Hi, This series is the v10 series that attempts to support the Camera Subsystem found on StarFive JH7110 SoC. 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). The following are the media graph for the device and the v4l2-compliance output. =========================================================================== [the media graph]: digraph board {

Failed: 0, Warnings: 0 =========================================================================== Changes in v10: - Tested the driver with a v4l2-compliance compiled from the git repo (git://linuxtv.org/v4l-utils.git). - Rebased on top of the master branch of media_stage repository. v9 link: https://lore.kernel.org/all/20230914031607.34877-1-jack.zhu@xxxxxxxxxxxxxxxx/ Changes in v9: - Rebased on top of the master branch of media_stage repository. - Renamed file name. - Added of_node_put(node) in the error handling path of stfcamss_of_parse_ports(). v8 link: https://lore.kernel.org/all/20230824080109.89613-1-jack.zhu@xxxxxxxxxxxxxxxx/ Changes in v8: - Rebased on v6.5-rc7. - Dropped VIN subdev. - Created two new video devices: capture_raw and capture_yuv, to replace the previous video devices. - Dropped VB2_READ io methods. - Recursively called .s_stream() on subdevs. v7 link: https://lore.kernel.org/all/20230619112838.19797-1-jack.zhu@xxxxxxxxxxxxxxxx/ Changes in v7: - HAS_DMA is used instead of DMA_CMA in Kconfig. - Dropped some non-essential member variables. - Used v4l2_async_nf_add_fwnode_remote() to simplify the relevant code. - Modified some Local variable types in the function. - Used v4l2_create_fwnode_links_to_pad() to simplify the relevant code. - Added error handling for clk_prepare_enable(). - Simplified stfcamss_format_info struct and modified the relevant code. - Dropped enum_input, g_input and s_input. - Unified v4l2_ioctl_ops struct. - Used v4l2_fh_open()/vb2_fop_release to replace deprecated APIs. - Added a camss directory under the starfive directory and modified the patch title. v6 link: https://lore.kernel.org/all/20230525083202.67933-1-jack.zhu@xxxxxxxxxxxxxxxx/ Changes in v6: - Added 'bus-type' in bindings example. - Corrected spelling errors. - As reviewed by Bryan, used 'nclks' and 'nrsts' variables. - Added lccf config for ISP. v5 link: https://lore.kernel.org/all/20230512102844.51084-1-jack.zhu@xxxxxxxxxxxxxxxx/ Changes in v5: - Rebased on v6.4-rc1. - Added new patch. - Modified ISP driver. v4 link: https://lore.kernel.org/all/20230413035541.62129-1-jack.zhu@xxxxxxxxxxxxxxxx/ Previous cover letter from v4: This patch series adds support for the StarFive Camera Subsystem found on StarFive JH7110 SoC. The driver implements V4L2, Media controller and V4L2 subdev interfaces. Camera sensor using V4L2 subdev interface in the kernel is supported. The driver is tested on VisionFive V2 board with IMX219 camera sensor. GStreamer 1.18.5 with v4l2src plugin is supported.
