+ help
+ The platform firmware on some systems expects Linux to return "5" as
+ the supported ACPI revision which makes it expose system configuration
+ information in a special way.
+
+ For example, based on what ACPI exports as the supported revision,
+ Dell XPS 13 (2015) configures its audio device to either work in HDA
+ mode or in I2S mode, where the former is supposed to be used on Linux
+ until the latter is fully supported (in the kernel as well as in user
+ space).
+
+ This option enables a DMI-based quirk for the above Dell machine (so
+ that HDA audio is exposed by the platform firmware to the kernel) and
+ makes it possible to force the kernel to return "5" as the supported
+ ACPI revision via the "acpi_rev_override" command line switch.
