There are variants for devm or not and passing an accuracy or not passing one: - clk_hw_register_fixed_factor_fwname - clk_hw_register_fixed_factor_with_accuracy_fwname - devm_clk_hw_register_fixed_factor_fwname - devm_clk_hw_register_fixed_factor_with_accuracy_fwname The `struct clk_parent_data` init is extracted from __clk_hw_register_fixed_factor to each calling function. It is required to allow each function to pass whatever field they want, not only index.
