Sorry about that. I am using direct pointers to the new parent data here:

in drivers/clk/socfpga/clk-periph-s10.c

-       init.parent_names = parent_names;
+       init.parent_names = NULL;
+       init.parent_data = clks->parent_data;

The driver seems to work fine without having to add .fw_name.
