the values defined there.
Also, a similar type of test will be needed by other
tuners (for example, for TUNER_XC2028)
[media] cx231xx: Simplify interface checking logic at probe
Just a cleanup patch. Removes one indent level by moving
the return -ENODEV to happen before the device register
logic, if the interface is not the audio/video (int 1).
[media] saa7134: Properly report when a board doesn't have eeprom
When a device is not detected, the driver prints a warning message.
That's ok, except for the fact that, even on newer devices that have
eeprom but aren't yet supported, it prints a message saying that the
device doesn't have eeprom.
Fix it by having a separate message for devices with eeprom, but not
yet known by the driver.

This driver is abusing the kernel<=>userspace API, due to the lack of a
proper solution for it. A discussion were done at:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg22196.html
But there's not a solution for it yet. So, move the driver to staging, while
we don't have a final solution.
