Paul Kocialkowski Feb. 5, 2022, 6:53 p.m. UTC 
This series introduces support for the Allwinner A31 and A83T MIPI CSI-2
controllers as well as the Allwinner A31 Image Signal Processor (ISP).
It follows v5 of the "Allwinner MIPI CSI-2 support for A31/V3s/A83T"
series, with the addition of ISP support for the V3. Since both aspect
are quite dependent due to changes to the sun6i-csi driver, they are
merged into this new series.

Aside from the ISP driver itself, the most outstanding change is a
significant rework of the CSI driver, to bring it to a state that
makes it possible to integrate with the ISP workflow.
A number of other improvments are also added along the way.

The commit message introducing the ISP driver should also contain useful
details regarding the implementation and outstanding specifics of the hardware.

This was tested on the V3s and A83T, using the IMX219, OV5648, OV8856
and OV8865 sensors.

v4l2-compliance seems pretty happy about the video nodes, see the detailed
reports below.

Thanks!

-- Changelog

Changes since v1:
- Split changes to the sun6i-csi driver into specific patches;
- Added myself as maintainer of the reworked driver;
- Defined and used mbus interconnect as requested, although the approach
  appears to be broken currently (see final commit);
- Removed the patches dealing with PLL clock parenting issues,
  since they are a bit out of scope;
- Fixed various minor issues caught in code review;
- Fixed an undefined return issue;
- Reset capture sequence to 0 at stream start;
- Kept runtime pm only in the bridge/proc paths;
- Followed v4l2 API changes (notifier -> nf);
- A few misc cosmetic changes;
  
-- Previous MIPI CSI-2 series changelog

Changes since v5:
- D-PHY direction is no longer represented with a submode since this is
  not a runtime decision: no switching between the two submodes is
  possible and each instance of a controller will be dedicated to one
  direction only. Instead, a device-tree property is used.
  A separate compatible was considered, but it feels unfit since the
  direction does not describe the particular type of hardware
  implementation, but rather how it is used;
- Updated comments about channels based on latest information;
- Various cosmetic changes (and splitting) to the code;

-- Allwinner MIPI CSI-2 support for A31/V3s/A83T changelog

Changes since v4:
- Added patch to stop using v4l2_async_notifier_parse_fwnode_endpoints;
- Fixed checkpatch strict issues (parenthesis alignment);
- Fixed runtime PM call order and disable;
- Fixed fwnode_handle_put order;
- Brought back phy-names for A31 since it's mandatory according to the generic
  PHY binding and needed by the code;
- Added collected tags.

Changes since v3:
- Fixed single-item phys description in sun6i mipi csi-2 binding;
- Fixed variables names in macros using container_of;
- Fixed style issue with operators at the end of lines;
- Reworked source endpoint/subdev assignment in sun6i-csi to handle
  link_validate error case;
- Removed unrelated dt change in sun8i-a83t mipi csi-2 driver;
- Added collected tags.

Changes since v2:
- added Kconfig depend on PM since it's not optional;
- removed phy-names for A31 MIPI CSI-2 controller;
- removed v3s compatible in the A31 MIPI CSI-2 controller driver;
- removed A31 CSI controller single-port binding deprecation;
- removed empty dt port definitions;
- fixed minor checkpatch warnings;
- added collected tags;
- added media-ctl output in cover letter.

Changes since v1:
- reworked fwnode and media graph on the CSI controller end to have one port
  per interface, which solves the bus type representation issue;
- removed unused IRQ handlers in the MIPI CSI-2 bridges;
- avoided the use of devm_regmap_init_mmio_clk;
- deasserted reset before enabling clocks;
- fixed reported return code issues (ret |=, missing checks);
- applied requested cosmetic changes (backward goto, etc);
- switched over to runtime PM for the mipi csi-2 bridge drivers;
- selected PHY_SUN6I_MIPI_DPHY in Kconfig for sun6i-mipi-csi2;
- registered nodes with mipi csi-2 bridge subdevs;
- used V4L2 format info instead of switch/case for sun6i-csi bpp;
- fixed device-tree bindings as requested (useless properties, license);
- fixed mipi bridge dt instances names;
- added PHY API documentation about mode/power on order requirement;
- fixed clock error return code in d-phy code;
- fixed D-PHY mode check in d-phy code;
- added MAINTAINERS entries for the new drivers;
- added V4L2 compliance results;
- added various comments and rework commit mesages as requested.
