[v3,00/13] Add ISP 3A for StarFive

  This series implements the ISP 3A function to the Camera Subsystem on StarFive
JH7110 SoC. The series has been tested on the VisionFive 2 board.

This series is based on top of the master branch of media_stage repository,
which is tested with a v4l2-compliance compiled from the git repo
(git://linuxtv.org/v4l-utils.git).

changes since v2:
- Rebsaed on  top of the master branch of media_stage repository.
- Add helper function "media_entity_remove_links" in PATCH 8 and PATCH 11 to cleanup links.

v2: https://lore.kernel.org/all/20240111084120.16685-1-changhuang.liang@starfivetech.com/

changes since v1:
- Rebsaed on  top of the master branch of media_stage repository.
- Documentated ISP submodule.
- Add new ISP parameters format and document it.
- Add a meta output video device and link to ISP subdev.
- Replaced control with meta output video buffer for write ISP parameters.
- Separate buffer operation which can use for capture and output device.
- Drop ISP frame sync event.

v1: https://lore.kernel.org/all/20231214065027.28564-1-changhuang.liang@starfivetech.com/


The following are the media graph for the device and the v4l2-compliance
output.

I think instead of adding more support on top of the staging driver, the first 
step would be to get the driver out of staging and make it a regular Linux 
driver. After that new HW support should be added.

We asked for the driver to be upstreamed in staging first because it was
mising important features, which this patch series implements (at least
partly, I still need to review the series in more details). I would
prefer merging the necessary features first, and destaging the driver
next, right after.
