There are several issues with this:
1. You need to describe the type.
2. Description is not helpful (just copying the name of property) and
actually misleading because you do not put there the name of device node.
3. What is it? Looks like syscon (or sometimes called sysreg). If yes,
please use existing syscon bindings.

No need for quotes.
