free_buff_list and rec_buff_list are initialized in the middle of hdpvr_probe(),
but if something bad happens before that, error handling code calls hdpvr_delete(),
which contains iteration over the lists (via hdpvr_free_buffers()).
The patch moves the lists initialization to the beginning and by the way fixes
goto label in error handling of registering videodev.

The image data is laid out a bit more weirdly and thus needs more work to
properly interlace. What we get from hardware is V4L2_FIELD_ALTERNATE, but
since userspace support for it is practically nonexistent, thus we make
V4L2_FIELD_INTERLACED from it so that it's more easily interpreted.

Commit 1c1d86a1ea ("[media] v4l2: always require v4l2_dev,
rename parent to dev_parent") expects v4l2_dev to be always set.
It converted most of the drivers using the parent field of video_device
to v4l2_dev field. G2D driver did not set the parent field. Hence it got
left out. Without this patch we get the following boot warning and G2D
driver fails to register the video device.

VIDIOC_TRY_FMT and VIDIOC_S_FMT that should be de-duped. Also, video

This patch changes the firmware file names of the FIMC-IS subsystem.
It is needed since there are different firmwares used across various
SoC series, e.g. Exynos4 and Exynos5.
Also the sensor specific "setfile" name is changed, to account for
it depends on an image sensor and is also specific to the FIMC-IS
and the SoC.
This is a change for a driver merged in 3.10.

Add compatible property for the Exynos5250 and enable the frame start
and frame end interrupts. These interrupts are needed for the Exynos5
FIMC-IS firmware. The driver enables those interrupt only where available,
depending on the 'compatible' property. This can be optimized further,
by exposing some API at the subdev driver, so the host driver can enable
extra interrupts only for the image processing chains involving FIMC-IS.

This patch adds support for the Exynos5250 SoC variant of the FIMC-LITE
IP. A 'compatible' string is added for Exynos5250 compatible devices
and the capture DMA handling is reworked to use the FLITE_REG_CIFCNTSEQ
register, masking output DMA buffer address slots. The frame interrupt
is enabled so there are now 2 interrupts per frame. This likely can be
optimized in future by using any status registers that allow to figure
out what the last and the currently written frame buffer is. It would
also be more reliable in cases where there are high interrupt service
latencies.

Several functions in the sh_mobile_ceu_camera driver implement generic
algorithms and can be re-used by other V4L2 camera host drivers too. These
functions attempt to optimise scaling and cropping functions of the
subdevice, e.g. a camera sensor. This patch makes those functions generic
for future re-use by other camera host drivers.

Add support for asynchronous subdevice probing, using the v4l2-async API.
The legacy synchronous mode is still supported too, which allows to
gradually update drivers and platforms. The selected approach adds a
notifier for each struct soc_camera_device instance, i.e. for each video
device node, even when there are multiple such instances registered with a
single soc-camera host simultaneously.

Currently bridge device drivers register devices for all subdevices
synchronously, typically, during their probing. E.g. if an I2C CMOS sensor
is attached to a video bridge device, the bridge driver will create an I2C
device and wait for the respective I2C driver to probe. This makes linking
of devices straight forward, but this approach cannot be used with
intrinsically asynchronous and unordered device registration systems like
the Flattened Device Tree. To support such systems this patch adds an
asynchronous subdevice registration framework to V4L2. To use it respective
(e.g. I2C) subdevice drivers must register themselves with the framework.
A bridge driver on the other hand must register notification callbacks,
that will be called upon various related events.

It is often useful to have simple means to get from a subdevice to the
underlying physical device. This patch adds such a pointer to struct
v4l2_subdev and sets it accordingly in the I2C and SPI cases.

Typical video devices like camera sensors require an external clock source.
Many such devices cannot even access their hardware registers without a
running clock. These clock sources should be controlled by their consumers.
This should be performed, using the generic clock framework. Unfortunately
so far only very few systems have been ported to that framework. This patch
adds a set of temporary helpers, mimicking the generic clock API, to V4L2.
Platforms, adopting the clock API, should switch to using it. Eventually
this temporary API should be removed.
