In this example, the clock output name of the clock provider is
the same as the clock input of the consumer, that is almost always
a bug and would not be a good example at all.
I assume the output name is correct and the input is not. If you
have access to the HDL source of the bcm6345-uart, please check
if the input has a proper name, otherwise just call it "uart"
or remove the clock-names property completely.
In the documentation enough, you must document the specific name
of the clock that is supposed to be used by the uart driver.
