| 13 | This controller is mounted on development boards for Marvell's Link Street |
| 14 | family of Ethernet switches. It allows you to configure the switch's registers |
| 15 | using the standard MDIO interface. |
| 16 | |
| 17 | Since the device is connected over USB, there is no strict requirement of |
| 18 | having a device tree representation of the device. But in order to use it with |
| 19 | the mv88e6xxx driver, you need a device tree node in which to place the switch |
| 20 | definition. |
