Subject: [PATCH v10 0/8] Add StarFive Camera Subsystem driver

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.

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.
