[PATCH 3/4] ARM: dts: ls1021a: Remove num-lanes property from PCIe nodes

2019-08-11 Thread Z.q. Hou
From: Hou Zhiqiang On FSL Layerscape SoCs, the number of lanes assigned to PCIe controller is not fixed, it is determined by the selected SerDes protocol in the RCW (Reset Configuration Word), and the PCIe link training is completed automatically base on the selected SerDes protocol, and the link
