This patch series implements two errata for TJA1120 and TJA1121.

The first errata applicable to both RGMII and SGMII version
of TJA1120 and TJA1121 deals with achieving full silicon performance.
The workaround in this case is putting the PHY in managed mode and
applying a series of PHY writes before the link gest established.

The second errata applicable only to SGMII version of TJA1120 and
TJA1121 deals with achieving a stable operation of SGMII after a
startup event.
The workaround puts the SGMII PCS into power down mode and back up
after restart or wakeup from sleep.

Changes in v2:
- use phy_id_compare() in case phydev->drv->phy_id is not set
