However, it does make sense to make things as similar as possible to White Hawk (Single). In the end, I do hope to share most of the White/Gray Hawk (Single) DTS. Of course we have to cater for the small differences like the use of a C-PHY vs. D-PHY, which is one difference I hadn't realized before. What do other people think?

Before adding the CSI nodes for gray-hawk create a dedicated DTS file for the CSI/DSI functionality to reflect what is done for white-hawk. For now its contents are limited to the Board ID EEPROM.
