Fix the following to get RAW10 formats working:
In rvin_formats, the bpp is set to 4 for RAW10. As VIN unpacks RAW10 to
16-bit containers, the bpp should be 2.
Don't set VNDMR_YC_THR to the VNDMR register. The YC_THR is "YC Data
Through Mode", used for YUV formats and should not be set for RAW10.

When shutting down capture extra care was needed to try and complete a
buffer that was involved in the emulated support for SEQ_{TB,BT}. This
was needed as a buffer might be queued once to the driver, but two times
to the hardware using different offsets.
As support for SEQ_{TB,BT} is now removed this shutdown process can be
greatly simplified. And in addition the state keeping of the VIN device
can be reduced to a single boolean value instead of keeping track of
this SEQ_{TB,BT} stopping dance.

The STARTING state is superfluous and can be replaced with a check of
the sequence counter. The design idea is that the first buffer returned
from the driver have to come from the first hardware buffer slot.
Failing this the first 3 buffers queued to the device can be returned
out-of-order.
But it's much clearer to check the sequence counter to only return the
first buffer if it comes from hardware slot 0 then it is to carry around
an extra state just for this. Remove the unneeded state and replace it
with a simpler check.

The VIN state of suspended is superfluous. The logic was that when the
device were suspended and in a RUNNING state the state was set to
SUSPENDED. And when resuming it checked if the state is SUSPENDED and if
so started the device and changed it to RUNNING.
This can be avoided by simply checking if the device is in a RUNNING
state at both suspend and resume callbacks. Remove the unneeded
complexity.

When the driver was converted from soc_camera software support for
V4L2_FIELD_SEQ_TB and V4L2_FIELD_SEQ_BT were added. This was done by
capturing twice to the same VB2 buffer, but at different offsets.
This turned out to be a bad idea and it never really worked properly in
all situations. As the hardware can't support this mode natively remove
trying to emulate it in software. It's still possible to capture TOP or
BOTTOM fields separately or both ALTERNATING. If user-space wants the
same fields in the same buffer the same hack to capture twice to the
same buffer can be done.
Removing this error prone emulated support pave ways in future work to
simplify the internal buffer handling and making it less fragile, while
enabling adding support for other features the hardware actually
supports.

Earlier versions of the datasheet where unclear about the stride setting
for RAW8 capture formats. Later datasheets clarifies that the stride
only process in this mode for non-image data. For image data the full
stride shall be used. Compare section "RAW: 8 Bits and Embedded 8-Bit
Non-Image Data, User Defined 8-bit Data" vs "RAW: 8 Bits".
Remove the special case from pixel formats that carry image data and
treat it as any other image format.

Since commit 88785982a19d ("media: vb2: use lock if wait_prepare/finish
are NULL") it is no longer needed to set the wait_prepare/finish
vb2_ops callbacks as long as the lock field in vb2_queue is set.
Since the vb2_ops_wait_prepare/finish callbacks already rely on that field,
we can safely drop these callbacks.
This simplifies the code and this is a step towards the goal of deleting
these callbacks.

Some R-Car SoCs are capable of capturing RAW10. Extend the format
enumeration, validation and setup to expose and configure for this
format if the particular device supports it.
The VIN is usually capable of converting from most media bus formats to
a range of different pixel formats. However if the input media bus
format is a RAW10 format this is not possible so the corresponding pixel
output format is forced.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/media to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

The YUYV8_1X16 and UYVY8_1X16 formats are treated as 'ITU-R
BT.601/BT.1358 16-bit YCbCr-422 input' (YUV16 - 0x5) in the R-Car VIN
driver and are thus disallowed when capturing frames from the R-Car
CSI-2 interface according to the hardware manual.
As the 1X16 format variants are meant to be used with serial busses they
have to be treated as 'YCbCr-422 8-bit data input' (0x1) when capturing
from CSI-2, which is a valid setting for CSI-2.
Commit 78b3f9d75a62 ("media: rcar-vin: Add check that input interface
and format are valid") disallowed capturing YUV16 when using the CSI-2
interface. Fix this by using YUV8_BT601 for YCbCr422 when CSI-2 is in
use.

