Benson Leung 2ef392042d Platform: x86: chromeos_laptop : Add basic platform data for atmel devices
Add basic platform data to get the current upstream driver working
with the 224s touchpad and 1664s touchscreen.
We will be using NULL config so we will use the settings from the
devices' NVRAMs.

Matthew Garrett 445e8d007c ideapad-laptop: Depend on BACKLIGHT_CLASS_DEVICE instead of selecting it
Selecting BACKLIGHT_CLASS_DEVICE doesn't guarantee that any of its
dependencies are enabled, and these are complicated. Depending isn't ideal
for configuration UI purposes, but is probably more appropriate here.

Dmitry Torokhov c165b80cfe hp-wmi: fix handling of platform device
The driver will not quite work if someone unbinds the platform device
from the platform driver via sysfs (moreover it will bomb is the driver
built into the kernel as hp_wmi_bios_remove is marked as __exit and will
not be present in the kernel).

To fix it let's use platform_driver_probe() instead of
platform_driver_register(), which disables binding/unbinding via sysfs.
This also allows us to mark hp_wmi_bios_setup as __init and discard it
once module is initialized.

AceLan Kao a2a96f0c72 asus-wmi: add display toggle quirk
For machines with AMD graphic chips, it will send out WMI event and ACPI
interrupt at the same time while hitting the hotkey. BIOS will notify the
system the next display output mode throught WMI event code, so that
windows' application can show an OSD to tell the user which mode will be
taken effect. User can hit the display toggle key many times within 2
seconds to choose the mode they want. After 2 seconds, WMI dirver should
send a WMIMethod(SDSP) command to tell the BIOS which mode the user chose.
And then BIOS will raise another ACPI interrupt to tell the system to
really switch the display mode.

In Linux desktop, we don't have this kind of OSD to let users to choose
the mode they want, so we don't need to call WMIMethod(SDSP) to have
another ACPI interrupt. To simplify the problem, we just have to ignore
the WMI event, and let the first ACPI interrupt to send out the key event.

For the need, here comes another quirk to add machines with this kind of
behavior. When the WMI driver receives the display toggle WMI event, and
found the machin is in the list, it will do nothing and let ACPI video
driver to report the key event.

Maxim Mikityanskiy c11ac2aa52 msi-wmi: Add MSI Wind support
Add MSI Wind support to msi-wmi driver. MSI Wind has different GUID for
key events, different WMI key scan codes, it does not need filtering
consecutive identical events and it does not support backlight control
via MSIWMI_BIOS_GUID WMI. Tested on MSI Wind U100.

Maxim Mikityanskiy 03696e51d7 msi-laptop: Disable brightness control for new EC
It seems that existing brightness control works only for old EC models.
On newer ones auto_brightness access always timeouts and lcd_level
always shows 0. So disable brightness control for new EC models. It
works fine with ACPI video driver anyway.
