| 12 | description: | |
| 13 | Vertexcom's MSE102x are a family of HomePlug GreenPHY chips. | |
| 14 | They can be connected either via RGMII, RMII or SPI to a host CPU. | |
| 15 | ||
| 16 | In order to use a MSE102x chip as SPI device, it must be defined as | |
| 17 | a child of an SPI master device in the device tree. | |
