I still need support. The patch did not work. Please see patch below.
I still can only get 2 cameras continuously streaming.

I also noticed, I potentially did the wrong thing in the device tree. Based on:

	/**
		 * The general guideline for naming badge_info contains 3 parts, and is as follows,
		 * The first part is the camera_board_id for the module; if the module is in a FFD
		 * platform, then use the platform name for this part.
		 * The second part contains the position of the module, ex. "rear" or "front".
		 * The third part contains the last 6 characters of a part number which is found
		 * in the module's specsheet from the vendor.

-badge = "porg_*_AR0231AT";
+badge = "porg_*_AR0231";

However, this made no difference to the streaming issue.
