   4 Subject: [PATCH 3/4] clk: introduce (devm_)hw_register_mux_parent_data_table
   5  API
   6
   7 Introduce (devm_)hw_register_mux_parent_data_table new API. We have
   8 basic support for clk_register_mux using parent_data but we lack any API
   9 to provide a custom parent_map. Add these 2 new API to correctly handle
  10 these special configuration instead of using the generic
  11 __(devm_)clk_hw_register_mux API.
