Hi Calvin That does not scale. Every driver doing its own thing. Each having its own bugs, maintenance overheads, documentation problems, no meta validation of the ACPI tables because every table is different, etc. Where is the Advanced in that? It sounds more like Primitive, Chaotic, Antiquated? Plus having it generic means there is one place which needs modifications when the ACPI standards committee does decide how this should be done. > If we plan to make this approach generic, then it may have to be put in: > Documentation/firmware-guide/acpi/ So looking in this directory, we have defacto standards, e.g. linux/Documentation/firmware-guide/acpi/dsd/leds.rst. So lets add another defacto standard, how you find a PHY. Andrew
