Yes. However, X11 is not actually correct (pretty much all dts files
have it wrong). This is the X11 license[1] which is explicitly for the
X Consortium and has a couple of extra clauses. While the MIT
license[2] is the text that most dts files actually use (while also
stating X11 license). It's obvious that everyone just copies and
pastes the license and has not consulted their lawyers.

Consult your lawyer. :)

But the clock is part of the board, not the soc. Or to put it another
way, it's not related to anything else, so it shouldn't be a child of
anything.
