This is based on Stephen's recent work allowing clk drivers to specify clk parents using struct clk_hw * or parsing DT phandles in the clk node. This series can be split into a few major parts: 1) The first patch is a small fix for clk debugfs representation. This was done before commit 1a079560b145 ("clk: Cache core in clk_fetch_parent_index() without names") was posted, so it might or might not be needed. Found this when checking my work using clk_possible_parents. 2) A bunch of CLK_HW_INIT_* helper macros are added. These cover the situations I encountered, or assume I will encounter, such as single internal (struct clk_hw *) parent, single DT (struct clk_parent_data .fw_name), multiple internal parents, and multiple mixed (internal + DT) parents. A special variant for just an internal single parent is added, CLK_HW_INIT_HWS, which lets the driver share the singular list, instead of having the compiler create a compound literal every time. It might even make sense to only keep this variant. 3) A bunch of CLK_FIXED_FACTOR_* helper macros are added. The rationale is the same as the single parent CLK_HW_INIT_* helpers. 4) Bulk conversion of CLK_FIXED_FACTOR to use local parent references, either struct clk_hw * or DT .fw_name types, whichever the hardware requires. 5) The beginning of SUNXI_CCU_GATE conversion to local parent references. This part is not done. They are included as justification and examples for the shared list of clk parents case. I realize this is going to be many patches every time I convert a clock type. Going forward would the people involved prefer I send out individual patches like this series, or squash them all together? Stephen, would it make sense for you to pick up the first 7 patches that touch the clk core? And then we can base our clk branch on top of those?
