When the colour temperature does not change between frames, the ccm
inside the frame context is not updated and the metadata contains
invalid data. Fix that by caching the ccm inside the active state.

The frame context is used to store data used for processing that frame.
It is later used to either act as input for other algorithms or to fill
the metadata. For the colour temperature this is not needed, as the
meatadata shall not contain the value that was active when the image was
processed, but the value that was calculated based on the statistics for
that image. This is no functional change.

When the color gains are set manually it is possible to specify a
gain that wrapped the hardware limits. It would also be possible to
further tune the floating point limits, but that is an error prone
approach. So the limits are imposed on the integers, just before writing
to the hardware. This noticeably reduces some oscillations in the awb
regulation.

Add sensor black levels to the metadata of the rkisp1 pipeline.
Additionally enable raw support for this algorithm and add it to
uncalibrated.yaml, so that black levels get reported when capturing
tuning images. This is a bit of a hack, because no actual black level
correction is taking place in raw mode, but it is the easiest way to get

As the camera sensor helper now has the ability to provide the black
level, use it. Black levels can still be overwritten by the tuning
file, but the direction is to remove them from the tuning files and move
them into the sensor helpers.
Additionally interpret all values based on 16bits. The conversion to the
scale required by the hardware is done in process(). It ensures all the
values inside libcamera are the same scale and is in preparation for the
i.MX8MP where black levels are based on a 20bit scale. Note that this
breaks existing tuning files. The tuning files distributed with
libcamera will be fixed in a later patch.

that models the gamma curve is so coarse that there is basically no difference

Source files in libcamera start by a comment block header, which
includes the file name and a one-line description of the file contents.
While the latter is useful to get a quick overview of the file contents
at a glance, the former is mostly a source of inconvenience. The name in
the comments can easily get out of sync with the file name when files
are renamed, and copy & paste during development have often lead to
incorrect names being used to start with.
Readers of the source code are expected to know which file they're
looking it. Drop the file name from the header comment block.
The change was generated with the following script:
----------------------------------------
dirs="include/libcamera src test utils"
declare -rA patterns=(
['c']=' \* '
['cpp']=' \* '
['h']=' \* '
['py']='# '

)
for ext in ${!patterns[@]} ; do

pattern=${patterns[${ext}]}
for file in $files ; do
name=$(basename ${file})
sed -i "s/^\(${pattern}\)${name} - /\1/" "$file"
done

----------------------------------------
This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

Versions of the ISP differ in the processing blocks they include, as
well as in the implementation of some of those blocks. In particular,
they have different numbers of histogram bins oe AE statistics cells.
The algorithms take these differences into account by checking the ISP

These checks are currently scattered in multiple places. Centralize them
in the IPARkISP1::init() function, and store the version-dependent
hardware parameters in the IPA context, accessible by all algorithms.

The RkISP1 can capture raw frames by bypassing the ISP. In that mode,
the ISP will not produce statistics nor consume parameters. Most
algorithms will thus be unable to run, with one exception: the AGC will
still be able to configure the sensor exposure time and analog gain in
manual mode.
To prepare for this, add the ability to disable algorithms for the
duration of the capture session based on the camera configuration.
Individual algorithms report whether they support raw formats at
construction time, and the IPA module disables algorithms in configure()
based on the stream configurations.
Disabled algorithms are skipped during the capture session in the
processStatsBuffer() operation. As the ISP doesn't produce statistics,
don't try to access the stats buffer. There is no need for similar logic
in fillParamsBuffer() as that operation won't be called for raw capture.
All algorithms report not supporting raw capture by default. Raw support
in AGC will be added separately.
The feature is implemented in the RkISP1 module without any support from
libipa at this point to avoid designing a generic API based on a single
user. This may be changed in the future.
