This series adds platform support for the V3s/V3/S3 MIPI CSI-2 and ISP units
as well the as A83T MIPI CSI-2 unit in the respective device-trees.
Overlays for the BananaPi M3 cameras are also provided as actual users of the
camera pipeline on A83T.

The corresponding drivers and dt bindings were merged a long time ago but this
series was never actually picked up. It seems more than ready to be merged!

Changes since v8:
- Added collected review tags;
- Added the overlays to be built as full dtbs.
- Removed trailing whitespace.

Changes since v7:
- Added collected review tags;
- Added interconnect properties to bindings;
- Added compatible for device-tree overlays;
- Moved mclk pin to sensor node in bpi-m3 overlays;
- Removed duplicated assigned-clocks in bpi-m3 overlays.

Changes since v6:
- Rebased on top of the latest media tree, renamed dts to dtso for overlays.

Changes since v5:
- Added BananaPi M3 camera sensor support as device-tree overlays;
- Cleaned-up OV8865 regulator definitions;
- Always declared the internal links between CSI and MIPI CSI-2 on A83T
  in device-tree.

Changes since v4:
- Removed mbus bindings patch: an equivalent change was merged;
- Added collected tags;
- Rebased on latest media tree.

Changes since v3:
- Reordered v3s mbus compatible in binding;
- Added collected tag;
- Removed rejected interconnects fix.

Changes since all-in-one v2:
- Corrected mbus index used for the interconnects;
- Used extended mbus binding and exported the DRAM clock for that;
- Reworked the description of the core openfirmware change to give
  more insight about the situation.
