[v5,00/32] media: ov2680: Bugfixes + ACPI + selection(crop-tgt) API support

Hi All,

Unforunately v4 still had an issue with do_div() usage, so here is v5.

This is also available in this branch:
https://git.kernel.org/pub/scm/linux/kernel/git/hansg/linux.git/log/?h=media-ov2680

Changes in v5:
- Add some notes to the ACPI support commit message about the OVTI2680 HID
- Make pixel_rate u64 instead of s64 for do_div() to fix:
  drivers/media/i2c/ov2680.c:1092:2: warning: comparison of distinct pointer types ('typeof ((sensor->pixel_rate)) *' (aka 'long long *') and 'uint64_t *' (aka 'unsigned long long *')) [-Wcompare-distinct-pointer-types]

Changes in v4:
- Rebase on top of latest sailus/media_tree/master (69142f89b61e)
- Do not set v4l2_subdev.fwnode (let v4l2-core do endpoint matching)
- Make enum_frame_interval() input checks more strict
- Make enum_frame_size() returned full-size + binned-/quarter-size
- Use V4L2_CID_ANALOGUE_GAIN for gain
- 3 new patches:
  "media: ov2680: Add bus-cfg / endpoint property verification"
  "media: ipu-bridge: Add link-frequency to OV2680 ipu_supported_sensors[] entry"
  "media: atomisp: Drop atomisp-ov2680 sensor driver"

Changes in v3:
- Add Rui Miguel Silva's Ack for the series
- 2 small fixes for remarks from Andy
- Add a new patch adding me as co-maintainer in MAINTAINERS

Changes in v2
- Drop "media: Add MIPI CCI register access helper functions"
  (being reviewed in its own thread / patch-submission)
- Drop "media: ov2680: Add g_skip_frames op support"
- Add "media: ov2680: Fix regulators being left enabled on
  ov2680_power_on() errors"
- Add "media: ov2680: Add link-freq and pixel-rate controls"
  with this the driver now works on IPU3 with ipu3-capture.sh
  (libcamera support requires adding a couple more controls)
- Limit line length to 80 chars everywhere
- Address various small remarks from Andy

During all the work done on the atomisp driver I have mostly been testing
on devices with an ov2680 sensor. As such I have also done a lot of work
on the atomisp-ov2680.c atomisp specific sensor driver.

With the latest atomisp code from:
https://git.kernel.org/pub/scm/linux/kernel/git/hansg/linux.git/tag/?h=media-atomisp-6.5-1

The atomisp code can now work with standard v4l2 sensor drivers using
the selections (crop-tgt) api and v4l2-async sensor driver registration.

This patch series modifies the main drivers/media/i2c/ov2680.c driver
to add bugfixes, ACPI enumeration, selection API support and further
improvments. After this the driver can be used with the atomisp driver
and atomisp-ov2680.c can be dropped.

This also gets the driver much closer to having everything needed for
use with IPU3 / libcamera. I have a Lenovo Miix 510 now with an IPU3 +
ov2680 sensor and with this series raw-capture using the ipu3-capture.sh
script works. I plan to work on libcamera support for this in the near
future.

Regards,

Hans
