Pull ACPI updates from Rafael Wysocki:
 "These update the ACPICA code in the kernel to the most recent upstream
  revision (20200110), add new hardware support to a handful of ACPI
  drivers, make the ACPI fan driver expose power states information for
  fans, add some more quirks, fix bugs and clean up assorted things.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision 20200110
     including:
      - Update of copyright notices to 2020 (Bob Moore).
      - Dispatcher fix to always generate buffer objects for the ASL
        create_field() operator (Maximilian Luz).
      - Debugger cleanup (Colin Ian King).
      - Disassembler change to create buffer fields in
        ACPI_PARSE_LOAD_PASS1 (Erik Kaneda).
      - UNIX line ending support for non-windows builds in acpisrc (Erik
        Kaneda).

   - Update the list of ACPICA maintainers (Rafael Wysocki).

   - Add Intel Tiger Lake ACPI device IDs to the ACPI DPTF, ACPI fan,
     int340x_thermal and intel-hid drivers (Gayatri Kammela).

   - Make the ACPI fan driver create additional sysfs attributes to
     expose power states information for fans (Srinivas Pandruvada).

   - Fix up the ACPI battery driver to deal with unexpected battery
     capacity information in a better way (Hans de Goede).

   - Add ACPI backlight quirks for Lenovo E41-25/45 and MSI MS-7721
     boards (Aaron Ma, Hans de Goede).

   - Add DMI quirk for Razer Blade Stealth 13 late 2019 lid switch to
     the ACPI button driver (Jason Ekstrand).

   - Drop TIMER_DEFERRABLE from the GHES polling mode timer function
     flags to make it run precisely at the configured time (Bhaskar
     Upadhaya).

   - Fix race condition related to the reference counting of query
     handlers in the ACPI EC driver (Rafael Wysocki).

   - Fix ACPI tools build issue (Zhengyuan Liu).

   - Replace dma_request_slave_channel() with dma_request_chan() in the
     firmware guide documentation for ACPI (Peter Ujfalusi).

   - Fix typo in a comment and clean up function parameter data type
     inconsistencies (Kacper Piwiński, Tian Tao)"

+===========================
+ACPI Fan Performance States
+===========================
+
+When the optional _FPS object is present under an ACPI device representing a
+fan (for example, PNP0C0B or INT3404), the ACPI fan driver creates additional
+"state*" attributes in the sysfs directory of the ACPI device in question.
+These attributes list properties of fan performance states.
+
+For more information on _FPS refer to the ACPI specification at:
+
+http://uefi.org/specifications
+
+For instance, the contents of the INT3404 ACPI device sysfs directory
+may look as follows::
+
+ $ ls -l /sys/bus/acpi/devices/INT3404:00/
+ total 0
+...
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state0
+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state1

+ -r--r--r-- 1 root root 4096 Dec 13 20:38 state9
+ -r--r--r-- 1 root root 4096 Dec 13 01:00 status
+ ...
+
+where each of the "state*" files represents one performance state of the fan
+and contains a colon-separated list of 5 integer numbers (fields) with the
+following interpretation::
+
+control_percent:trip_point_index:speed_rpm:noise_level_mdb:power_mw
+
+* ``control_percent``: The percent value to be used to set the fan speed to a
+  specific level using the _FSL object (0-100).
+
+* ``trip_point_index``: The active cooling trip point number that corresponds
+  to this performance state (0-9).
+
+* ``speed_rpm``: Speed of the fan in rotations per minute.
+
+* ``noise_level_mdb``: Audible noise emitted by the fan in this state in
+  millidecibels.
+
+* ``power_mw``: Power draw of the fan in this state in milliwatts.
+
+For example::
+
+ $cat /sys/bus/acpi/devices/INT3404:00/state1
+ 25:0:3200:12500:1250
+
+When a given field is not populated or its value provided by the platform
+firmware is invalid, the "not-defined" string is shown instead of the value.
