This patch drops the _ACTIVE part from the selection target names
as a prerequisite to unify the selection target names across the subdev
and regular video node API.
The meaning of V4L2_SEL_TGT_*_ACTIVE and V4L2_SUBDEV_SEL_TGT_*_ACTUAL
selection targets is logically the same. Different names add to confusion
where both APIs are used in a single driver or an application. For some
system configurations different names may lead to interoperability issues.
For backwards compatibility V4L2_SEL_TGT_CROP_ACTIVE and
V4L2_SEL_TGT_COMPOSE_ACTIVE are defined as aliases to V4L2_SEL_TGT_CROP
and V4L2_SEL_TGT_COMPOSE. These aliases will be removed after deprecation
period, according to Documentation/feature-removal-schedule.txt.

There is getting more entities to manage within single video pipeline
in newer SoCs. To simplify code put subdevs' pointer into an array
rather than adding new member in struct fimc_pipeline for each subdev.
This allows to easier handle subdev operations in proper order.
Additionally walk graph in one direction only in fimc_pipeline_prepare()
function to make sure we properly gather only media entities that below
to single data pipeline. This avoids wrong initialization in case where,
for example there are multiple active links from s5p-mipi-csis subdev
output pad.
struct fimc_pipeline declaration is moved to the driver's public header
to allow other drivers to reuse the fimc-lite driver added in subsequent
patches.

In order to be able to select only FIMC-LITE support, which is added
with subsequent patches, the regular FIMC support is now contained
only in fimc-core.c, fimc-m2m.c and fimc-capture.c files. The graph
and pipeline management is now solely handled in fimc-mdevice.[ch].
This means the FIMC driver can now be excluded with Kconfig option,
leaving only FIMC-LITE and allowing this driver to be reused in SoCs
that have only FIMC-LITE and no regular FIMC IP.

This used to be the default if the lock pointer was set, but now that lock is by
default only used for ioctl serialization. Those drivers that already used
core locking have this flag set explicitly, except for some drivers where
it was obvious that there was no need to serialize any file operations other
than ioctl.
The drivers that didn't need this flag were:
drivers/media/radio/dsbr100.c
drivers/media/radio/radio-isa.c
drivers/media/radio/radio-keene.c
drivers/media/radio/radio-miropcm20.c
drivers/media/radio/radio-mr800.c
drivers/media/radio/radio-tea5764.c
drivers/media/radio/radio-timb.c
drivers/media/video/vivi.c
sound/i2c/other/tea575x-tuner.c
The other drivers that use core locking and where it was not immediately
obvious that this flag wasn't needed were changed so that the flag is set
together with a comment that that driver needs work to avoid having to
set that flag. This will often involve taking the core lock in the fops
themselves.
Eventually this flag should go and it should not be used in new drivers.
There are a few reasons why we want to avoid core locking of non-ioctl
fops: in the case of mmap this can lead to a deadlock in rare situations
since when mmap is called the mmap_sem is held and it is possible for
other parts of the code to take that lock as well (copy_from_user()/copy_to_user()
perform a down_read(&mm->mmap_sem) when a page fault occurs).
It is very unlikely that that happens since the core lock serializes all
fops, but the kernel warns about it if lock validation is turned on.
For poll it is also undesirable to take the core lock as that can introduce
increased latency. The same is true for read/write.
While it was possible to make flags or something to turn on/off taking the
core lock for each file operation, in practice it is much simpler to just
not take it at all except for ioctl and leave it to the driver to take the
lock. There are only a handful fops compared to the zillion ioctls we have.
I also wanted to make it obvious which drivers still take the lock for all
fops, so that's why I chose to have drivers set it explicitly.

