+         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.
