net: phy: add registers to support 1000BASE-T1

2023-07-20T10:24:06+00:00

Add registers and definitions to support 1000BASE-T1. This includes the PCS Control and Status registers (3.2304 and 3.2305) as well as some missing bits on the PMA/PMD extended ability register (1.18) and PMA/PMD CTRL (1.2100) register.

net: phy: add genphy_c45_ethtool_get/set_eee() support

2023-02-13T11:12:31+00:00

Add replacement for phy_ethtool_get/set_eee() functions. Current phy_ethtool_get/set_eee() implementation is great and it is possible to make it even better: - this functionality is for devices implementing parts of IEEE 802.3 specification beyond Clause 22. The better place for this code is phy-c45.c - currently it is able to do read/write operations on PHYs with different abilities to not existing registers. It is better to use stored supported_eee abilities to avoid false read/write operations. - the eee_active detection will provide wrong results on not supported link modes. It is better to validate speed/duplex properties against supported EEE link modes. - it is able to support only limited amount of link modes. We have more EEE link modes... By refactoring this code I address most of this point except of the last one. Adding additional EEE link modes will need more work. Signed-off-by: Oleksij Rempel Signed-off-by: David S. Miller

net: phy: Add 10BASE-T1L support in phy-c45

2022-05-01T16:45:35+00:00

This patch is needed because the BASE-T1 uses different registers for status, control and advertisement to those already employed in the existing phy-c45 functions. Where required, genphy_c45 functions will now check whether the device supports BASE-T1 and use the specific registers instead: 45.2.7.19 BASE-T1 AN control register, 45.2.7.20 BASE-T1 AN status, 45.2.7.21 BASE-T1 AN advertisement register, 45.2.7.22 BASE-T1 AN LP Base Page ability register, 45.2.1.185 BASE-T1 PMA/PMD control register.

net: phy: Add BaseT1 auto-negotiation registers

2022-05-01T16:45:35+00:00

Added BASE-T1 AN advertisement register (Registers 7.514, 7.515, and 7.516) and BASE-T1 AN LP Base Page ability register (Registers 7.517, 7.518, and 7.519). Reviewed-by: Andrew Lunn Signed-off-by: Alexandru Tachici Signed-off-by: David S. Miller

net: phy: Add 10-BaseT1L registers

2022-05-01T16:45:35+00:00

The 802.3gc specification defines the 10-BaseT1L link mode for ethernet trafic on twisted wire pair. PMA status register can be used to detect if the phy supports 2.4 V TX level and PCS control register can be used to enable/disable PCS level loopback.
