Subject[PATCHv2 1/4] dt-bindings: PCI: designware: Remove the num-lanes from Required properties
Date
From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>

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.
