This patch series adds support for the following to ‘simple’ pipeline
raw output:

- Gathering statistics from the raw images.
- Running softisp IPA on the images (without modifying the images).
- Providing metadata from the IPA.
- Adjusting exposure/gain.

A better approach might be to split ‘simple’ pipeline into specific
pipelines for the functionality currently mixed there: converters,
debayering, raw output.  Modular pipelines composable from independent
pieces might be even better.  But such approaches would require much
more work; this patch series tries to address immediate needs without
complex restructuring of ‘simple’ pipeline.

Milan Zamazal (3):
  libcamera: software_isp: Use shared stats
  libcamera: software_isp: Separate IPA start/stop
  libcamera: software_isp: Allow running IPA and stats on raw
