[PATCH net-next 2/2] net: lan966x: remove PHY reset support

From: Michael Walle
Date: Thu Apr 28 2022 - 07:41:11 EST


The PHY subsystem as well as the MIIM mdio driver (in case of the
integrated PHYs) will take care of the resets. A separate reset driver
isn't needed. There is no in-tree user of this feature. Remove the
support.
