Hi all, This short series adds the missing bits to support Apple T2 platforms. There are two quirks: these devices have firmware that requires the host to provide a blob of randomness as a seed (presumably because the chipsets lack a proper RNG), and the module/antenna information that is used for Apple firmware selection and comes from the Device Tree on ARM64 systems (already upstream) needs to come from ACPI on these instead. Changes since the megaseries from a ~year ago: made the ACPI code bail if there is no module-instance, so we don't try to get the antenna info at all in that case (as suggested by Arend). Made the randomness conditional on an Apple OTP being present, since it's not known to be needed on non-Apple firmware.
