[RFC PATCH 1/3] net: phy: Add a generic phy file for TI generic PHYs

Dan Murphy dmurphy at ti.com
Mon Apr 20 20:53:08 CEST 2020


Add a TI Generic init file that will initialize TI PHYs that follow that
not require special handling.  These PHYs can connect with the standard
MII register set.  This generice file will register the PHY IDs and
names of the PHYs so when the command 'mdio list' is executed the PHY
name will display as opposed to 'Generic PHY'.

The DP8382X PHY series is a generic PHY that requires the generic
registration.

The DP83867 driver was updated to rename the init to a more PHY specific
init call.
