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.
