0001 OMAP Control Module bindings
0002
0003 Control Module contains miscellaneous features under it based on SoC type.
0004 Pincontrol is one common feature, and it has a specialized support
0005 described in [1]. Typically some clock nodes are also under control module.
0006 Syscon is used to share register level access to drivers external to
0007 control module driver itself.
0008
0009 See [2] for documentation about clock/clockdomain nodes.
