we may use rockchip_phy_typec struct in other driver, so split
it to separate header.

Hi Lin,

That patch does more than just split some structs to a public header,
it also introduces new structs and new parameters related to the
phy_config feature. IMHO you should first move the current structs and
introduce the new phy_config stuff in the following patch (4/5). I am
not sure about the maintainer preferences, but at least, if the
maintainer is fine like is now, I'd explain that you introduce new
elements in the commit message.

Best regards,
 Enric
