Hou" List-Id: devicetree@vger.kernel.org From: Hou Zhiqiang The num-lanes is not a mandatory property, e.g. on FSL Layerscape SoCs, the PCIe link training is completed automatically base on the selected SerDes protocol, it doesn't need the num-lanes to set-up the link width. It is previously in both Required and Optional properties, let's remove it from the Required properties.
