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