In cases where the device does not actually provide a USB audio class *or*
vendor audio, do not load the driver that provides vendor audio support (such
as the KWorld 2800d). Otherwise, the /dev/audio1 device file gets created and
users get confused.
Also, reworks the logic a bit so that we don't try to inspect the register
content if the register read failed entirely.

Since i2c autoprobing is no longer supported by v4l2 we need to make sure
that the i2c modules are linked before the v4l2 modules. The v4l2 modules
now rely on the presence of the i2c modules, so these must have initialized
themselves before the v4l2 modules.
The exception is the ir-kbd-i2c module, which is the only one still using
autoprobing. This one should be loaded at the end of the v4l2 module. Loading
it earlier actually causes problems with tveeprom. Once ir-kbd-i2c is no
longer autoprobing, then it has to move up as well.
This is only an issue when everything is compiled into the kernel.
Thanks to Marcus Swoboda for reporting this and Udo Steinberg for testing
this patch.

Fix a regression caused by changeset 9133:64aed7485a43 - v4l: disconnect
kernel number from minor
Before the above changeset, ov511_probe used to allow forcing to use a
certain specific set of video devices, like:
modprobe ov511 unit_video=4,1,3 num_uv=3
So, assuming that you have 5 ov511 devices, and connect they one by one,
they'll gain the following device numbers (at the connection order):
/dev/video4
/dev/video1
/dev/video3
/dev/video0
/dev/video2
However, this was changed due to this change at video_register_device():
+ nr = find_next_zero_bit(video_nums[type], minor_cnt, nr == -1 ? 0 : nr);
With the previous behavior, a trial to register on an already allocated mirror
would fail, and a loop would get the next requested minor. However, the current
behavior is to get the next available minor instead of failing. Due to that,
this means that the above modprobe parameter will give, instead:
/dev/video5
/dev/video6
/dev/video7
/dev/video8
/dev/video9
In order to restore the original behavior, a static var were added,
storing the amount of already registered devices.
While there, it also fixes the locking of the probe/disconnect functions.

The frontend attachment code didn't handle cases where the frontend
partially failed to attach. For instance, when the demod was attached
successfully but the tuner driver wasn't compiled or fails to init for some
reason. In these cases we try to clean up the partial attachment and fail
instead of proceeding with a broken frontend.
If frontend registration fails, clean up with dvb_frontend_detach() rather
than just calling the frontend's main release method. The former does some
additional stuff, like release an attached tuner and take care of putting
symbols when dynamic binding is used.
In skystar2_rev23_attach() it's not necessary to set fc->dev_type, that

A bunch of V4L drivers generate BTN_0 instead of KEY_CAMERA key presses.
X11 is able to handle KEY_CAMERA automatically these days while BTN_0 is
not treated at all. Thus it would be of big benefit if the camera drivers
would consistently generate KEY_CAMERA. Some drivers (uvc) already do,
this patch updates the remaining drivers to do the same.
I only possess a limited set of webcams, so this isn't tested with all

Let card drivers probe for IR receiver devices and instantiate them if
found. Ultimately it would be better if we could stop probing
completely, but I suspect this won't be possible for all card types.
There's certainly room for cleanups. For example, some drivers are
sharing I2C adapter IDs, so they also had to share the list of I2C
addresses being probed for an IR receiver. Now that each driver
explicitly says which addresses should be probed, maybe some addresses
can be dropped from some drivers.
Also, the special cases in saa7134-i2c should probably be handled on a
per-board basis. This would be more efficient and less risky than always
probing extra addresses on all boards. I'll give it a try later.

Most UVC camera include an interrupt endpoint to report control value changes,
video streaming errors and camera button events. The USB controller
continuously polls the interrupt endpoint to retrieve such events. This
prevents the device from being auto-suspended, and thus consumes power.
Reporting video streaming errors don't make sense when the V4L2 device is
closed. Control value changes are probably useless as well if nobody listens to
the events, although caching will probably have to be completely disabled then.
No polling is thus be required when /dev/videoX is not opened.
To enable auto-suspend and save power do not poll the interrupt endpoint until
the device is open. We lose the ability to detect button events if no
application is using the camera.

dibusb_i2c_xfer seems to do things very dangerous :
it assumes that it get only write/read request or write request.
That means that read can be understood as write. For example a program
doing
file = open("/dev/i2c-x", O_RDWR);
ioctl(file, I2C_SLAVE, 0x50)
read(file, data, 10)
will corrupt the eeprom as it will be understood as a write.