The rcar-csi2 driver was added before the platform/renesas directory
existed and since it was used together in a pipeline with the rcar-vin
driver it was located together with it.
The rcar-isp driver can also be used together with the rcar-csi2 driver
in a pipeline that is terminated by the rcar-vin driver. However by the
time rcar-isp was added the platform/renesas directory existed so it was
added there.
To remove the confusion that the rcar-csi2 driver have code dependencies
on the rcar-vin driver move it to the same directory level as the
rcar-isp driver. This makes it clear they are three distinct drivers
that can be used together in a pipeline, but do not depend on each
other.

Additionally drivers/media/i2c/s5k5baf.c and
drivers/media/platform/samsung/s3c-camif/camif-capture.c have been
manually changed as Coccinelle didn't. Further local variables have been
removed as they became unused as a result of the other changes.
Also Coccinelle introduced indentation by space in files
drivers/media/i2c/st-mipid02.c and
drivers/media/platform/rockchip/rkisp1/rkisp1-isp.c. This has been also
corrected.

Add support for C-PHY on R-Car V4H. While the V4H supports both D-PHY
and C-PHY this patch only adds support for the C-PHY mode due to lack of
documentation and hardware to test on.
The V4H is the first Gen4 device that is enabled in the rcar-csi2
driver. There is much overlap with the Gen3 driver, the primary
difference is in how the receiver is started. The V4H have a much larger
register space and some addresses overlap with Gen3.

Set the v4l2_device already in async notifier init, so struct device
related to it will be available before the notifier is registered. This
requires separating notifier initialisation into two functions, one that
takes v4l2_device as its argument, v4l2_async_nf_init and
v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the
notifier will use a single function, v4l2_async_nf_register.
This is done in order to make struct device available earlier, during
construction of the async connections, for sensible debug prints.

This patch re-arranges internal V4L2 async lists for preparation of
supporting multiple connections per sub-device as well as cleaning up used
lists.
The list of unbound V4L2 sub-devices shall be maintained for the purpose of
listing those sub-devices only, not for their bindin status. Also, the V4L2
async connections now have, instead of two list entries, a single list
entry in the notifier's list, be that either waiting or done lists, while
the notifier's asc_list is removed.
The one-to-one relation between a sub-device and a connection is still

Rename v4l2_async_subdev as v4l2_async_connection, in order to
differentiate between the sub-devices and their connections: one
sub-device can have many connections but the V4L2 async framework has so
far allowed just a single one. Connections in this context will later
translate into either MC ancillary or data links.
This patch prepares changing that relation by changing existing users of
v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices
themselves will not be needed anymore
Additionally, __v4l2_async_nf_add_subdev() has been renamed
__v4l2_async_nf_add_connection().

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

When adding proper support for V4L2_FIELD_ALTERNATE it was missed that
this field format should trigger an interrupt for each field, not just
for the whole frame. Fix this by marking it as progressive in the
capture setup, which will then select the correct interrupt mode.
Tested on both Gen2 and Gen3 with the result of a doubling of the frame
rate for V4L2_FIELD_ALTERNATE. From a PAL video source the frame rate is
now 50, which is expected for alternate field capture.

returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

The V4L2 subdevs have managed without centralized locking for the state
(previously pad_config), as the try-state is supposedly safe (although I
believe two TRY ioctls for the same fd would race), and the
active-state, and its locking, is managed by the drivers internally.
We now have active-state in a centralized position, and need locking.
Strictly speaking the locking is only needed for new drivers that use
the new state, as the current drivers continue behaving as they used to.
However, active-state locking is complicated by the fact that currently
the real active-state of a subdev is split into multiple parts: the new
v4l2_subdev_state, subdev control state, and subdev's internal state.
In the future all these three states should be combined into one state
(the v4l2_subdev_state), and then a single lock for the state should be
sufficient.
But to solve the current split-state situation we need to share locks
between the three states. This is accomplished by using the same lock
management as the control handler does: we use a pointer to a mutex,
allowing the driver to override the default mutex. Thus the driver can
do e.g.:
sd->state_lock = sd->ctrl_handler->lock;
before calling v4l2_subdev_init_finalize(), resulting in sharing the
same lock between the states and the controls.
The locking model for active-state is such that any subdev op that gets
the state as a parameter expects the state to be already locked by the
caller, and expects the caller to release the lock.

being.
Prefix the functions with __ to mark the functions as internal.
At the same time, rename them to v4l2_subdev_state_alloc and
