+description:
+  i.MX BLK_CTL is a conglomerate of different GPRs that are
+  dedicated to a specific subsystem. Because it usually contains
+  clocks amongst other things, it needs access to the i.MX clocks
+  API. All the other functionalities it provides can work just fine
+  from the clock subsystem tree.
