net: phy: marvell: Limit errata to 88m1101

2017-09-15T17:30:58+00:00

commit f2899788353c13891412b273fdff5f02d49aa40f upstream.

The 88m1101 has an errata when configuring autoneg. However, it was
being applied to many other Marvell PHYs as well. Limit its scope to
just the 88m1101.

net: phy: fix marvell phy status reading

2017-09-15T17:30:49+00:00

commit 898805e0cdf7fd860ec21bf661d3a0285a3defbd upstream.

The Marvell driver incorrectly provides phydev->lp_advertising as the
logical and of the link partner's advert and our advert.  This is
incorrect - this field is supposed to store the link parter's unmodified
advertisment.

This allows ethtool to report the correct link partner auto-negotiation
status.

net: phy: handle state correctly in phy_stop_machine

2017-07-18T17:38:37+00:00

commit 49d52e8108a21749dc2114b924c907db43358984 upstream.

If the PHY is halted on stop, then do not set the state to PHY_UP.  This
ensures the phy will be restarted later in phy_start when the machine is
started again.

net: dp83640: Fix tx timestamp overflow handling.

2016-04-30T22:05:25+00:00

[ Upstream commit 81e8f2e930fe76b9814c71b9d87c30760b5eb705 ]

PHY status frames are not reliable, the PHY may not be able to send them
during heavy receive traffic. This overflow condition is signaled by the
PHY in the next status frame, but the driver did not make use of it.
Instead it always reported wrong tx timestamps to user space after an
overflow happened because it assigned newly received tx timestamps to old
packets in the queue.

This commit fixes this issue by clearing the tx timestamp queue every time
an overflow happens, so that no timestamps are delivered for overflow
packets. This way time stamping will continue correctly after an overflow.

broadcom: fix PHY_ID_BCM5481 entry in the id table

2015-12-30T02:25:58+00:00

commit 3c25a860d17b7378822f35d8c9141db9507e3beb upstream.

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.

2015-08-06T23:32:16+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.

phy:icplus:fix Auto Power Saving in ip101a_config_init.

2012-05-20T21:56:38+00:00

[ Upstream commit b3300146aa8efc5d3937fd33f3cfdc580a3843bc ]

This patch fixes Auto Power Saving configuration in ip101a_config_init
which was broken as there is no phy register write followed after
setting IP101A_APS_ON flag.

This patch also fixes the return value of ip101a_config_init.

Without this patch ip101a_config_init returns 2 which is not an error
accroding to IS_ERR and the mac driver will continue accessing 2 as
valid pointer to phy_dev resulting in memory fault.
