[v2,00/13] 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 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.

Don't we need to do something like

	media_entity_remove_links(&cap_yuv->video.vdev.entity);

as part of the cleanup?  Also where do we clean up this new call to
media_create_pad_link() in the unregister process?

Hi Laurent,

Could you please help to review and give your comments? 
Thanks a lot!
