[U-Boot] [PATCH v3 5/8] Create PHY Lib for U-Boot
Andy Fleming

Fri Apr 8 04:56:04 CEST 2011
Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme. The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support
The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).
The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.
We now have MDIO drivers and PHY drivers
An MDIO driver provides:
read
write
reset
A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed
The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()
Each PHY driver can be configured separately, or all at once using
phylib_all_drivers.h (added in the patch which adds the drivers)
In the process, cleaned up a number of whitespace issues in miiphyutil.c

v3:
* Made mii_dev->name an array, and added a warning for if someone ever
tries to register a bus with more than 32 characters
* Fixed some minor formatting issues
* Changed phy_read and phy_write to be inline functions in phy.h
* Moved mii_dev definition to phy.h (necessary for phy_read/phy_write)
* Split out 10G support so it's only built if CONFIG_PHYLIB_10G is defined
* Removed constants stolen from linux, and added linux/mdio.h and
linux/ethtool.h
* Tweaked a number of things in those headers to get things to compile
* Statically initialize the phy_drivers list_head
v2:
* Fixed some sparse warnings/errors
* Changed headers for new files to GPL v2+
* Removed the unexplained 500ms delay after autonegotiation
