[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.

Hi, Laurent

> [PATCH 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).
> 

Are there any updates to this series, I am looking forward to your response.

Regards,
Changhuang
