title: Actions Semi Owl SoCs Ethernet MAC Controller



maintainers:

  - Cristian Ciocaltea <cristian.ciocaltea@gmail.com>



description: |

  This Ethernet MAC is used on the Owl family of SoCs from Actions Semi.

  It provides the RMII and SMII interfaces and is compliant with the

  IEEE 802.3 CSMA/CD standard, supporting both half-duplex and full-duplex

  operation modes at 10/100 Mb/s data transfer rates.
