Subject: [PATCH 0/2] Add support for Microsoft Surface 3 power

Hi,

The MS Surface 3 is a reduced platform which doesn't use a regular chip
to report the battery information. Instead, they use ACPI Operation Region
to do the processing in the MSHW0011 driver.

This series aims at adding a reverse-engineered driver.
I am not sure whether the ACPICA patch is required because of a bug in the
ACPICA parsing or if MS just screwed up the DSDT. Anyway, it's there
and was judged as acceptable while we find out the exact issue (in
https://bugzilla.kernel.org/show_bug.cgi?id=106231 )

Cheers,
Benjamin
