Andrew Halaney 84f78178b6 arm64: dts: ti: k3-j784s4-evm: Assign only lanes 0 and 1 to PCIe1 ... Currently PCIe1 is setup to use SERDES0 lanes 0 thru 3, and USB0 is setup to use SERDES0 lane 3 as well. This overlap in lanes causes the following reset related lane splat: [ 4.846266] WARNING: CPU: 4 PID: 308 at drivers/reset/core.c:792 __reset_control_get_internal+0x128/0x160 ...

[ 4.846577] cdns-torrent-phy 5060000.serdes: phy@0: failed to get reset Let's limit the PCIe1 SERDES0 lanes to 0 and 1 to avoid overlap here. This works since PCIe1 operates in x2 mode and doesn't need 4 SERDES0 lanes.
