Commit Message

Grygorii Strashko March 3, 2020, 4 p.m. UTC 
TI AM654x/J721E SoCs have the same PHY interface selection mechanism for
CPSWx subsystem as TI SoCs (AM3/4/5/DRA7), but registers and bit-fields
placement is different.

This patch adds corresponding support for TI AM654x/J721E SoCs PHY
interface selection.
