34bee5e84e libcamera: V4L2Device: Remove the controls order assumption in updateControls()
The original updateControls() has the assumption that ctrls and
v4l2Ctrls lists are in the same order. It is dependent on the
caller implementation though. This changes updateControls()
implementation so that it works without the assumption.

c76ca01323 ipa: ipu3: Introduce IPAConfigInfo in IPC
IPAConfigInfo is a consolidated data structure passed from IPU3
pipeline-handler to IPU3 IPA. The structure can be extended with
additional parameters to accommodate the requirements of multiple
IPU3 IPA modules.

Adapt the in-tree IPU3 IPA to use IPAConfigInfo as well.

6449590b63 ipa: mojom: Move CameraSensorInfo struct exclusively to IPA IPC
CameraSensorInfo structure is designed to pass in camera sensor related
information from pipeline-handler to IPA. Since the pipeline-handler
and IPA are connected via mojom IPC IPA interface, the interface
itself provides a more suitable placement of CameraSensorInfo,
instead of camera_sensor.h (which is a libcamera internal header
ultimately, at this point).

As CameraSensorInfo is already defined in core.mojom, it is just
a matter of removing [skipHeader] tag to allow code-generation
of CameraSensorInfo.

Finally, update header paths to include CameraSensorInfo definition
from IPA interfaces instead of "libcamera/internal/camera_sensor.h".

ff9276cc62 ipa: Move core IPA interface documentation to a .cpp file
Moving the core.mojom documentation to its corresponding .cpp file
(core_ipa_interface.cpp). This will allow Doxygen to generate the
documentation for IPABuffer, IPASettings and IPAStream structures.
Since the .mojom files are placed in include/ directory, the .cpp file
will live in $sourcedir/src/libcamera/ipa/ - which can also contain
documentation for other mojom generated IPA interfaces in subsequent
commit.

Also hide the constructors in generated IPA interface from doxygen,
via  #ifndef __DOXYGEN__. These constructors provide no major value in
documenting them, instead will spew out doxygen warnings during the
build.

630c83f82a libcamera: ipu3: imgu: Fix BDS height calculation
The IF rectangle height is iteratively computed by first subtracting
the scaling factor to the estimated height, then in a successive loop
by adding the same scaling factor until the maximum IF size is not
reached.

As the computed IF height is not cached in any variable, the second
loop over-writes the result of the first one, even if the BDS alignment
condition is not satisfied.

Fix this by caching the result of the two iterations, and use the one
that produced any result, with a preference for the one produced by the
second loop, as implemented in the reference python script.

ad38d9151b libcamera: utils: Add enumerate view for range-based for loops
Range-based for loops are handy and widely preferred in C++, but are
limited in their ability to replace for loops that require access to a
loop counter.  The enumerate() function solves this problem by wrapping
the iterable in an adapter that, when used as a range-expression, will
provide iterators whose value_type is a pair of index and value
reference.

The iterable must support std::begin() and std::end(). This includes all
containers provided by the standard C++ library, as well as C-style
arrays.

A typical usage pattern would use structured binding to store the index
and value in two separate variables:

std::vector<int> values = ...;

for (auto [index, value] : utils::enumerate(values)) {
     ...
}

However, not all pipeline handlers invoke the setFormat method

99de822436 libcamera: buffer: Re-work setRequest() documentation
I got fooled by the documentation of setRequest() implying that the
function is meant to be called by pipeline handlers only, which it is
used in the Request class at Request::addBuffer() and Request::reuse()
time.

Rework the documentation to report that.

787c90027c libcamera: vimc: Report sensor timestamp
Report the sensor's timestamp in the Request metadata using the
completed buffer timestamp.

The buffer's timestamp reports the video capture buffer processing time,
and it does not theoretically matches the 'start of exposure'
definition.

VIMC being a testing platform and the test driver completes the buffers
for each media entity connected in the pipeline one after the other, the
current solution is acceptable for the pipeline.

210c59b6bb libcamera: rkisp1: Do not over-write metadata
When a Request is completed upon receiving the IPA produced metadata,
the metadata associated with the Request are over-written, deleting
the information set at output buffer completion, such as the
SensorTimestamp.

This commit applies to the RkISP1 pipeline handler the same change
applied to IPU3 in commit 2ee3dd57e2fc ("libcamera: ipu3: Merge IPA
metadata controls").

cb43c18040 libcamera: ipu3: Report sensor timestamp
Report the sensor's timestamp in the Request metadata by using the
CIO2 buffer timestamp as an initial approximation.

The buffer's timestamp is recorded at DMA-transfer time, and it does not
theoretically matches the 'start of exposure' definition, but when used
to compare two consecutive frames it gives an acceptable estimation of
the sensor frame period duration.
