broadcom: fix PHY_ID_BCM5481 entry in the id table

2016-01-23T03:47:51+00:00

[ Upstream commit 3c25a860d17b7378822f35d8c9141db9507e3beb ]

Commit fcb26ec5b18d ("broadcom: move all PHY_ID's to header")
updated broadcom_tbl to use PHY_IDs, but incorrectly replaced 0x0143bca0
with PHY_ID_BCM5482 (making a duplicate entry, and completely omitting
the original). Fix that.

net: dp83640: fix broken calibration routine.

2015-06-22T23:55:51+00:00

[ Upstream commit 397a253af5031de4a4612210055935309af4472c ]

Currently, the calibration function that corrects the initial offsets
among multiple devices only works the first time.  If the function is
called more than once, the calibration fails and bogus offsets will be
programmed into the devices.

In a well hidden spot, the device documentation tells that trigger indexes
0 and 1 are special in allowing the TRIG_IF_LATE flag to actually work.

This patch fixes the issue by using one of the special triggers during the
recalibration method.

net: phy: Allow EEE for all RGMII variants

2015-06-22T23:55:50+00:00

[ Upstream commit 7e14069651591c81046ffaec13c3dac8cb70f5fb ]

RGMII interfaces come in multiple flavors: RGMII with transmit or
receive internal delay, no delays at all, or delays in both direction.

This change extends the initial check for PHY_INTERFACE_MODE_RGMII to
cover all of these variants since EEE should be allowed for any of these
modes, since it is a property of the RGMII, hence Gigabit PHY capability
more than the RGMII electrical interface and its delays.

net: phy: Fix verification of EEE support in phy_init_eee

2015-03-18T12:22:27+00:00

[ Upstream commit 54da5a8be3c1e924c35480eb44c6e9b275f6444e ]

phy_init_eee uses phy_find_setting(phydev->speed, phydev->duplex)
to find a valid entry in the settings array for the given speed
and duplex value. For full duplex 1000baseT, this will return
the first matching entry, which is the entry for 1000baseKX_Full.

If the phy eee does not support 1000baseKX_Full, this entry will not
match, causing phy_init_eee to fail for no good reason.

Fixes: 3e7077067e80c ("phy: Expand phy speed/duplex settings array")

net: phy: fix a bug when verify the EEE support

2013-05-28T06:30:09+00:00

The phy_init_eee has to exit with an error when the
local device and its link partner both do not support EEE.
So this patch fixes a problem when verify this.

 "GENERIC_GPIO now synonymous with GPIOLIB.  There are no longer any
  valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it
  is possible to do so which has been causing confusion and breakage.
  This branch does the work to completely eliminate GENERIC_GPIO."

GENERIC_GPIO is now equivalent to GPIOLIB and features that depended on
GENERIC_GPIO can now depend on GPIOLIB to allow removal of this option.

Also fix some comment formatting to make it consistent and to comply

phy: Elimination the forced speed reduction algorithm.

2013-03-27T17:10:43+00:00

In case of fixed speed set up for a NIC (e.g. ethtool -s eth0 autoneg off speed
100 duplex full) with an ethernet cable plugged off, the mentioned algorithm
slows down a NIC speed, so further cable hook-up leads to nonoperable link state.
