But given there're already others except this one exist, and I believe no one want to give up their efforts. Also I think it's not exactly the same feauture provided by those drivers, so can we make some trade-off to combine those drivers into one and add the Signed-off-by for all the anthors? One agreement for all of us is to upstream the ACPI PCI for ARM64 asap!
