phy: micrel: Disable auto negotiation on startup

2016-03-01T21:52:09Z

Disable auto negotiation on init to properly detect an already plugged cable at boot. At boot, when the phy is started, it is in the PHY_UP state. However, if a cable is plugged at boot, because auto negociation is already enabled at the time we get the first interrupt, the phy is already running. But the state machine then switches from PHY_UP to PHY_AN and calls phy_start_aneg(). phy_start_aneg() will not do anything because aneg is already enabled on the phy. It will then wait for a interrupt before going further. This interrupt will never happen unless the cable is unplugged and then replugged. It was working properly before 321beec5047a (net: phy: Use interrupts when available in NOLINK state) because switching to NOLINK meant starting polling the phy, even if IRQ were enabled.

phy: micrel: Ensure interrupts are reenabled on resume

2016-03-01T21:52:08Z

At least on ksz8081, when getting back from power down, interrupts are disabled. ensure they are reenabled if they were previously enabled. This fixes resuming which is failing on the xplained boards from atmel since 321beec5047a (net: phy: Use interrupts when available in NOLINK state) Fixes: 321beec5047a (net: phy: Use interrupts when available in NOLINK state) Signed-off-by: Alexandre Belloni Signed-off-by: David S.

phy: marvell: Fix and unify reg-init behavior

2016-02-17T21:20:40Z

For the Marvell 88E1510, marvell_of_reg_init was called too late, in the config_aneg function. Since commit 113c74d83eef ("net: phy: turn carrier off on phy attach"), this lead to the link not coming up at boot anymore, due to the phy state machine being stuck at waiting for interrupts (off by default on the 88E1510). For seven other Marvell PHYs, marvell_of_reg_init was not called at all. Add a generic marvell_config_init function, which in turn calls marvell_of_reg_init. PHYs, which already have a specific config_init function with a call to marvell_of_reg_init, are left untouched. The generic marvell_config_init function is called for all the others, to get consistent behavior across all Marvell PHYs.

phy: keep pause flags in phy driver features

2016-02-17T15:48:07Z

genphy_config_init() masked out pause flags set in phy driver structure. Pause flags needs to be preserved in phydev->supported & phydev->advertising. Signed-off-by: Woojung Huh Signed-off-by: David S. Miller

net: phy: bcm7xxx: Remove wildcard entries

2016-02-16T19:55:36Z

Remove the two wildcard entries, they serve no purpose and will match way too many devices, some of them being covered by the driver in drivers/net/phy/broadcom.c. Remove the now unused bcm7xxx_dummy_config_init() function which would produce a warning.

net: phy: bcm7xxx: Fix bcm7xxx_config_init() check

2016-02-16T19:55:35Z

Since we were wrongly advertising gigabit features for these 10/100 only Ethernet PHYs, bcm7xxx_config_init() which is supposed to apply workaround would have not run since the check would be true, now that we have fixed the PHY features, remove that check since it has no reasoning to be there anymore.

net: phy: bcm7xxx: Fix 40nm EPHY features

2016-02-16T19:55:35Z

The PHY entries for BCM7425/29/35 declare the 40nm Ethernet PHY as being 10/100/1000 capable, while this is just a 10/100 capable PHY device, fix that.

net: phy: bcm7xxx: Fix shadow mode 2 disabling

2016-02-16T19:55:35Z

The clear and set masks in the call to phy_set_clr_bits() called from bcm7xxx_config_init() are inverted. We need to fix this by swapping the two arguments, that is, set 0 bits, but clear the shade mode 2 enable bit.

net: phy: smsc: Fix disabling energy detect mode

2016-01-21T20:06:03Z

When the lan87xx_read_status function is getting called the energy detect mode is enabled again even if it has been disabled by device tree. Added private struct to check the energy detect status. Signed-off-by: Teresa Remmet Signed-off-by: David S. Miller
