Subject: [PATCH v5 0/6] Allwinner A31/A83T MIPI CSI-2 and A31 ISP / ISP Driver

This new version is an offspring from the big "Allwinner A31/A83T
MIPI CSI-2 Support and A31 ISP Support" series, which was split into
individual series for better clarity and handling.

This part only concerns the introduction of the new ISP driver.

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;
