title: The Vertexcom MSE102x (SPI) Device Tree Bindings

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.
