This clock controller use the string comparison method to describe parent relation between the clocks, which is not optimized. A recent patch [0] allows parents to be specified without string names or with device-tree clock name by using a new assignment structure. Migrate to the new way by using .parent_hws where possible (when parent clocks are localy declared in the controller) and use .parent_data otherwise. Remove clk input helper and all bypass clocks (declared in probe function) which are no longer used since we are able to use device-tree clock name directly.
