[PATCH V2] phy: Generalise "auto-negotiation done" function, move generic PHY code to phy_device.c

From: Alexander Sverdlin <hidden>
Date: 2012-09-13 07:20:12
Subsystem: broadcom ethernet phy drivers, documentation, ethernet phy library, networking drivers, networking [general], ptp hardware clock support, the rest · Maintainers: Florian Fainelli, Jonathan Corbet, Andrew Lunn, Heiner Kallweit, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Richard Cochran, Linus Torvalds

From: Alexander Sverdlin <redacted>

Generalise "auto-negotiation done" function, move generic PHY code to phy_device.c 

Not all devices have "auto-negotiation done" bit at the place, as expected by
phy_aneg_done() in phy.c. Example of such device is Marvell 88E61xx Ethernet 
switch which could be controlled by Linux PHY layer, if struct phy_driver had
abstraction for above function. So move hardware-dependent implementation details
for "generic" PHY to phy_device.c, and modify all PHY drivers to use new field.
Now phy.c contains only high-level state-machine functionality, leaving 
hardware-layer to different drivers.
V2 is patch against net-next, as one additional PHY driver was added.
