On 32-bits archs, a signed integer has 31 bits plus on extra
bit for signal. Due to that, touching the 32th bit with something
like:
int bar = 1 << 31;
has an undefined behavior in C on 32 bit architectures, as it
touches the signal bit. This is warned by cppcheck.
Instead, force the numbers to be unsigned, in order to solve this
issue.

Switch all media platform drivers to call v4l2_async_notifier_add_subdev()
to add asd's to a notifier, in place of referencing the notifier->subdevs[]
array. These drivers also must now call v4l2_async_notifier_init() before
adding asd's to their notifiers.
There may still be cases where a platform driver maintains a list of
asd's that is a duplicate of the notifier asd_list, in which case its
possible the platform driver list can be removed, and can reference the
notifier asd_list instead. One example of where a duplicate list has
been removed in this patch is xilinx-vipp.c. If there are such cases
remaining, those drivers should be optimized to remove the duplicate
platform driver asd lists.
None of the changes to the platform drivers in this patch have been
tested. Verify that the async subdevices needed by the platform are
bound at load time, and that the driver unloads and reloads correctly
with no memory leaking of asd objects.

When the subdevice doesn't provide s_power core ops callback, the
v4l2_subdev_call for s_power returns -ENOIOCTLCMD. If the subdevice
doesn't have the special handling for its power saving mode, the s_power
isn't required. So -ENOIOCTLCMD from the v4l2_subdev_call should be
ignored.
Actually the -ENOIOCTLCMD is ignored in this driver's suspend/resume,
but the others treat the -ENOIOCTLCMD as an error.
This prepares a wrapper function to ignore -ENOIOCTLCMD and replaces
all s_power calls with it.
This also adds warning message when s_power() is failed.

The open() operation for the pxa_camera driver always calls s_power()
operation to put its subdevice sensor in normal operation mode, and the
release() operation always call s_power() operation to put the subdevice
in power saving mode.
This requires the subdevice sensor driver to keep track of its power
state in order to avoid putting the subdevice in power saving mode while
the device is still opened by some users.
Many subdevice drivers handle it by the boilerplate code that increments
and decrements an internal counter in s_power() like below:
/*
* If the power count is modified from 0 to != 0 or from != 0 to 0,
* update the power state.
*/
if (sensor->power_count == !on) {
ret = ov5640_set_power(sensor, !!on);
if (ret)
goto out;
}
/* Update the power count. */
sensor->power_count += on ? 1 : -1;
However, some subdevice drivers don't handle it and may cause a problem
with the pxa_camera driver if the video device is opened by more than
two users at the same time.
Instead of propagating the boilerplate code for each subdevice driver
that implement s_power, this introduces an trick that many V4L2 drivers
are using with v4l2_fh_is_singular_file().

The V4L2_ASYNC_MATCH_FWNODE match criteria requires just one
struct to be filled (struct fwnode_handle). The V4L2_ASYNC_MATCH_DEVNAME
match criteria requires just a device name.
So, it doesn't make sense to enclose those into structs,
as the criteria can go directly into the union.
That makes easier to document it, as we don't need to document
weird senseless structs.
At drivers, this makes even clearer about the match criteria.

The async subdev notifier .bound(), .unbind() and .complete() operations
are function pointers stored directly in the v4l2_async_subdev

The conversion from soc_camera omitted a correct handling of the clock
gating for a sensor. When the pxa_camera driver module was removed it
tried to unregister clk, but this caused a similar warning:
WARNING: CPU: 0 PID: 6740 at drivers/media/v4l2-core/v4l2-clk.c:278
v4l2_clk_unregister(): Refusing to unregister ref-counted 0-0030 clock!
The clock was at time still refcounted by the sensor driver. Before
the removing of the pxa_camera the clock must be dropped by the sensor
driver. This should be triggered by v4l2_async_notifier_unregister() call
which removes sensor driver module too, calls unbind() function and then
tries to probe sensor driver again. Inside unbind() we can safely
unregister the v4l2 clock as the sensor driver got removed. The original
v4l2_clk_unregister() should be put inside test as the clock can be
already unregistered from unbind(). If there was not any bound sensor
the clock is still present.
The codepath is practically a copy from the old soc_camera. The bug was
tested with a pxa_camera+ov9640 combination during the conversion
of the ov9640 from the soc_camera.

Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.

Since we really don't want to have to use any of the soc-camera code this patch
copies the relevant code and data structures from soc_mediabus and renames it to pxa_mbus_*.
The large table of formats has been culled a bit, removing formats that are not supported
by this driver.

warnings. The generated code is not affected.

As the conversion to a v4l2 standalone device is finished, move
pxa_camera one directory up and finish severing any dependency to
soc_camera.
