In media controller mode all VIN instances needs to be part of the same
media graph. There is also a need for each VIN instance to know about
and in some cases be able to communicate with other VIN instances.
Add an allocator framework where the first VIN instance to be probed
creates a shared data structure and registers a media device.
Consecutive VINs insert themself into the global group.

On Gen3 the CSI-2 routing is controlled by the VnCSI_IFMD register. One
feature of this register is that it's only present in the VIN0 and VIN4
instances. The register in VIN0 controls the routing for VIN0-3 and the
register in VIN4 controls routing for VIN4-7.
To be able to control routing from a media device this function is need
to control runtime PM for the subgroup master (VIN0 and VIN4). The
subgroup master must be switched on before the register is manipulated,
once the operation is complete it's safe to switch the master off and
the new routing will still be in effect.

There was never proper support in the VIN driver to deliver ALTERNATING
field format to user-space, remove this field option. The problem is
that ALTERNATING field order requires the sequence numbers of buffers
returned to userspace to reflect if fields were dropped or not,
something which is not possible with the VIN drivers capture logic.
The VIN driver can still capture from a video source which delivers
frames in ALTERNATING field order, but needs to combine them using the
VIN hardware into INTERLACED field order. Before this change if a source
was delivering fields using ALTERNATE the driver would default to
combining them using this hardware feature. Only if the user explicitly
requested ALTERNATE field order would incorrect frames be delivered.
The height should not be cut in half for the format for TOP or BOTTOM
fields settings. This was a mistake and it was made visible by the
scaling refactoring. Correct behavior is that the user should request a
frame size that fits the half height frame reflected in the field
setting. If not the VIN will do its best to scale the top or bottom to
the requested format and cropping and scaling do not work as expected.

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.

currently returns a random value. Instead, return 1.
That's probably better than returning 0, as this is very
likely what happens in practice with the current code, as
as the probably of an unititialized 32 bits integer to
have an specific value (0, in this case), is 1/(2^32).
An alternative would be to return an error code, and
let the caller to hint, based on the past received

Except for some includes (with doesn't seem to be used), this
driver builds fine with COMPILE_TEST.
So, add checks there to avoid building it if ARCH_DAVINCI
is not selected.
Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
The only reason why this driver doesn't build with COMPILE_TEST
is because it includes mach/mux.h. It turns that none of the
macros defined there are used.
So, get rid of it, in order to allow it to build with
COMPILE_TEST.

When a BRx is provided by a pipeline, the WPF must determine the master
layer. Currently the condition to check this identifies pipe->bru ||
pipe->num_inputs > 1.
The code then moves on to dereference pipe->bru, thus the check fails
static analysers on the possibility that pipe->num_inputs could be
greater than 1 without pipe->bru being set.
The reality is that the pipeline must have a BRx to support more than
one input, thus this could never cause a fault - however it also
identifies that the num_inputs > 1 check is redundant.
Remove the redundant check - and always configure the master layer
appropriately when we have a BRx configured in our pipeline.

An older version of the driver patches were merged accidentally which
resulted in missing the array_size parameter that tells the length of the
array that contains the different supported sizes.
Bring it back to v4l2_find_nearest size and make the corresponding change
for the drivers using it as well.
