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.

For some board models ASUS uses the global ACPI lock to guard access to
the hardware, so do we.

2.35.1
We need to keep some more information about the current board than just
the sensors set, and with more boards to add the dmi id array grows
quickly. Our probe code is always the same so let's switch to a custom
test code and a custom board info array. That allows us to omit board
vendor string (ASUS uses two strings that differ in case) in the board
info and use case-insensitive comparison, and also do not duplicate
sensor definitions for such board variants as " (WI-FI)" when sensors
are identical to the base variant.
Also saves a quarter of the module size by replacing big dmi_system_id
structs with smaller ones.

This board is supposed to be handled by the asus-wmi-sensors driver,
but due to a buggy WMI implementation the driver and the official ASUS
software make the BIOS hang together with fan controls [1, 2].
This driver complements values provided by the SIO chip and does not
freeze the BIOS, as tested by a user [2].

Günter,
I forgot to add PRIME X470-PRO to the list of supported boards in
Documentation/hwmon/asus_ec_sensors.rst. Could you, please, add that?
It should be the first entry. Commit
8f8db4b5d10cc4a2a801514e677dd5205651b771. Or should I resend this
patch?
Thank you,
