What are you trying to achieve here? Do you want to use devm_clk_get on your driver? If so, you just need to list the clock your device needs on its device tree node, like for example
device: blah@0f0.... { .... clocks = <&gate 12>, <&clock>, <&whatever>; clock-names = "module", "ref", "sample"; }
And then you can pass "module", "ref" or "sample" to devm_clk_get to get the respective clock.
