2023-02-09ipa: raspberrypi: Use the generic statistics structure in the algorithmsNaushir Patuck
Repurpose the StatisticsPtr type from being a shared_ptr<bcm2835_isp_stats> to shared_ptr<RPiController::Statistics>. This removes any hardware specific header files and structures from the algorithms source code. Add a new function in the Raspberry Pi IPA to populate the generic statistics structure from the values provided by the hardware in the bcm2835_isp_stats structure. Update the Lux, AWB, AGC, ALSC, Contrast, and Focus algorithms to use the generic statistics structure appropriately in their calculations. Additionally, remove references to any hardware specific headers and defines in these source files.

2023-02-09ipa: raspberrypi: awb: Delay release of the statistics bufferNaushir Patuck
Release the statistics buffer after running the through the AWB calculations. Only the "counted" statistics are copied out to a local structure, so keeping the statistics buffer allows the algorithm to see the "uncounted" statistics as well. This is currently handled by hard-coding the total number of statistics regions regions based on the structure definition in the bcm2835_isp_stats structure.

2023-02-09ipa: raspberrypi: Generalise statisticsNaushir Patuck
At present, the controller algorithms access the bcm2835_isp_stats structure, which is hardware specific. It would be desirable to abstract out the statistics structure to remove hardware specific headers from the algorithms source files. Define a new templated RegionStats class that encompasses region based statistics generated by the ISP. For the VC4 ISP, this can be used to hold RGB sums and focus FoM values. Define a new Statistics structure that holds all the VC4 ISP statistics output. This includes AGC histograms, AGC/AWB region sums and focus FoM regions.

Not all C libraries include support for locale objects (locale_t) and the strto*_l() family of functions. A notable example is uClibc that can be compiled with a hardcoded "C" locale. Compilation then fails as the newlocale(), freelocale() and strtod_l() functions are not defined. Fix the compilation breakage by checking for the availability of the locale_t type, and fall back to strtod() when the type isn't available. This may not lead to the correct result if support for locale objects isn't available and the locale isn't hardcoded to "C", but that is such a corner case that we will likely never encounter it.

2022-12-22ipa: camera_sensor_helper: Add AR0521 supportJacopo Mondi
Add support for OnSemi AR0521 5Mpx image sensor to libipa. 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.
