net: phy: marvell: add support for MV88E6250 family internal PHYs

2024-05-07T22:17:52+00:00

The embedded PHYs of the 88E6250 family switches are very basic - they do not even have an Extended Address / Page register. This adds support for the PHYs to the driver to set up PHY interrupts and retrieve error stats. To deal with PHYs without a page register, "simple" variants of all stat handling functions are introduced. The code should work with all 88E6250 family switches (6250/6220/6071/ 6070/6020). The PHY ID 0x01410db0 was read from a 88E6020, under the assumption that all switches of this family use the same ID. The spec only lists the prefix 0x01410c00 and leaves the last 10 bits as reserved, but that seems too unspecific to be useful, as it would cover several existing PHY IDs already supported by the driver; therefore, the ID read from the actual hardware is used.

net: phy: marvell10g: fix differentiation of 88X3310 from 88X3340

2021-07-11T17:02:33+00:00

It seems that we cannot differentiate 88X3310 from 88X3340 by simply looking at bit 3 of revision ID. This only works on revisions A0 and A1. On revision B0, this bit is always 1. Instead use the 3.d00d register for differentiation, since this register contains information about number of ports on the device.

net: phy: marvell: fix detection of PHY on Topaz switches

2021-04-12T21:20:19+00:00

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 BugLink: https://github.com/globalscaletechnologies/linux/issues/1 Fixes: fee2d546414d ("net: phy: marvell: mv88e6390 temperature sensor reading") Reviewed-by: Marek Behún Reviewed-by: Andrew Lunn Signed-off-by: David S.

net: phy: add Marvell 88X2222 transceiver support

2021-03-15T21:50:28+00:00

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 Signed-off-by: David S. Miller
