Meson SoCs clock controllers use the string comparison method to describe parent relation between the clocks, which is not optimized. Its also use bypass clock made from device-tree clock to provide an input clock which can be access through global name, but it still not optimal. A recent patch [0] allows parents to be directly specified with device-tree clock name or without string names from localy declared clocks. This patchset replaces clock string names by clock pointers (as possible), removes bypass clocks and uses directly device-tree clock names in parent assignment. Tested on GXL, GXBB, Meson8b, AXG SoCs by comparing the clock summary (orphan too) before and after migration. [0] commit fc0c209c147f ("clk: Allow parents to be specified without string names") Change since v1: - Improve clock parent assignment for "fixme" using name instead of fw_name.
