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