+title: The Vertexcom MSE102x (SPI) Device Tree Bindings
+
+maintainers:

+
+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.
+
+ More information can be found at
