Message

Hi,

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.

Changes since v1:
- Deleted starfive,jh7110-mipi-csi2.yaml.
- Converted cdns,csi2rx.txt to cdns,csi2rx.yaml and added ‘resets’
  properties.
- Added ‘cdns,csi2rx.yaml’ in ‘CADENCE MIPI-CSI2 BRIDGES’ entry.
- The following contents were modified in starfive,jh7110-camss.yaml:
  dropped quotes from ’id’ and ‘schema’; dropped ‘|’ for ‘description’;
  corrected the wrong or redundant words: ‘a ISP’, ‘PD ISP’;
  dropped ‘minItems’ for ‘reg’, ‘clocks’, ‘resets’ and ‘interrupts’;
  dropped the '_clk' and 'rst_' prefix about the 'clock-names' and
  'reset-names';
  changed ‘endpoint@1’ to ‘endpoint’; updated examples;
- Updated Subject for some patches.
- Merged patch 6, 7, 8, 9, 10, 11 into one patch.
