Where is the dependency expressed, so maintainers understand it should
go via one tree?

+title: Mobileye EyeQ5 clock controller
+
+description:
+  The EyeQ5 clock controller handles 10 read-only PLLs derived from the main
+  crystal clock. It also exposes one divider clock, a child of one of the PLLs.
+  Its registers live in a shared region called OLB.
