I already though about refactoring that code to a generic MIPS timer driver which could call the clk API to fetch the frequency either from device tree or a clk-provider driver. Optionally a SoC could replace this generic driver with a specialiced one. Until then it makes sense to make the two timer function weak. Alternatively we could conditionally compile arch/mips/cpu/time.c so that you can provide your own machine specific time.c -- - Daniel
