This patchset adds support for changing frame interval and runtime PM for
video-i2c driver. This also adds an helper macro to v4l2 common
internal API that is used to to find a suitable frame interval.
There are a couple of unrelated changes that are included for simplifying
driver initialization code and register accesses.
* v4
- Add Reviewed-by line
- Move set_power() call into release() callback
* v3
- Append result of v4l2-compliance in cover-letter
- Move the code causing use-after-free from video_i2c_remove() to the
video device release() callback.
- Use regmap_init_i2c() instead of devm_regmap_init_i2c() and call
regmap_exit_i2c() in video device release() callback in order to
avoid releasing regmap when the driver is unbound.
- Add Acked-by lines
* v2
- Add Acked-by and Reviewed-by tags
- Update commit log to clarify the use after free
- Add thermistor and termperature register address definisions
- Stop adding v4l2_find_closest_fract() in v4l2 common internal API
- Add V4L2_FRACT_COMPARE() macro in v4l2 common internal API
- Use V4L2_FRACT_COMPARE() to find suitable frame interval instead of
v4l2_find_closest_fract()
- Add comment for register address definisions
