This panel is marketed as Banana Pi 7" LCD display. On the back is a sticker denoting the model name S070WV20-CT16.
Judging from the code, the real vendor should be CDTech. Take a look at their website: http://www.cdtech-lcd.com/en/standardscreen.html I point you my patch for inserting another similar panel: https://patchwork.freedesktop.org/patch/211914/ Maybe it would make sense to use CDTech as the vendor, because maybe Bananapi resells only it. Or maybe it is a custom panel done for them, but the same is for other panels I've submitted patches. Micronova srl custom, but vendor is CDTech.

This is a 7" 800x480 panel connected through a 24-bit RGB interface. However the panel only does 262k colors.
