Subject: [PATCH 1/6] net: phy: at803x: support qca8081
|
|
genphy_c45_pma_read_abilities
|
|
|
|
qca8081 PHY supports to use genphy_c45_pma_read_abilities for
|
|
getting the PHY features supported except for the autoneg ability
|
|
|
|
but autoneg ability exists in MDIO_STAT1 instead of MMD7.1, add it
|
|
manually after calling genphy_c45_pma_read_abilities.
