phy: Add support for SMSC LAN87xx PHYs

2011-12-05T22:07:59+00:00

This adds support for the SMSC LAN87xx PHYs.

Following PHYs can be used by set CONFIG_PHY_SMSC to config.
 - SMSC LAN8700
 - SMSC LAN8710/LAN8720
 - SMSC LAN8710/LAN8720

A setup of PHY was copied from linux kenrel.

Phy/Marvell: Rewrite the MV88E1111 phy config function based on kernel code

2011-12-05T20:59:00+00:00

The original m88e1111s_config() does not do the SGMII mode
initialization and is buggy. Rewrite the function according to
3.0.6 kernel function m88e1111_config_init() in drivers/net/phy/marvell.c

powerpc/85xx: wait for alignment before resetting SERDES RX lanes (SERDES9)

2011-10-20T21:01:37+00:00

The work-around for P4080 erratum SERDES9 says that the SERDES receiver
lanes should be reset after the XAUI starts tranmitting alignment signals.

phylib: wait for TN2020 to achieve SERDES lane alignment at startup

2011-10-14T04:38:11+00:00

Before the Teranetics TN2020 PHY can be used, the SERDES lanes need to be
aligned, so wait for lane alignment before completing the startup sequence.

Note that this process can take up to three seconds.

phylib: Work around bug in Teranetics PHY

2011-10-09T22:57:53+00:00

The Teranetics PHY does not properly report the link state
for fiber connections. The new PHY code actually checked the link,
and so the FM driver would refuse to talk over a linkless PHY.

But the link may actually be up, so now we always report it as up
for fiber connections on the tn2020.

Revert "phylib: remove a couple of redundant code lines"

2011-09-28T19:02:43+00:00

This reverts commit 041c542219af7f31c372d89b4c7c6f4c8064a8ce.

The lines removed by this commit weren't redundant. The logic is (and
probably should be better commented):

Find the intersection of the advertised capabilities of both sides of
the link (lpa).
From that intersection, find the highest capability we can run at
(that will be the negotiated link).

Now imagine that the intersection (lpa) is (LPA_100HALF | LPA_10FULL).

The code will now set phydev->speed to 100, and phydev->duplex to 1,
but this link does not support 100FULL.

Kudos to Andy Fleming  for binging this to
attention and for the explanation.

This change slightly improves readability of the phydev speed/duplex
assignment logic.

phylib: reset mii bus only if reset handler is registered

2011-09-09T22:07:55+00:00

This change allows to cope with a mii bus device registered using
miiphy_register(), which doesn't assign a default reset handler.

phy.c: make less verbose - turn printf() into debug()

2011-08-31T20:35:27+00:00

The PHY driver was too verbose and corrupted the boot message display
like this:

	...
	Net:   TSEC0 connected to Marvell 88E1111S
	TSEC1 connected to Marvell 88E1111S
	TSEC0, TSEC1
	...

Turn printf() into debug() so we het the expected output again:

	...
	Net:   TSEC0, TSEC1

phylib: Detect link on 10G devices correctly

2011-07-27T21:21:25+00:00

gen10g_startup() had 2 bugs:

1) It had a boolean logic error in checking the MMD mask, and
always checked all of them.

2) It checked devices which don't actually report link state, which
meant that it would never believe the link was fully up.

Fix the boolean logic, and then mask the MMD mask so only link-reporting
devices are checked.
