+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.
+
+  More information can be found at
