Hi, I am seeing an issue with next-20201211 with USB3380[1] based PCIe card (vid:pid 10b5:3380) on Jetson AGX Xavier. Card doesn't show up in the lspci output. In non working case (next-20201211): # lspci 0001:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad2 (rev a1) 0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13) 0005:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad0 (rev a1) In working case (v5.10-rc7): # lspci 0001:00:00.0 PCI bridge: Molex Incorporated Device 1ad2 (rev a1) 0001:01:00.0 SATA controller: Marvell Technology Group Ltd.

Could the failure be caused because dw_pcie_setup_rc() is called twice now in case of tegra194?
