net: phy: dp83822: use BMCR_ANENABLE instead of BMSR_ANEGCAPABLE for DP83620

2018-06-10T19:38:03+00:00

DP83620 register set is compatible with the DP83848, but it also supports
100base-FX. When the hardware is configured such as that fiber mode is
enabled, autonegotiation is not possible.

The chip, however, doesn't expose this information via BMSR_ANEGCAPABLE.
Instead, this bit is always set high, even if the particular hardware
configuration makes it so that auto negotiation is not possible [1]. Under
these circumstances, the phy subsystem keeps trying for autonegotiation to
happen, without success.

Hereby, we inspect BMCR_ANENABLE bit after genphy_config_init, which on
reset is set to 0 when auto negotiation is disabled, and so we use this
value instead of BMSR_ANEGCAPABLE.

net: phy: DP83822 initial driver submission

2017-10-11T21:14:32+00:00

Add support for the TI  DP83822 10/100Mbit ethernet phy.

The DP83822 provides flexibility to connect to a MAC through a
standard MII, RMII or RGMII interface.

In addition the DP83822 needs to be removed from the DP83848 driver
as the WoL support is added here for this device.
