PCI Express M.2 Socket 1 utilizes a 3.3 V power source. The voltage source, 3.3 V, is expected to be available during the system’s stand-by/suspend state to support wake event processing on the communications card. Add vpcie3v3aux regulator to let this 3.3 V power source always on for PCIe M.2 Key E connector on i.MX8DXL EVK board.
