[PATCH v3 00/23] Add ccm calibration to libtuning

[Stefan Klug]

Hi all,

this patch series improves the rkisp1 tuning tool support. With that
code, it is possible to create a nice looking image on the imx8mp. It
incorporates some logic from the raspberrypi tuning tools. This was used
to get to a working state in a timely manner. After that further
refactoring and algorithm development can take place.

Feature wise it contains:
- Added ccm calibration for the rkisp1
- Add static support for awb, filter, gamma and cproc
- Fixed lsc correction tables
- Some general fixes to make all that work

Best regards,
Stefan

Changes in v3:
- Replaced BLC module by a simple static module as the black level is now 
  provided by the camera sensor helpers (seperate series).
- Dropped P23 ([PATCH v2 23/25] libtuning: Make blacklevel optional).
- Collected tags.
- Fixed typos and comments from first review.
- P12 is now split in two.
