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.
