My name is stamped into maintainership for a big slew of DT bindings. Now that it is changing, switch it over to my kernel.org mail address, which will hopefully be stable for the rest of my life.

The Intel IXP4xx ethernet makes use of the IXP4xx NPE (Network
|
|
Processing Engine) and the IXP4xx Queue Manager to process
|
|
the ethernet frames. It can optionally contain an MDIO bus to
|
|
talk to PHYs.
