Blaž Hrastnik b1f81b496b platform/x86: surface3_power: MSHW0011 rev-eng implementation
Patch was rebased on top of for-next. Thanks for your patience!

Blaž

I'm resubmitting this patch with review feedback addressed:

https://patchwork.kernel.org/patch/10584079/

The patch was previously not resubmitted because it required a change
that was reverted in the ACPICA. That has since been corrected:

9159c09a2a

We've been using this patch for a while and user reports confirm that it
works:

https://github.com/linux-surface/linux-surface

Previous description follows.

>8------------------------------------------------------8<

The MSHW0011 device is a chip that replaces the battery firmware
by using ACPI operation regions on the Surface 3.
It is unclear whether or not the chip will be reused somewhere else
(under Windows, the chip is called "Surface Platform Power Driver"
and the driver is provided by Microsoft).

The values have been obtained by reverse engineering, and are subject to
errors. Looks like it works on overall pretty well.

I couldn't manage to get the IRQ correctly triggered, so I am using a
good old polling thread to check for changes. This is something
to be fixed in a later version.

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 Restructured Text 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.
