Hello
  this small series introduces OF support for the ov5670 sensor and
adds support for regulators clocks and GPIOs.

Last year I dropped the ball as I didn't have access to HW anymore.
Luca (in cc) has reported he has a sensor and might give this new version
a spin, thanks!

Cheers

v4->v5:
- Enable clock in ov5670_runtime_resume() as suggested by Luca
- Add a patch to handle HBLANK, PIXEL_RATE and LINK_FREQ in .set_ctrl()
  to fix a warning again reported by Luca

v3->v4:
- Rework power enablement in power up sequence to support !CONFIG_OF
- Minor changes as per Sakari's review

v2->v3:
- bindings:
  - Drop assigned-clock properties from schema (moved to example)
  - s/pwdn-gpios/powerdown-gpios/

- driver
  - Use is_of_node() to decide how to parse clocks
  - Fix:
    drivers/media/i2c/ov5670.c:1787:18: error: initializer element is not a compile-time constant
                   .analog_crop = ov5670_analog_crop,
                                  ^~~~~~~~~~~~~~~~~~

    reported by kernel test robot and Nathan Chancellor with
    clang15 and gcc < 8

v1->v2:
- Address Krzysztof comments on bindings
- 2/8: new patch to use the common clock framework
- Address Lauren's comment on runtime_pm function names
- 7/8: new patch to implement init_cfg as suggested by Laurent
- Rework 8/8 which was incorrect as reported by Laurent

Thanks
