Subject: [PATCH v3 0/4] asus-ec-sensors: add support for board families

Users provided information for boards from AMD-400 and sTRX40 families
and demonstrated that sensor addresses differ from those for the AMD-500
family. Also the AMD-400 family board uses the global ACPI lock instead
of a dedicated mutex to guard access to the hardware.

This patchset implements required changes to support other board
families:
 - per-family sensor definitions
 - options to choose hardware/state guard mutex: an AML mutex or the
   global ACPI lock.

These changes are used to add support for the PRIME X470-PRO board.


Changes in 
v3:
 - Added family_unknown member to the board_family enum to ensure the
	 default value of 0 is not a valid family value.
 - Added a note explaining why module_platform_driver_probe() is chosen
	 over module_platform_driver().

v2:
 - Removed the case without ACPI mutex where the state was guarded using
         the normal mutex. After receiving an update from user that case
         turned out to be non-existent.
 - Removed the __initconst attribute from the board data array.
 - Updated documentation to include the special string for the mutex
         path module parameters which make the driver use the global ACPI
         lock.

Eugene Shalygin (4):
  hwmon: (asus-ec-sensors) introduce ec_board_info struct for board data
  hwmon: (asus-ec-sensors) implement locking via the ACPI global lock
  hwmon: (asus-ec-sensors) add support for board families
  hwmon: (asus-ec-sensors) add PRIME X470-PRO board
