[PATCH v4 0/3] media: i2c: OV8865 image sensor support

[Paul Kocialkowski <paul.kocialkowski@bootlin.com>]

This series adds support for the OV8865 image sensor, as a V4L2 subdev
driver. Although an initial series was submitted by Kévin L'hôpital some
weeks ago, this version is significantly new and should be considered a
new series.

The final patch (not for merge) shows how to enable the OV8865 on the
Banana Pi Camera Board v2 with the Banana Pi M3.

Changes since v3:
- Removed debug read in write helper;
- Squashed tailing function calls in return;
- Added Kconfig depend on PM since it's not optional;
- Reordered runtime PM in init;
- Reworked runtime PM order and added ctrls handler free in exit.

Changes since v2:
- Added link-frequencies endpoint property support;
- Marked avdd-supply as non-optional (no internal regulator);
- Used NULL ctrl ops for pixel rate and link freq;
- Extra cosmetic changes.

Changes since v1:
- Used runtime pm;
- Used assigned-clock-rate;
- Removed clock name;
- Returned closest size in set_fmt;
- Removed unneeded references to v4l2 controls;
- Removed unneeded structure packing attribute;
- Removed i2c device table;
- Dual-licensed bindings;
- Used SPDX tags.
