| 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. |
