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

+Subject: [PATCH 4/4] clk: qcom: kpss-xcc: convert to parent data API
+
+Convert the driver to parent data API. From the Documentation pll8_vote
+and pxo should be declared in the DTS so fw_name can be used instead of
+parent_names. Name is still used to save regression on old definition.

+
+Convert clk-rpm driver to parent_data API.
+We keep the old pxo/cxo_board parent naming to keep compatibility with
+old DT and we use the new pxo/cxo for new implementation where these
+clock are defined in DTS.
