These nodes are example nodes for the PCIe controller in "endpoint" mode. By default the controller is in "root complex" mode and there is already a DT node for the same. Examples should go in the bindings or other documentation. Remove this node.How we will support EP from now onwards, using overlays ?
They are already disabled, how do you support them today? Andrew