On Exynos SoCs the FIMC IP allows to configure globally the alpha
component of all pixels for V4L2_PIX_FMT_RGB32, V4L2_PIX_FMT_RGB555
and V4L2_PIX_FMT_RGB444 image formats. This patch adds a v4l2 control
in order to let the applications control the alpha component value.
The alpha value range depends on the pixel format, for RGB32 it's
0..255 (8-bits), for RGB555 - 0..1 (1-bit) and for RGB444 - 0..15
(4-bits). The v4l2 control range is always 0..255 and the alpha
component data width is determined by currently set format on the
V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE buffer queue. The applications
need to match the alpha channel value range and the pixel format
since the driver will clamp the alpha component. Depending on
fourcc the valid alpha bits are:
- V4L2_PIX_FMT_RGB555 [0]
- V4L2_PIX_FMT_RGB444 [3:0]
- V4L2_PIX_FMT_RGB32 [7:0]
When switching to a pixel format with smaller alpha component width
the currently set alpha value will be clamped to maximum value valid
for current format. When switching to a format with wider alpha the
alpha value remains unchanged.
The variant description data structure is extended with a new entry
so an additional control is created only where really supported by
the hardware.
V4L2_PIX_FMT_RGB555 and V4L2_PIX_FMT_RGB444 formats are only valid
for V4L2_BUF_TYPE_VIDEO_CAPTURE buffer queue.

When requested more than 2 buffers the buffer dequeue order was wrong
due to erroneous updating FIMC registers in every interrupt handler
call. This also fixes regression of resetting the output DMA buffer
pointer at wrong time, when some buffers are already queued in hardware.
The hardware is reset in the start_streaming callback in order to align
the H/W state with the software output buffer pointer (buf_index).
Additionally a simple write to S5P_CISCCTRL register is replaced with
a read/modification/write to make sure the scaler is not being disabled
in fimc_hw_set_scaler().

Add support for transparent DMA transfer of JPEG data with MIPI-CSI2
USER1 format. In JPEG mode the color effect, scaling and cropping
is not supported as well as image rotation and flipping thus these
controls are marked as inactive if V4L2_PIX_FMT_JPEG pixel format
was selected.

Add a subdev to expose the host's scaling and composition functions.
The camera frame composition onto an output buffer may be configured
through set/get_crop at FIMC.{n} source pad.
Additionally allow crop, composition and controls to be modified
during streaming. Make sure the default format is set when opening
the video capture node.
Rename struct fimc_vid_cap::fmt to more relevant 'mf' to avoid
confusion.

In the camera capture driver use fimc_pipeline_* calls provided by
the media device driver part, in place where v4l2_subdev_call() were
used. This way the capture driver don't need to differentiate between
various H/W pipeline setups, i.e. if the MIPI-CSI receiver subdev is
used or not.
Remove the sync_capture_fmt() function instead of which
fimc_pipeline_try_format() is introduced in the following patch adding
the FIMC capture subdev.
The TRY_FMT ioctl function is completed by a subsequent patch adding
the capture subdev, so the try_fmt routines can be reused in the subdev
and the video node ioctl handlers.

Replace fimc_find_format() and find_mbus_format() with single function
that can return a pointer to the private format description based
on fourcc, media bus code or index in the table.
Create separate VIDIOC_ENUM_FMT ioctl handlers for video capture
and mem-to-mem video node. This is needed because some formats are
valid only for the video capture and some only for the mem-to-mem
video node.

Convert the v4l controls code to use the new control framework.
fimc_ctrls_activate/deactivate functions are introduced for the
transparent DMA transfer mode (JPEG), where the rotation and flipping
controls are not supported.
The capture video node does not inherit sensors' controls when the
subdevs are configured by the user space (user_subdev_api == true).
However by default after the driver's initialization
the 'user-subdev_api' flag is false and any sensor controls will
also be available at the video node.
When the pipeline links are disconnected through the media device
the FIMC and any sensor inherited controls are destroyed and then
again created when the pipeline connection completes.

This is a prerequisite for the patch converting the driver to use
the control framework. As the capture driver does not use per file
handle contexts, two separate ioctl handlers are created for it
(vidioc_try_fmt_mplane, and vidioc_g_fmt_mplane) so there is no
handlers shared between the memory-to-memory and capture video node.

Currently there is a v4l2_device instance being registered per each
(capture and memory-to-memory) video node created per FIMC H/W instance.
This patch is a prerequisite for using the top level v4l2_device
instantiated by the media device driver.
To retain current debug trace semantic (so it's possible to distinguish
between the capture and m2m FIMC) the video_device is used in place
of v4l2_device where appropriate.
