From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>

On FSL Layerscape SoCs, the number of lanes assigned to PCIe
controller is not fixed, it is determined by the selected
SerDes protocol. The current num-lanes indicates the max lanes
PCIe controller can support up to, instead of the lanes assigned
to the PCIe controller. This can result in PCIe link training fail
after hot-reset.

Hou Zhiqiang (4):
  dt-bingings: PCI: Remove the num-lanes from Required properties
  PCI: dwc: Return directly when num-lanes is not found
  ARM: dts: ls1021a: Remove num-lanes property from PCIe nodes
  arm64: dts: fsl: Remove num-lanes property from PCIe nodes
