Add helpers to make locking/unlocking the MDIO bus easier. Signed-off-by: Heiner Kallweit Signed-off-by: David S. Miller

net: phy: remove phy_ethtool_sset()

2019-11-23T18:46:26+00:00

There are no users of phy_ethtool_sset() in the kernel anymore, and as of commit 3c1bcc8614db ("net: ethernet: Convert phydev advertize and supported from u32 to link mode"), the implementation is slightly buggy - it doesn't correctly check the masked advertising mask as it used to. Remove it, and update the phy documentation to refer to its replacement function. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: Jakub Kicinski

net: phy: add core phylib sfp support

2019-11-19T00:56:13+00:00

Add core phylib help for supporting SFP sockets on PHYs. This provides a mechanism to inform the SFP layer about PHY up/down events, and also unregister the SFP bus when the PHY is going away. Signed-off-by: Russell King Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: add support for clause 37 auto-negotiation

This patch adds support for clause 37 1000Base-X auto-negotiation. Signed-off-by: Heiner Kallweit Signed-off-by: Tao Ren Tested-by: René van Dorst Reviewed-by: Andrew Lunn Signed-off-by: David S. Miller

net: phy: extract pause mode

2019-10-05T01:11:08+00:00

Extract the update of phylib's software pause mode state from genphy_read_status(), so that we can re-use this functionality with PHYs that have alternative ways to read the negotiation results. Tested-by: tinywrkb Reviewed-by: Andrew Lunn Signed-off-by: Russell King Signed-off-by: David S. Miller

net: phy: extract link partner advertisement reading

2019-10-05T01:11:08+00:00

Move reading the link partner advertisement out of genphy_read_status() into its own separate function. This will allow re-use of this code by PHY drivers that are able to read the resolved status from the PHY.

Add genphy_c45_config_aneg() function to phy-c45.c

2019-08-28T03:21:15+00:00

Commit 34786005eca3 ("net: phy: prevent PHYs w/o Clause 22 regs from calling genphy_config_aneg") introduced a check that aborts phy_config_aneg() if the phy is a C45 phy. This causes phy_state_machine() to call phy_error() so that the phy ends up in PHY_HALTED state. Instead of returning -EOPNOTSUPP, call genphy_c45_config_aneg() (analogous to the C22 case) so that the state machine can run correctly. genphy_c45_config_aneg() closely resembles mv3310_config_aneg() in drivers/net/phy/marvell10g.c, excluding vendor specific configurations for 1000BaseT.

net: phy: let phy_speed_down/up support speeds >1Gbps

2019-08-14T00:14:06+00:00

So far phy_speed_down/up can be used up to 1Gbps only. Remove this restriction by using new helper __phy_speed_down. New member adv_old in struct phy_device is used by phy_speed_up to restore the advertised modes before calling phy_speed_down. Don't simply advertise what is supported because a user may have intentionally removed modes from advertisement. Signed-off-by: Heiner Kallweit Reviewed-by: Andrew Lunn Signed-off-by: Jakub Kicinski
