Subject: [PATCH v6 0/6] Allwinner A31/A83T MIPI CSI-2 and A31 ISP / ISP Driver

This part only concerns the introduction of the new ISP driver and related
adaptation of the CSI driver.

Most non-dt patches still need reviewing but should be pretty straightforward. 
Since this multi-part series has been going on for a while, it would be great
to see it merged soon!

Changes since v5:
- Rebased on latest media tree;
- Added collected tag;
- Switched to using media_pad_remote_pad_first;
- Switched to using media_pad_remote_pad_unique.

Changes since v4:
- Fixed device-tree binding indent-align;
- Added collected tag;
- Rebased on latest media tree;

Changes since v3:
- Removed the v4l2 controls handler from the driver;
- Added variant structure for table sizes;
- Removed the info message about video device registration;
- Removed comments in uAPI header;
- Used '/schemas/graph.yaml#/properties/port' whenever possible in bindings;
- Added CSI patches dependent on the ISP driver;
- Rebased on the latest media tree;

Changes since all-in-one v2:
- Updated Kconfig to follow the latest media-wide changes;
- Reworked async subdev handling with a dedicated structure holding the
  corresponding source to avoid matching in the driver;
- Switched to clock-managed regmap mmio;
- Used helper to get a single enabled link for an entity's pad, to replace
  source selection at link_validate time and select the remote source at
  stream on time instead;
- Added mutex for mbus format serialization;
- Used endpoint-base instead of video-interface for "internal" endpoints
  in device-tree schema;
- Added TODO with unstaging requirements;
- Various cosmetic cleanups;
- Updated copyright years;
