The AUDIO_AC3_BITRATE control is still missing from this list, but such
optional controls are a bit hard to handle. This will be fixed automatically
when we switch to the control framework.

drivers/ieee1394/ has been removed in Linux 2.6.37. The corresponding
backend code in firedtv is no longer built in now and can be deleted.
Firedtv continues to work with drivers/firewire/.
Also, fix a Kconfig menu comment: Removal of CONFIG_IEEE1394 made the
"Supported FireWire (IEEE 1394) Adapters" comment disappear; bring it back
with corrected dependency.

Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
type of R/W arguments. They were fixed, but the old ioctl names are
still there, maintained to avoid breaking binary compatibility:
There's no sense on preserving those forever, as it is very doubtful
that someone would try to use a such old binary with a modern kernel.
Removing them will allow us to remove some magic done at the V4L ioctl
handler.
Note that any application compiled with a videodev2.h from 2.6.7 or later
will be using the correct ioctls.

This is a complete rewrite of the old v4l1 vicam subdriver, featuring
multiple resolutions, gain + exposure control and still has less code.
Oh and it is a v4l2 driver rather then v4l1 ofcourse :)

donating his 3com homeconnect to me, which made this rewrite possible.

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.

Having the device detection happening at reset is bad, as every time,
it will produce a message like:
tvp5150 2-005c: tvp5150am1 detected.
This only polutes the log and for an accidental kernel hacker, it looks
like a real problem. So, move those printk's to happen during device
probe.

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.

Power down tuners at suspend. At resume, if the tuner is in standby,
calls set_mode, that will turn it on and set the latest frequencies.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
In the past, T_STANDBY were used on devices with a separate radio tuner to
mark a tuner that were disabled. With the time, it got newer meanings.
Also, due to a bug at the logic, the driver might incorrectly return
T_STANDBY to userspace.
So, instead of keeping the abuse, just use a boolean for storing
such information.
We can't remove T_STANDBY yet, as this is used on two other drivers. A
latter patch will address its usage outside tuner-core.

TV frequency when changing from radio to TV mode.

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.

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.
