| 8 | PHY support. | |
| 9 | ||
| 10 | This framework is designed to provide a generic interface for PHY | |
| 11 | devices. PHY devices are dedicated hardware that handle the physical | |
| 12 | layer of the protocols in the OSI model. | |
| 13 | PHYs are commonly used for high speed interfaces such as Serial-ATA | |
| 14 | or PCI express. | |
| 15 | The API provides functions to initialize/deinitialize the | |
| 16 | PHY, power on/off the PHY, and reset the PHY. It's meant to be as | |
| 17 | compatible as possible with the equivalent framework found in the | |
| 18 | linux kernel. | |

| 47 | help | |
| 48 | Support for a no-op PHY driver (stubbed PHY driver). | |
