You should use a name here. It makes future expansion of the binding
easier. devm_clk_get_optional() is probably better. If there is a real
error it will return an error. If the clock does not exist, you get a
NULL. Real errors should cause the problem to fail, but with a NULL
you can use the fallback value.

You also need to document the device tree binding.
