Subject: [PATCH v1 04/26] ACPICA: Add UUIDs associated with TPM 2.0 devices

From: Armin Wolf <W_Armin@....de>

The Trusted Computing Group has designed multiple interface extensions
around TPM 2.0 devices including the ACPI start method, hardware
information and memory clear features. Add the associated UUIDs to the
list of known UUIDs so that the ASL compiler stops complaining about
them.
