[PATCH net-next 4/5] net: dsa: mv88e6xxx: remove unused 88E6165 register definitions

Russell King (Oracle)
2025-09-15T13:06:34Z

Remove the unused 88E6165 register definitions. For the port
registers, add a comment describing that each arrival and departure
offset is for a set of four registers that correspond with status,
two timestamp registers and the PTP sequence ID captured from the
packet.
