Filename matching compatible, so missing "clk"

Drop "binding"

"generates and supplies" what?

Why "clkmgr", not "clk"? You did not call it Clock manager anywhere in
the description or title.

Keep the same order as in properties:

Filename the same as binding. Missing vendor prefix, entirely different
device name.

Same filename as binding.

But why do you need this file? Your device is not a reset controller.
