net: phy: marvell: Support SFP through phy_port interface

2026-01-14T02:52:35+00:00

Convert the Marvell driver (especially the 88e1512 driver) to use the phy_port interface to handle SFPs. This means registering a .attach_port() handler to detect when a serdes line interface is used (most likely, and SFP module).

net: phy: marvell: Fix 88e1510 downshift counter errata

2025-09-10T02:30:51+00:00

The 88e1510 PHY has an erratum where the phy downshift counter is not cleared after phy being suspended(BMCR_PDOWN set) and then later resumed(BMCR_PDOWN cleared). This can cause the gigabit link to intermittently downshift to a lower speed. Disabling and re-enabling the downshift feature clears the counter, allowing the PHY to retry gigabit link negotiation up to the programmed retry count times before downshifting. This behavior has been observed on copper links.

net: phy: marvell: Align set_loopback() implementation

2025-03-20T07:45:08+00:00

Use genphy_loopback() to disable loopback like ksz9031_set_loopback(). This way disable loopback is implemented only once within genphy_loopback() and the set_loopback() implementations look similar. Also fix comment about msleep() in the out-of loopback case which is not executed in the out-of loopback case.

net: phy: Allow loopback speed selection for PHY drivers

2025-03-20T07:45:08+00:00

PHY drivers support loopback mode, but it is not possible to select the speed of the loopback mode. The speed is chosen by the set_loopback() operation of the PHY driver. Same is valid for genphy_loopback(). There are PHYs that support loopback with different speeds. Extend set_loopback() to make loopback speed selection possible.