The em28xx actually has a register that tells the driver what the maximum
packet size is (based on a value programmed into the eeprom). Make use of
that register instead of assuming a hardcoded value of 564 (since 564 is not
correct for devices that do QAM such as the KWorld 340u).
Note that for now the em2874 code isn't there, falling back to the 564 value,
however this is not a problem since there are not any em2874 based devices in
the current v4l-dvb tree).
Thanks to Jarod Wilson for detecting the initial problem and figuring out that
the isoc configuration was wrong for his device.

According to the engineer at PCTV Systems, the xc5000 reset pin is supposed
to be on GPIO12. However, despite three nights of effort, pulling that GPIO
low didn't reset the xc5000. While pulling MO_SRST_IO low does reset the
xc5000, this also resets in the s5h1409 being reset as well. This causes
tuning to always fail since the internal state of the s5h1409 does not match
the driver's state.
Given that the only two conditions in which the driver performs a reset is
during firmware load and powering down the chip, I am taking out the reset.
We know that the chip is being reset when the cx88 comes online, and not being
able to do power management for this board is better than not having any
tuning at all.
Problem discovered when implementing proper power management for the xc5000,
which results in calls to the reset callback *after* s5h1409 is initialized.

Instead of polling at 100ms intervals for register writes, poll at 5ms
intervals. This is consistent with the xc5000 specification, and improves
tuning time by up to 500 ms on devices that such as the au0828 which do not
properly implement i2c clock stretching (since the five register writes that
occur for a tuning request often do not complete immediately but do complete
far before 100ms has gone by).
The net amount of time we wait before timing out is unchanged (500ms).

The C99 specification states in section 6.11.5:
The placement of a storage-class specifier other than at the
beginning of the declaration specifiers in a declaration is an
obsolescent feature.

Getting QVGA to be supported on the po1030 seems harder than I first thought. I need access to the proper hardware in order to fix it up.

mt9m111: Hflip and vflip shall always be 0 at start and the image shall be correctly aligned.
The mt9m111 is hflipped and vflipped by default. Correct the semantics to make this happen.

Toggle the AI1 mux when changing the CX18_AUDIO_ENABLE register. It's hard to
reliably tell when we have written to this register successfully unless we
change some bits we know we can read back. The AI mux bits always read back
what we wrote to them, so force them to toggle whenever we have to write to
the register, so we can tell we wrote to the register successfully.
This change was prompted by users experiencing broadcast audio decoding
problems after the cx18 module loads for the first time.

Add code to verify the cx18-av-core digitizer firmware loads correctly. The
verification function reads back and compares the firmware bytes loaded
into the A/V core. The result of the verification is only used to log a
message in the system log.
This change was prompted by users with multiple card setups that have problems
with broadcast audio decoding the first time the cx18 module is loaded.

Both the MPEG-2 SVCD stream format and the MPEG-2 DVD stream format should
use an MPEG-2 PS container. This makes it safe to stuff IVTV Private Stream 1
VBI packets in these stream types using the existing cx18 driver routines.

Simplify the way outgoing work handler gets scheduled to send empty buffers
back to the firmware for use. Also reduced the memory required for scheduling
this outgoing work, by using a single, per stream work object.

To avoid sleeps in providing buffers to user space and in handling incoming
buffers from the capture unit, converted the per stream mutex for locking
queues to 3 spin locks. There is now a spin lock per queue
to increase concurrency when moving buffers around.
Also simplified queue manipulations and buffer handling of incoming buffers
of data from the capture unit.

When sending an outgoing firmware command, prepare to wait before we raise the
interrupt, so we don't miss the wake_up() on the acknowledgment. When waiting
for the acknowledgement, there is no need to loop around schedule(), as there
will only be one interrupt, and hence one wake_up(), issued.

This change defers sending all CX18_CPU_DE_SET_MDL commands, for a stream with
an ongoing capture, by adding a work queue to handle sending such commands when
needed. This prevents any sleeps, caused by notifying the firmware of new
usable buffers, when a V4L2 application read() is being satisfied or when
an incoming buffer is processed by the cx18-NN-in work queue thread.

Rename the work queue to "in_work_queue" to indicate it is handling

With the transition of soc-camera to become a platform driver and to the
v4l2-subdev framework the initialisation order becomes important. In case
of a static build clients (i2c) drivers have to be available when host
drivers are probed. Moving host drivers down in the Makefile achieves the
desired order.

Currently pcm990 camera bus-width management functions request a GPIO and never
free it again. With this approach the GPIO extender driver cannot be unloaded
once camera drivers have been loaded, also unloading theb i2c-pxa bus driver
produces errors, because the GPIO extender driver cannot unregister properly.
Another problem is, that if camera drivers are once loaded before the GPIO
extender driver, the platform code marks the GPIO unavailable and only a reboot
helps to recover. Adding an explicit free_bus method and using it in mt9m001
and mt9v022 drivers fixes these problems.
