(A newer version of the 6390 documentation removed temperature sensor section completely. In an older version, the above mentioned register is reserved, although it is R/W.

2021-04-12net: phy: marvell: fix detection of PHY on Topaz switchesPali Rohár1-3/+29
Since commit fee2d546414d ("net: phy: marvell: mv88e6390 temperature sensor reading"), Linux reports the temperature of Topaz hwmon as constant -75°C. This is because switches from the Topaz family (88E6141 / 88E6341) have the address of the temperature sensor register different from Peridot. This address is instead compatible with 88E1510 PHYs, as was used for Topaz before the above mentioned commit. Create a new mapping table between switch family and PHY ID for families which don't have a model number. And define PHY IDs for Topaz and Peridot families. Create a new PHY ID and a new PHY driver for Topaz's internal PHY. The only difference from Peridot's PHY driver is the HWMON probing method. Prior this change Topaz's internal PHY is detected by kernel as: PHY [...] driver [Marvell 88E6390] (irq=63) And afterwards as: PHY [...] driver [Marvell 88E6341 Family] (irq=63) Signed-off-by: Pali Rohár <pali@kernel.org> BugLink: https://github.com/globalscaletechnologies/linux/issues/1 Fixes: fee2d546414d ("net: phy: marvell: mv88e6390 temperature sensor reading") Reviewed-by: Marek Behún <kabel@kernel.org> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2021-02-16net: phy: marvell: Ensure SGMII auto-negotiation is enabled for 88E1111Robert Hancock1-5/+8
When 88E1111 is operating in SGMII mode, auto-negotiation should be enabled on the SGMII side so that the link will come up properly with PCSes which normally have auto-negotiation enabled. This is normally the case when the PHY defaults to SGMII mode at power-up, however if we switched it from some other mode like 1000Base-X, as may happen in some SFP module situations, it may not be, particularly for modules which have 1000Base-X auto-negotiation defaulting to disabled. Call genphy_check_and_restart_aneg on the fiber page to ensure that auto- negotiation is properly enabled on the SGMII interface.

2021-02-11net: phy: introduce phydev->portMichael Walle1-0/+1
At the moment, PORT_MII is reported in the ethtool ops. This is odd because it is an interface between the MAC and the PHY and no external port. Some network card drivers will overwrite the port to twisted pair or fiber, though. Even worse, the MDI/MDIX setting is only used by ethtool if the port is twisted pair. Set the port to PORT_TP by default because most PHY drivers are copper ones. If there is fibre support and it is enabled, the PHY driver will set it to PORT_FIBRE. This will change reporting PORT_MII to either PORT_TP or PORT_FIBRE; except for the genphy fallback driver.

The negotiation of flow control / pause frame modes was broken since commit fcf1f59afc67 ("net: phy: marvell: rearrange to use genphy_read_lpa()") moved the setting of phydev->duplex below the phy_resolve_aneg_pause call. Due to a check of DUPLEX_FULL in that function, phydev->pause was no longer set. Fix it by moving the parsing of the status variable before the blocks dealing with the pause frames. As the Marvell 88E1510 datasheet does not specify the timing between the link status and the "Speed and Duplex Resolved" bit, we have to force the link down as long as the resolved bit is not set, to avoid reporting link up before we even have valid Speed/Duplex.
