Ethernet Phy

This is the common API for Ethernet Phy on ARMs.

Additional features are available in the documentation of the specific modules.

Platform Dependencies

The ethernet_phy API is partially chip- or platform-specific. While all platforms provide mostly the same functionality, there are some variations around how different bus types and clock tree structures are handled.

The following functions are available on all platforms, but there may be variations in the function signature (i.e. parameters) and behaviour. These functions are typically called by platform-specific parts of drivers, and applications that aren't intended to be portable:

• ethernet_phy_init()
• ethernet_phy_set_link()
• ethernet_phy_auto_negotiate()
• ethernet_phy_reset()
