This patch attempts to make it generic enough so other parts of the
kernel can also provide their own implementation of scale_freq_tick()
callback, which is called by the scheduler periodically to update the
per-cpu freq_scale variable.
The implementations now need to provide struct scale_freq_tic
Hi,
I focused for now on the design of the solution and mostly on the
generic code in arch_topology.c, as that will then impact the arm64
code.
