Does that sound good to you, Tim? > Hi Shawn Guo, I agree with your suggestion. :-) The PCIe switch support patches can be added later, after the v7 patch for i.MX6 PCIe controller driver is merged. Also, if the PCIe switch support patches modify the synopsys designware PCIe driver (pcie-designware.c), it should be confirmed by other related people. Best regards, Jingoo Han
