1OMAP Control Module bindings
2
3Control Module contains miscellaneous features under it based on SoC type.
4Pincontrol is one common feature, and it has a specialized support
5described in [1]. Typically some clock nodes are also under control module.
6Syscon is used to share register level access to drivers external to
7control module driver itself.

9See [2] for documentation about clock/clockdomain nodes.
