2023-03-31ipa: raspberrypi: Generalise the focus reporting codeNaushir Patuck
Use the generalised focus statistics structure to compute the centre window focus FoM value. This avoids needed to hard-code a specific grid size. Remove the focus reporting algorithm as the functionality is duplicated by this bit of IPA code. Remove focus_status.h as it is no longer needed.

2023-03-07ipa: raspberrypi: imx296: Minor tuning updatesDavid Plowman
Some updates to the tuning for the imx296 sensors. For the colour variant: * Minor change to the AWB curve, making things a little less green. * Updated CCMs that reduce colour saturation to a more accurate level. Thanks to Dr. Rolf Henkel for these measurements and calculations. * Sharpening has been toned down quite a lot. * rpi.focus algorithm added so that the focus measure can be accessed. The sharpening and focus changes are applied to the mono version of the sensor too as we expect similar characteristics.

Add support for Raspberry Pi Camera 3 modules (Sony IMX708 camera sensor) to the Raspberry Pi IPA. These modules are available in either normal or wide angle lens, both with IR or no IR cut options, giving a total for 4 variants. Provide IQ tuning files for all four variants.

"NOIR" modules are ones that have had the IR filters removed but are otherwise identical. The same tuning can be used as for the regular version except that the colour calibration supplied to the AWB algorithm no longer works. Instead we need to switch the algorithm to its basic "grey world" method. Users with "NOIR" modules can switch to the matching "xxx_noir.json" tuning file by using the LIBCAMERA_RPI_TUNING_FILE environment variable.

imx290 and imx327 share the same kernel driver (imx290.c) and are therefore both recognised here as "imx290". We add the necessary CamHelper for these sensors, as well as a camera tuning file. The tuning was done with an Innomaker STARVIS IMX327LQR module. These have no IR cut filter so there is no proper colour tuning. However, you should obtain reasonable results for most modules using this sensor. Specific tunings for further modules can always be added subsequently. To use this sensor on the Raspberry Pi platform, please add dtoverlay=imx290,clock-frequency=74250000 into your /boot/config.txt file.
