This looks like something generic which other systems might be able to use and not specific to the HiSilicon SoC - does this belong in either the Designware code or the subsystem code?

But I have neither Designware spec nor designware code. I only got this code from Hisilicon.

Could any guy help to check whether this piece of code is in original designware code?
