Subject: [PATCH v6 0/7] Allwinner A31/A83T MIPI CSI-2 and A31 ISP / Platform Support

This part only concerns Allwinner platform support changes.

Though some patches still need reviewing, they feel ready to go since the
MIPI CSI-2 bindings were merged, the updated CSI bindings were reviewed by
Rob and the new ISP bindings as well. Although they were not merged yet,
they seem ready to go at this point.

Since this multi-part series has been going on for a while, it would be
great to see it merged soon!

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
