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@xxxxxxxxxxxxxxxx/ 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@xxxxxxxxxxxxxxxx/ The following are the media graph for the device and the v4l2-compliance output. ========================================================================================== [the media graph]: digraph board { rankdir=TB
