Add support for the Raspberry Pi PiSP Back End memory-2-memory ISP. Documentation available at: https://datasheets.raspberrypi.com/camera/raspberry-pi-image-signal-processor-specification.pdf The PiSP Back End is the memory-2-memory ISP found on Raspberry Pi 5. In conjunction with the PiSP Front End, for which a driver is expected to hit mainline in the next weeks, it implements the Raspberry Pi 5 camera system. The ISP is fully supported in the Raspberry Pi libcamera version and once patches for the PiSP Front End will hit mainline the support will land in mainline libcamera as well. Patch based on media-stage master branch.
