Hello I have enabled the at803x driver to support the AR8031. However, only the generic PHY driver config_init get called.
phy_driver_register: 00000000
register generic for: Generic PHY, 0xffffffff
phy_driver_register: bbe15d54
register specific for: Atheros 8035 ethernet, 0x4dd072
phy_driver_register: bbe15d54
register specific for: Atheros 8030 ethernet, 0x4dd076
phy_driver_register: bbe15d54
register specific for: Atheros 8031 ethernet, 0x4dd074
call phy_init_hw
call config_init for: Generic PHY, 0xffffffff
I do not understand how to connect the AR802x phy driver to the device. Do I need to add something to the device tree?
