It seems that Windows is only using the ACPI GPIO resources and never looks at the part of the _DSM return value which encodes the pin number. For example on a Terra Pad 1262 v2 the following messages are printend: int3472-discrete INT3472:01: reset \_SB.GPI0 pin number mismatch _DSM 103 resource 359 int3472-discrete INT3472:01: powerdown \_SB.GPI0 pin number mismatch _DSM 207 resource 335 int3472-discrete INT3472:02: reset \_SB.GPI0 pin number mismatch _DSM 101 resource 357 Notice for the 2 reset pins that the _DSM value is off by 256, this is caused by there only being 8 bits reserved in the _DSM return value for the pin-number. As for the powerdown pin, testing has shown that the pin-number 335 from the ACPI GPIO resource is correct and the _DSM value is bogus. Lower the warning about these mismatches to a debug message and only look at the lower 8 bits of the GPIO resource pin numbers.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
