Add a tuning script for rkisp1 that uses libtuning. Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> --- This won't run as we're missing the necessary parser and generator for yaml, parabolic gradient support, and multiple green support in the ALSC module, hence the DNI. As soon as those are added though, this *should* work. --- utils/tuning/rkisp1.py | 69 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 69 insertions(+) create mode 100644 utils/tuning/rkisp1.py
