Just to clarify: FreeBSD uses, for the most part, the DTB's that the 'vendor' ships, which is quite often the same ones included in Linux. There's some exceptions where the bindings weren't really hardware independent, or where the abstraction model was really Linux specific (for things like the HDMI stack). However, with the advent of overlays, one would think that a vendor could easily include an overlay with the DTB data for the devices they don't wish to, or cannot for other reasons release. It seems like the perfect mechanism to comply with the rules about inclusion of nodes in the DTS. Vendors are free to document these nodes and don't require the Linux kernel include them in the Documents directory to do so. There have been recent efforts to move this documentation to a third party to maintain.
