[PATCH 00/74] RFC: Switch on IFE YUV, Stats and Params support for sm8650

[Bryan O'Donoghue]

This extensive series restructures CAMSS around the idea of lines and
outputs more closely matching the concepts in the camera hardware.

To begin with some bug fixing and some dependencies on the OPE series are
pulled in.

Following that a series of changes to enable the IFE hardware is introduced
for VFE780.

Supported in this drop:

- YUV output on the pix path
  YUV downscale 16 and downscale 4 work on a staging branch
  but with this series at 60 patches I've not included that.

- Stats output
  Bayer histogram only

  How many stats are intended to be brought out this way ?
  Consider that scene in The Terminator when the guy in the gun
  store.

  Gun store owner: "So which will it be"
  The Terminator: "All"

  More seriously once this series lands then it will be possible to bring
  out stats for Agatti mitigating the need for calculating stats in
  software.

- Params application
  AEC Bayer hist params

  Again there are no limits envisaged on which params are to be enabled.

  "All"

- Testing on HDK sm8650

  There is a repo to test this stuff out:
