[PATCH 0/5] Software ISP levels cleanup

[Milan Zamazal]

This is a cleanup of black level and color gain handling in software ISP.
It fixes omission of black level subtraction in white balance computation and moves color lookup tables computations out of debayering.  The latter also serves as a preparation for bringing software ISP algorithms closer to common libcamera algorithm handling, in future patches.

Milan Zamazal (5):
  libcamera: software_isp: Use a specific integer type for black level
  libcamera: software_isp: Honor black level in AWB
  libcamera: software_isp: Move color mappings out of debayering
  libcamera: software_isp: Remove TODO #13
  libcamera: software_isp: Remove DebayerParams::kGain10
