I tried to assign different (already existing) clock nodes but no luck so far.
When I try to use init_uart_clock = 128000000, I can see it being reflected in the clk_summary (cat /sys/kernel/debug/clk/clk_summary) but I am still not able to get beyond 4Mbit.
So my fear is that even though the new clock is reflected by the kernel, it is not actually changed in hardware.
This is what clk_summary reports currently:
