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 v4: - Rebase on top of the master branch of media_stage repository. - Insert a new PATCH 13 - PATCH 1: 1. Fix spelling error: - corsstakl -> crosstalk - balck -> black - magbitude -> magnitude - FALG -> FLAG 2. Exchange of the values of JH7110_ISP_SC_FLAG_AE_AF and JH7110_ISP_SC_FLAG_AWB - PATCH 8: 1. Synchronous spelling error: FALG -> FLAG 2. Add: if (*num_planes) return sizes[0] < sizeof(struct jh7110_isp_sc_buffer) ? -EINVAL : 0; - PATCH 11: 1. Drop read hook. 2. Add: if (*num_planes) return sizes[0] < sizeof(struct jh7110_isp_params_buffer) ? -EINVAL : 0; - PATCH 12: 1. Add: ready_buf->vb.vb2_buf.timestamp = ktime_get_ns(); ready_buf->vb.sequence = output->buffers.sequence++; to fix "v4l2-compliance -s" Failed. v4: https://lore.kernel.org/all/20240402100011.13480-1-changhuang.liang@xxxxxxxxxxxxxxxx/ changes since v3: - Rebased on top of the master branch of media_stage repository and patch [1][2]. - Replaced "stf_get_isp_scd_type" with "stf_isp_get_scd_type" in PATCH 8. v3: https://lore.kernel.org/all/20240205090424.40302-1-changhuang.liang@xxxxxxxxxxxxxxxx/ changes since v2: - Rebased on top of the master branch of media_stage repository. - Added 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: - Rebased on top of the master branch of media_stage repository. - Documentated ISP submodule. - Added new ISP parameters format and document it. - Added a meta output video device and link to ISP subdev. - Replaced control with meta output video buffer for write ISP parameters. - Separated buffer operation which can use for capture and output device. - Droped ISP frame sync event. v1: https://lore.kernel.org/all/20231214065027.28564-1-changhuang.liang@xxxxxxxxxxxxxxxx/ The following are
