Is it possible that UFS flash running at too high frequency in mainline?

[catmengi]

I found this line in android code dev-ref-clk-freq = <0> Found in kernel documentation that 0 means 19.2mhz but default freq(when dev-ref-clk-freq not specified) is ±26mhz. This issue may exist now because of change in clock driver that lead it to work properly and now ufs chip is at too high freq?
