Currently, there is only one clock input, so a match without specifying a clock name should work making this optional. But in your implementation, you do specify a clock name in devm_clk_get(). I'm not entirely sure, but that call might fail if it doesn't find the corresponding clock-names property. I think, either we should make this required and list the required entries here. Or the implementation probably needs to drop the clock name when looking up its input clock.
