Queued for 2.6.36 in git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next-2.6.git

With the move to phylib (commit e6b043d5

) I was seeing sporadic "MDIO write
timeout" messages. Measure of the actual time spent showed latency times of
more than 1600us.

This patch uses the MII event indication of the FEC hardware to detect
completion of MDIO transactions.

In fec open/close function, we need to use phy_connect and phy_disconnect
operation before we start/stop phy. Otherwise it will cause system hang.

Only call fec_enet_mii_probe() in open function, because the first open
action will cause NULL pointer error.

In Freescale BSP, commit 2d75a8fa9d7c7272b3b81268c2fb33a57be9a072 removes
regulator_consumer_supply VDDD which will be used by stgl5000 driver. So it
will give us an error message during booting:

'regulator: Unable to get requested regulator: VDDD'

This patch added it back and fix this error.

Short-term solution is to leave VUSB always on for USB OTG port
to work. Long-term solution would be for USB driver to enable the
necessary regulators. That will be addressed by a different CR.

The on-board PHY device of Freescale Babbage board is SMSC LAN8700, which is
supported by this CONFIG_SMSC_PHY driver in phylib. Since phylib is already
enabled in fec.c driver, to build in this SMSC_PHY driver will give us better
supporting of the PHY device.

The workqueue update for the leds-mc13892 driver introduced a regression
where machine would no longer suspend and resume, as the wrong type was
being retrieved from the platform drvdata.

This change updates the suspend and resume functions to use the struct
mc13892_led type.
