[PATCH v2 0/3] TI Ethernet PHY changes

The addition of the DP83867 driver to uboot was done in a generic way that
made it a bit difficult to bring in new PHY drivers.  The difficulty came in the
config flags and the phy_init function.  The change is to make the flags and
init for the DP83867 more specific to the DP83867 device to make way to add
more TI PHYs to uBoot.

In addition the DP8382X PHY is a generic PHY driver that does not need any
special handling to establish a link.  Customers have requested that at the very
least there be a way to know if the PHY attached is the PHY that is connected
as "Generic PHY" is not really descriptive.  These patches adds the
registrations for TI Generic PHYs to associcate a TI PHY ID with a PHY name.

Porting PHY helper routines to set and clear bits to facilitate easier side
porting of ethernet kernel drivers to uBoot.


Dan Murphy (3):
  net: phy: Add helper routines to set and clear bits
  net: phy: Add support for TI PHY init
  net: phy: Add DP8382x phy registration to TI PHY init

*Note: I dropped the DP83869 patch for now.
