Would you be satisfied with “s/board/SoC used in board and it’s peripherials/” then?
Last time I looked there was no trace of CD8180 SoC in mainline Linux kernel.
So yes, you can give DTB to the kernel but if support is not there then kernel will not have drivers to attach to nodes in that DTB.
Let me take RK3588 as an example - your DTB can have info about both hdmi outputs and hdmi input but mainline would not use all of them as drivers are not merged yet.
