[libcamera-devel] [PATCH 6/7] [DNI] utils: tuning: Add full libtuning raspberrypi tuning script

[Paul Elder]

Add a tuning script for raspberrypi that uses libtuning. This reproduces
what ctt does (albeit with less logging for now), but with common
components factored out into libtuning so that tuning scripts for other
platforms can reuse them.

This is incomplete, hence the DNI.
