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
