platform: add chrome platform directory

2013-11-20T23:51:03+00:00

It makes sense to split out the Chromebook/Chromebox hardware platform
drivers to a separate subdirectory, since some of it will be shared
between ARM and x86.

This moves over the existing chromeos_laptop driver without making
any other changes, and adds appropriate Kconfig entries for the new
directory. It also adds a MAINTAINERS entry for the new subdir.

Add trivial driver to disable Intel Smart Connect

2013-07-10T19:42:49+00:00

Intel Smart Connect is an Intel-specific ACPI interface for configuring
devices to wake up at regular intervals so they can pull down mail or other
internet updates, and then go to sleep again. If a user enables this in
Windows and then reboots into Linux, the device may wake up if it's put to
sleep. Since there's no Linux userland support for any of this, the machine
will then remain awake until something else puts it back to sleep.

I haven't figured out all that much about how this works (there's a bunch
of different ACPI calls available on the device), but this seems to be
enough to turn it off. We can add more features to this driver if anyone
ever cares about figuring out what the rest of the calls do or writing some
Linux userspace to implement the rest of it.

Add support driver for Intel Rapid Start Technology

2013-07-10T19:42:48+00:00

Intel Rapid Start Technology is a firmware-based suspend-to-disk
implementation. Once placed in S3, the device will wake once either a
timeout elapses or the battery reaches a critical level. It will then resume
to the firmware and copy the contents of RAM to a specialised partition, and
then power off the machine. If the user turns the machine back on the
firmware will copy the contents of the partition back to RAM and then resume
from S3 as normal.

This driver provides an interface for configuring the wakeup events and
timeout. It still requires firmware support and an appropriate suspend
partition.

platform/x86: Add driver for Apple gmux device

2012-03-26T19:05:25+00:00

Apple laptops with hybrid graphics have a device named gmux that
controls the muxing of the LVDS panel between the GPUs as well as screen
brightness. This driver adds support for the gmux device. Only backlight
control is supported initially.

toshiba_acpi: Refuse to load on machines with buggy INFO implementations

2012-03-22T13:31:53+00:00

Several Satellite models have a buggy implementation of the INFO method
that causes ACPI exceptions when executed:

 ACPI Error: Result stack is empty! State=ffff88012d70f800 (20110413/dswstate-98)
 ACPI Exception: AE_AML_NO_RETURN_VALUE, Missing or null operand (20110413/dsutils-646)

 toshiba_acpi: ACPI INFO method execution failed
 toshiba_acpi: Failed to query hotkey event

All known machines with this implementation also have a WMI interface
with event GUID 59142400-C6A3-40FA-BADB-8A2652834100 which is not seen
on any other models. Refuse to load toshiba_acpi on machines with this

platform/x86: drop deprecated asus_acpi driver

2012-03-20T16:02:18+00:00

asus_acpi only support old models, it has been deprecated since
2009 in favor of asus-laptop, it's not built by any (sane) distro,
so it is time to say good bye.

Thanks to Julien Lerouge and Karol Kozimor for the work they have
done on it, I would never have wrote asus-laptop and other asus
related drivers without asus_acpi.

of Fujitsu Tablet Computers, both convertibles and slates. Primarily
it allows for the automatic detection of the tablet/notebook mode for
convertible tablet pc's, and orientation for docked slates. It also
adds support for the application panel buttons usually found next to
the tablet screen, and docking station detection for slates.
