+OMAP Control Module bindings
+
+Control Module contains miscellaneous features under it based on SoC type.
+Pincontrol is one common feature, and it has a specialized support
+described in [1]. Typically some clock nodes are also under control module.
+Syscon is used to share register level access to drivers external to
+control module driver itself.
+
+See [2] for documentation about clock/clockdomain nodes.
