We are introducing new driver without previous non-dts bindings, so
there is no need for .name fields.

Just to be clear, the '.name' field should only be removed for clk_parent_data?

Yes. The .fw_name references the name from dts "clock-names" array. .name predates that and uses the global system clock names. It should not be used if all dts files for the platform were using clock-names.
