[PATCH 1/4] dt-bingings: PCI: Remove the num-lanes from Required properties

From: Z.q. Hou
Date: Mon Aug 12 2019 - 00:22:25 EST


From: Hou Zhiqiang <Zhiqiang.Hou@xxxxxxx>

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 has been added in the Optional properties. This
patch is to remove it from the Required properties.
