This is a follow-up to the ipq806x gcc modernize series. Manu cleanup changes and also some discoveries of wrong definition notice only with all these conversions. The first patch is an improvement of the clk_hw_get_parent_index. The original idea of clk_hw_get_parent_index was to give a way to access the parent index but for some reason the final version limited it to the current index. We change it to give the current parent if is not provided and to give the requested parent if provided. Any user of this function is updated to follow the new implementation. The patch 2 and 3 are some additional fixes for gcc. The first one is a fix that register the pxo and cxo fixed clock only if they are not defined in DTS. The patch 3 require some explaination. In short is a big HACK to prevent kernel panic with this series. The kpss-xcc driver is a mess. The Documentation declare that the clocks should be provided but for some reason it was never followed. In fact in the ipq8064 DTSI only the clocks for l2cc are declared but for cpu0 and cpu1 the clocks are not defined. The kpss-xcc driver use parent_names so the clks are ignored and never used so till now it wasn't a problem (ignoring the fact that they doesn't follow documentation at all) On top of that, the l2cc node declare the pxo clock in a really strange way. It's declared using the PXO_SRC gcc clock that is never defined in the gcc ipq8064 clock table. (the correct way was to declare a fixed clock in dts and reference that) To prevent any kind of problem we use the patch 3 and provide the clk for PXO_SRC in the gcc clock table. We manually provide the clk after gcc probe. Patch 4 is just a minor cleanup where we use the poll macro Patch 5 is the actually kpss-xcc conversion to parent data Patch 6-7 should be a fixup of a real conver case Patch 8 converts the krait-cc to parent_data Patch 9 give some love to the code with some minor fixup Patch 10 drop the hardcoded safe sel and use the new clk_hw_get_parent_index to get the safe parent index. (also I discovered that the parent order was wrong) Patch 11 is an additional fixup to force the reset of the muxes even more. Patch 12-13 are some additiona taken from the qsdk that were missing in the upstream driver Patch 14 converts krait-cc to yaml (should i also convert the kpss-scc driver?) Patch 15 finally adds all this stuff to the ipq8064 dtsi (and fix the stupid PXO_SRC phandle) Patch 16 conver the kpss driver to yaml and fix some Docuemntation errors I tested this series on a ipq8064 SoC by running a cache benchmark test to make sure the changes are correct and we don't silently cause regressions. Also I compared the output of the clk_summary every time and we finally have a sane output where the mux are correctly placed in the correct parent. (till now we had the cpu aux clock all over the place, probably never cause problems but who knows.)
