We have 'struct v4l2_subdev_pad_config' which contains configuration for
a single pad used for the TRY functionality, and an array of those
structs is passed to various v4l2_subdev_pad_ops.
I was working on subdev internal routing between pads, and realized that
there's no way to add TRY functionality for routes, which is not pad
specific configuration. Adding a separate struct for try-route config
wouldn't work either, as e.g. set-fmt needs to know the try-route
configuration to propagate the settings.
This patch adds a new struct, 'struct v4l2_subdev_state' (which at the
moment only contains the v4l2_subdev_pad_config array) and the new
struct is used in most of the places where v4l2_subdev_pad_config was
used. All v4l2_subdev_pad_ops functions taking v4l2_subdev_pad_config
are changed to instead take v4l2_subdev_state.
The changes to drivers/media/v4l2-core/v4l2-subdev.c and
include/media/v4l2-subdev.h were written by hand, and all the driver
changes were done with the semantic patch below. The spatch needs to be
applied to a select list of directories. I used the following shell
commands to apply the spatch:
dirs="drivers/media/i2c drivers/media/platform drivers/media/usb drivers/media/test-drivers/vimc drivers/media/pci drivers/staging/media"
for dir in $dirs; do spatch -j8 --dir --include-headers --no-show-diff --in-place --sp-file v4l2-subdev-state.cocci $dir; done
Note that Coccinelle chokes on a few drivers (gcc extensions?). With
minor changes we can make Coccinelle run fine, and these changes can be
reverted after spatch. The diff for these changes is:

The 'from' variable at preview_config() expects an __user * type.
However, the logic there does:
from = *(void * __user *) ((void *)cfg + attr->config_offset);
With actually means a void pointer, pointing to a void __ user
pointer. When the first pointer is de-referenced with *(foo),
the type it returns is "void *" instead of "void __user *".
Change it to:
from = *(void __user **) ((void *)cfg + attr->config_offset);
in order to obtain, when de-referenced, a void __user pointer,
as desired.
That prevent those warnings:

The sequence number counter is incremented on each output buffer, and that
incremented value is used as the sequence number of that buffer. The input
buffer sequence numbering is based just on reading the same counter. If
the input buffer is marked done first, its sequence number ends up being
that of the output buffer - 1.
This is how the resizer works as well.

The entities to video nodes links were created on separate functions for
each ISP module but since the only thing that these functions do is to
call media_create_pad_link(), there's no need for that indirection level
and all link creation logic can be just inlined in the caller function.
Also, since the only possible failure for the link creation is a memory
allocation, there is no need for error messages since the core already
reports a very verbose message in that case.

With the MC next gen rework, what's left for media_entity_init()
is to just initialize the PADs. However, certain devices, like
a FLASH led/light doesn't have any input or output PAD.
So, there's no reason why calling media_entity_init() would be
mandatory. Also, despite its name, what this function actually
does is to initialize the PADs data. So, rename it to
media_entity_pads_init() in order to reflect that.
The media entity actual init happens during entity register,
at media_device_register_entity(). We should move init of
num_links and num_backlinks to it.

On omap3/omap4/davinci drivers, MEDIA_ENT_T_V4L2_SUBDEV macro is
abused in order to "simplify" the pad checks.
Basically, it does a logical or of this macro, in order to check
for a local index and if the entity is either a subdev or not.
As we'll get rid of MEDIA_ENT_T_V4L2_SUBDEV macro, replace it by
2 << 16 where it occurs, and add a note saying that the code
there is actually a hack.

The omap3isp driver initializes the entities and creates the pads links
before the entities are registered with the media device. This does not
work now that object IDs are used to create links so the media_device
has to be set.
Split out the pads links creation from the entity initialization so the links
are created after the entities have been registered with the media device.

With the new API, a link can be either between two PADs or between an interface
and an entity. So, we need to use a better name for the function that create
links between two pads.
So, rename the such function to media_create_pad_link().
No functional changes.

Currently, media_entity_init() creates an array with the links,
allocated at init time. It provides a parameter (extra_links)
that would allocate more links than the current needs, but this
is not used by any driver.
As we want to be able to do dynamic link allocation/removal,
we'll need to change the implementation of the links. So,
before doing that, let's first remove that extra unused
parameter, in order to cleanup the interface first.

If a subdevice pad op is called from a bridge driver, then there is
no v4l2_subdev_fh struct that can be passed to the subdevice. This
made it hard to use such subdevs from a bridge driver.
This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config
pointer in the pad ops. This allows bridge drivers to use the various
try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it
along to the pad op.
The v4l2_subdev_get_try_* macros had to be changed because of this, so
I also took the opportunity to use the full name of the v4l2_subdev_get_try_*
functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do
'git grep v4l2_subdev_get_try_format' you will actually find the header
where it is defined.
One remark regarding the drivers/staging/media/davinci_vpfe patches: the
*_init_formats() functions assumed that fh could be NULL. However, that's
not true for this driver, it's always set. This is almost certainly a copy
and paste from the omap3isp driver. I've updated the code to reflect the
fact that fh is never NULL.

The preview engine includes filters that consume columns and lines as
part of their operation, thus resulting in a cropped image. To allow
turning those filters on/off during streaming without affecting the
output image size, the driver adds additional cropping to make the total
number of cropped columns and lines constant regardless of which filters
are enabled.
This process needlessly includes the CFA filter, as whether the filter
is enabled only depends on the sink pad format, which can't change
during streaming.
Exclude the CFA filter from the preview engine margins.
