The driver implements extended register access via indirect addressing through corresponding registers, and provides comprehensive device tree support for RGMII delay configuration. The rx-internal-delay-ps and tx-internal-delay-ps properties allow precise tuning of clock delays in 150 ps steps from 0 to 2250 ps.

The device doesn't implement autonegotiation, so the link is always reported as being up. The device implements both C22 and C45 MDIO access methods, but can only be discovered over C22, since the C45 MMD devices lack the MDIO_DEVID1 and MDIO_DEVID2 registers. The indirect C45 over C22 feature is not supported.
