| 2 | |
| 3 | Control Module contains miscellaneous features under it based on SoC type. |
| 4 | Pincontrol is one common feature, and it has a specialized support |
| 5 | described in [1]. Typically some clock nodes are also under control module. |
| 6 | Syscon is used to share register level access to drivers external to |
| 7 | control module driver itself. |
| 8 | |
| 9 | See [2] for documentation about clock/clockdomain nodes. |
