According to Ondrej Jirman, switching of the mux of CPUX clock is one of the sources of timer jumps on A64 (and maybe this will also lead to timer jump on H3).
This patchset tries to remove this mux by disabling the dividers in PLL-CPUX. Both the lack of reparent when relocking and the prevention of PLL-CPUX dividers are behaviors of the BSP kernel.
