2022-10-03net: sfp: augment SFP parsing with phy_interface_t bitmapRussell King
We currently parse the SFP EEPROM to a bitmap of ethtool link modes, and then attempt to convert the link modes to a PHY interface mode. While this works at present, there are cases where this is sub-optimal. For example, where a module can operate with several different PHY interface modes. To start addressing this, arrange for the SFP EEPROM parsing to also provide a bitmap of the possible PHY interface modes.

2022-06-15net: phy: marvell-88x2222: set proper phydev->portIvan Bornyakov
phydev->port was not set and always reported as PORT_TP. Set phydev->port according to inserted SFP module. Signed-off-by: Ivan Bornyakov <i.bornyakov@metrotek.ru> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-04-27net: phy: marvell-88x2222: enable autoneg by defaultIvan Bornyakov
There is no real need for disabling autonigotiation in config_init(). Leave it enabled by default. Signed-off-by: Ivan Bornyakov <i.bornyakov@metrotek.ru> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-04-14net: phy: marvell-88x2222: swap 1G/10G modes on autonegIvan Bornyakov
Setting 10G without autonegotiation is invalid according to phy_ethtool_ksettings_set(). Thus, we need to set it during autonegotiation. If 1G autonegotiation can't complete for quite a time, but there is signal in line, switch line interface type to 10GBase-R, if supported, in hope for link to be established. And vice versa. If 10GBase-R link can't be established for quite a time, and autonegotiation is enabled, and there is signal in line, switch line interface type to appropriate 1G mode, i.e. 1000Base-X or SGMII, if supported.

2021-04-14net: phy: marvell-88x2222: move read_status after config_anegIvan Bornyakov
No functional changes, just move read link status routines below autonegotiation configuration to make future functional changes more distinct. Signed-off-by: Ivan Bornyakov <i.bornyakov@metrotek.ru> Signed-off-by: David S. Miller <davem@davemloft.net>
2021-04-14net: phy: marvell-88x2222: check that link is operationalIvan Bornyakov
Some SFP modules uses RX_LOS for link indication. In such cases link will be always up, even without cable connected. RX_LOS changes will trigger link_up()/link_down() upstream operations. Thus, check that SFP link is operational before actual read link status. If there is no SFP cage connected to the tranciever, check only PMD Recieve Signal Detect register.

2021-03-15net: phy: add Marvell 88X2222 transceiver supportIvan Bornyakov
Add basic support for the Marvell 88X2222 multi-speed ethernet transceiver. This PHY provides data transmission over fiber-optic as well as Twinax copper links. The 88X2222 supports 2 ports of 10GBase-R and 1000Base-X on the line-side interface. The host-side interface supports 4 ports of 10GBase-R, RXAUI, 1000Base-X and 2 ports of XAUI. This driver, however, supports only XAUI on the host-side and 1000Base-X/10GBase-R on the line-side, for now. The SGMII is also supported over 1000Base-X. Interrupts are not supported. Internal registers access compliant with the Clause 45 specification. Signed-off-by: Ivan Bornyakov <i.bornyakov@metrotek.ru> Signed-off-by: David S. Miller <davem@davemloft.net>
