Commit 1dc01bc9e6c3 ("ipa: libipa: histogram: Add transform parameter to

implementation is inline in the header file, and the documentation was
added in the corresponding .cpp file, but it missed the \fn directive.
This causes Doxygen to complain:

Add a parameter to the histogram constructor that takes a transformation
function to apply to all the bins upon construction.
This is necessary notably for the rkisp1, as the values reported from
the hardware are 20 bits where the upper 16-bits are meaningful integer
values and the lower 4 bits are fractional and meant to be discarded. As
adding a right-shift parameter is probably too specialized, a generic
function is added as a parameter instead.
While at it, optimize the existing constructor to avoid push_back() into
a vector with a known final size.

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']='# '
['sh']='# '
)
for ext in ${!patterns[@]} ; do
files=$(for dir in $dirs ; do find $dir -name "*.${ext}" ; done)
pattern=${patterns[${ext}]}
for file in $files ; do
name=$(basename ${file})
sed -i "s/^\(${pattern}\)${name} - /\1/" "$file"
done
done
----------------------------------------
This misses several files that are out of sync with the comment block
header. Those will be addressed separately and manually.

Support for the OmniVision OV8858 sensor is scheduled for inclusion in
the Linux kernel in version v6.3.
Add support for the sensor in libcamera by providing static properties
and a camera sensor helper in libipa.
The camera sensor helper expresses analogue gain increments in 1/128
step which differs from what is reported in the sensor documentation in
section "5.8 manual exposure compensation/ manual gain compensation" [0]
A more detailed analysis of the sensor gain model is reported at:
https://patchwork.linuxtv.org/project/linux-media/patch/20221106171129.166892-2-nicholas@rothemail.net/#142267

The sensor analogue gain is implemented as a coarse and a fine factor,
with the coarse gain being a power of two and the fine gain being a
value in the [1.0, 2.0[ range. The mapping between gain codes and gain
values is tabulated in the datasheet, and the table values are very
close but not identical to the mathematical model. Compute the gain
using the model to keep the code shorter, if this causes precision
issues the calculation could be replaced with a table.
