[danieldegrasse]

Introduce driver for ov7670 camera, supporting QCIF,QVGA,CIF, and VGA resolution in YUV and RGB mode.

neat! For the record, could you add in the commit message the board/devkit with wich you tested this.

Sure- it was tested on the FRDM-MCXN947, but that support requires PR #72827, which is dependent on this driver. I can add something like the following to the commit message:

Support was verified on the FRDM-MCXN947, using the SmartDMA camera engine, which is enabled in the following PR: https://github.com/zephyrproject-rtos/zephyr/pull/72827

Would this work?

@loicpoulain could you revisit this PR when you get a chance? I've updated the commit message as requested

[danieldegrasse]

@ngphibang or @josuah, FYI in case either of you would like to provide feedback.

[danieldegrasse]

@decsny would you be willing to review this when you have a chance (or @galak, I'd just like someone to take a look at this from the DTS side based on the assignee the bot selected)

[decsny]

the binding is fairly trivial, reassigning to video area

[ngphibang]

LGTM ! +1

@loicpoulain can you return to this PR for final review
