Debugging cleanups to the zr36067 driver:
* Use module_param_named() to declare the debug parameter, so we can
use a single global variable to handle the debug level. This makes
the driver a bit smaller (by 648 bytes on x86_64), thanks to one
less level of indirection on every use.
* Change the debug parameter sysfs permissions, so that the debug
level can be adjusted at runtime, as is done in many other
media/video drivers.
* The debug level is between 0 and 5, not 0 and 4.
* Move the zr_debug export and dprintk macro definition to a header
file so that we don't have to define them in each source file.
* Simplify a duplicate test on zr_debug.
Note that zr_debug was subsequently renamed to debug_zr36067 to avoid
possible conflicts with other Zoran device drivers, on a suggestion
by Trent Piepho.

Right now the composite sound input doesn't work on AverTV 307 because of
the wrong mux setup. The composite sound is routed via an external
4channel multiplexer controlled by GPIO, while the code assumes an internal
multiplexer instead.

Due to a documentation bug (the type mask is 3 bits long, not 2) the wrong
frame types were filled in: the B and P frame types were swapped.
This bug also hid a second bug: when a capture is stopped a last entry is
written into the pgm index buffer with internal type 0, denoting the end
of the program. This entry wasn't ignored, instead it was accidentally
returned to the caller as a P frame.

fails, then we'll bail out and return -ENOMEM.
The problem is that in that case we don't free the storage allocated

Configuring the OLPC camera requires something over 150 register
writes. Unfortunately, querying the CAFE i2c controller too
soon after a write causes the hardware to flake. The problem had
been "solved" with an msleep() call, but, between the number of
registers and how msleep() behaves, that resulted in a 3-second
delay on camera initialization. Instead, we hand-code a wait for
the completion interrupt which avoids reading the status registers.

Various gpio and mux settings for the Osprey 440 weren't correct. Fix them
and provide some documentation about how the gpios work.
The osprey eeprom routine wasn't run for the 440, add it. It was also crap,
re-written to be better.
Add the Osprey 440 to the Bt878 ALSA driver's whitelist. Currently the sample
rate is fixed at 32kHz, as the driver doesn't support different rates for
digital input mode, though the card can select the rate from 32, 44.1, or 48
kHz via gpio.
Setting the audio gain via ALSA isn't supported yet; a userspace tool that
programs the X9221 via i2c-dev must be used.
The Bt878 digital audio format isn't programmed correctly for the CS5331A ADC
used, resulting in extremely garbled sound. That is fixed in a followup

When raw capture was turned off, the current capturing frame (v4l_grab_frame)
wasn't reset to NO_GRAB_ACTIVE. If capture was turned back on, the driver
would think this frame was currently being captured, and wait for it to
complete before starting a new frame. The hardware on the other hand would
not be actively capturing a frame. The result was the driver would wait
forever for v4l_grab_frame to be captured.
Some calls to zr36057_set_memgrab(0) were missing spin-locks, which have been
added.

Add support for the UYVY and the other big endian output formats. The
driver was naming formats based on the host endianess. This is different
that all the other drivers appear to work and not what software appears
to expect.
Use ARRAY_SIZE() to find the the size of the zoran_formats array.
Change the way the driver handles setting the video format register. Rather
than use some if and switch statements to set to register by looking at the
format id, the format list simply has a field with the proper bits to set.
Adds a bit of ifdef to make a driver without V4L1 support more possible.
Also create a macro for defining formats that handles vl41 and/or vl42
support to avoid repeated ifdefs in the format list.

The driver was returning the size of the (fixed) buffer it allocated as the
sizeimage field in the v4l2 pixel format, rather than the actual size of the
image. For example, a 192x128 YUYV image is 49152 bytes but the driver would
always return 131072 bytes since if that was the size of the v4l buffer.
This violates the v4l2 spec, which says that sizeimage should be the actual
size of the image for uncompressed formats. It also caused mplayer to crash.

During uncompressed capture, the poll() function was looking the wrong frame.
It was using the frame the driver was going to capture into next (pend_tail),
when it should have been looking at the next frame to be de-queued with
DQBUF/SYNC (sync_tail).
It also wasn't looking in the right spot. It was looking at the file handle's
copy of the buffer status, rather than the driver core copy. The interrupt
routine marks frames as done in the driver core copy, the file handle copy
isn't updated. So even if poll() looked at the right frame, it would never
see it transition to done and return POLLIN.
The compressed capture code has this same problem, looking in fh->jpg_buffers
when it should have used zr->jpg_buffers.
There was some logic to detect when there was no current capture in process
nor any frames queued and try to return an error, which ends up being a bad
idea. It's possible to call select() from one thread while no capture is in
process, or no frames queued, and then start a capture or queue frames from
another thread.
The buffer state variables are protected by a spin lock, which the code wasn't
acquiring. That is fixed too.

The zr36067 driver doesn't make a distinction between the different sub-types
of NTSC, PAL, or SECAM norms. For example, when the enum std ioctl returns
the PAL standard it returns PAL_BG|PAL_DK|PAL_H|PAL_I.
When setting the norm, it required the bitmask to match exactly the set of
norms used during the enumeration. If just one norm was specified, for
example PAL_BG or NTSC_M, it would fail. This violates the V4L2 spec,
"VIDIOC_S_STD accepts *one* or more flags..."
The key thing to realize is that V4L2_STD_PAL is not one bit, it is multiple
bits. It's ok to call S_STD with any *one* of those bits, but the driver was
requiring *all* of them.
This fixes the S_STD function so that it will accept any set of one or more
PAL norms as PAL, and the same for NTSC and SECAM.
