Thank you for reply, but this is something which we did not want to hear :-( There is an issue in the latest pcieuart8997_combo_v4.bin firmware file which NXP sent to linux-firmware repository and it is really needed to fix this issue. It was sent by NXP, so it is expected that NXP do it. And because it is binary-only file, people outside of NXP cannot do it. Would you be able to look at this firmware issue as the last thing? Or as Gérald wrote, could NXP provide source code of that firmware? So people outside of NXP could look at it? If firmware requires signing NDA (either individually or via company), then some professional skilled kernel developers can do it.
