That function is new to me, and I'm not sure how I'm supposed to use it?

It looks like clk_hw_register_gate, clk_hw_register_gate_parent_hw and
clk_hw_register_gate_parent_data all call __clk_hw_register_gate with
the same arguments, each expecting the parent_name, so they look
equivalent?

It looks like the original intent was to have the parent name, clk_hw
or clk_parent_data as argument, but the macro itself was copy pasted
without changing the arguments it's calling __clk_hw_register_gate
with?
