So will every board have a copy of this exact code, verbatim ?
Yes for rk3399 based board.
Not sure why you ask this question, but I guess you still want these
parse happen in driver instead of board_init()?
I didn't make these code in dwc3 driver because other SoC dts are
different now, they are init in platdata data structure.
To be honest, I want to make the upstream code to support rk3399 dwc3,
but I don't want to touch too much code in other SoC.
Thanks,
