+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.
+

+ compatible:
+ items:
