Subject: [PATCH v7 0/7] Allwinner A31/A83T MIPI CSI-2 and A31 ISP / Platform Support

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 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.

Paul Kocialkowski (7):
  clk: sunxi-ng: v3s: Export MBUS and DRAM clocks to the public header
  ARM: dts: sun8i: v3s: Add mbus node to represent the interconnect
  ARM: dts: sun8i: v3s: Add nodes for MIPI CSI-2 support
  ARM: dts: sun8i: v3s: Add support for the ISP
  ARM: dts: sun8i: a83t: Add MIPI CSI-2 controller node
  ARM: dts: sun8i-a83t: Add BananaPi M3 OV5640 camera overlay
  ARM: dts: sun8i-a83t: Add BananaPi M3 OV8865 camera overlay
