         Endpoint Descriptor (Piotr Maziarz).
       - iASL: NHLT: Rename linux specific strucures to device_info
         (Piotr Maziarz).
       - Add new ACPI 6.4 semantics to Load() and LoadTable() (Bob
         Moore).
       - Clean up double word in comment (Tom Rix).
       - Update copyright notices to the year 2022 (Bob Moore).

       - Replace zero-length array with flexible-array member (Gustavo
         A. R. Silva).
       - Interpreter: Add units to time variable names (Paul Menzel).
       - Add support for ARM Performance Monitoring Unit Table (Besar
         Wicaksono).
       - Inform users about ACPI spec violation related to sleep length
         (Paul Menzel).
       - iASL/MADT: Add OEM-defined subtable (Bob Moore).
       - Interpreter: Fix some typo mistakes (Selvarasu Ganesan).
       - Updates for revision E.d of IORT (Shameer Kolothum).
       - Use ACPI_FORMAT_UINT64 for 64-bit output (Bob Moore).

   - Improve debug messages in the ACPI device PM code (Rafael Wysocki).

   - Block ASUS B1400CEAE from suspend to idle by default (Mario
     Limonciello).

   - Improve handling of PCI devices that are in D3cold during system
     initialization (Rafael Wysocki).

   - Fix BERT error region memory mapping (Lorenzo Pieralisi).

   - Add support for NVIDIA 16550-compatible port subtype to the SPCR
     parsing code (Jeff Brasen).

   - Use static for BGRT_SHOW kobj_attribute defines (Tom Rix).

   - Fix missing prototype warning for acpi_agdi_init() (Ilkka
     Koskinen).

   - Fix missing ERST record ID in the APEI code (Liu Xinpeng).

   - Make APEI error injection to refuse to inject into the zero page
     (Tony Luck).

   - Correct description of INT3407 / INT3532 DPTF attributes in sysfs
     (Sumeet Pawnikar).

   - Add support for high frequency impedance notification to the DPTF
     driver (Sumeet Pawnikar).

   - Make mp_config_acpi_gsi() a void function (Li kunyu).

   - Unify Package () representation for properties in the ACPI device
     properties documentation (Andy Shevchenko).

   - Include UUID in _DSM evaluation warning (Michael Niewöhner)"
