[ Upstream commit 3e899fec5dfce37701d49d656954a825275bf867 ]

While trying to solve a bugreport on bugzilla, i learned that
some devices (for example the Dell XPS 17 9710) provide a more
recent DDV WMI interface (version 3).
Since the new interface version just adds an additional method,
no code changes are necessary apart from whitelisting the version.

<title>platform/x86: nvidia-wmi-ec-backlight: Add force module parameter</title>

<content type='text'>
commit 0d9bdd8a550170306c2021b8d6766c5343b870c2 upstream.

On some Lenovo Legion models, the backlight might be driven by either
one of nvidia_wmi_ec_backlight or amdgpu_bl0 at different times.

When the Nvidia WMI EC backlight interface reports the backlight is
controlled by the EC, the current backlight handling only registers
nvidia_wmi_ec_backlight (and registers no other backlight interfaces).

This hides (never registers) the amdgpu_bl0 interface, where as prior
to 6.1.4 users would have both nvidia_wmi_ec_backlight and amdgpu_bl0
and could work around things in userspace.

Add a force module parameter which can be used with acpi_backlight=native
to restore the old behavior as a workound (for now) by passing:

"acpi_backlight=native nvidia-wmi-ec-backlight.force=1"

Every power mode of static power slider has its own AC and DC power
settings.

When the power source changes from AC to DC, corresponding DC thermals
were not updated from PMF config store and this leads the system to always
run on AC power settings.

Fix it by registering with power_supply notifier and apply DC settings
upon getting notified by the power_supply handler.

settings.

When the power source changes from AC to DC, corresponding DC thermals
were not updated from PMF config store and this leads the system to always
run on AC power settings.

Fix it by registering with power_supply notifier and apply DC settings
upon getting notified by the power_supply handler.
