platform: x86: MLX_PLATFORM: select REGMAP instead of depending on it

2023-03-17T07:57:58+00:00

[ Upstream commit 7e7e1541c91615e9950d0b96bcd1806d297e970e ]

REGMAP is a hidden (not user visible) symbol. Users cannot set it
directly thru "make *config", so drivers should select it instead of
depending on it if they need it.

Consistently using "select" or "depends on" can also help reduce
Kconfig circular dependency issues.

Therefore, change the use of "depends on REGMAP" to "select REGMAP".

platform/x86: dell-ddv: Fix temperature scaling

2023-03-17T07:57:58+00:00

[ Upstream commit 0331b1b0ba65376ecf1c69414aa7696fef0930cb ]

After using the built-in UEFI hardware diagnostics to compare
the measured battery temperature, i noticed that the temperature
is actually expressed in tenth degree kelvin, similar to the
SBS-Data standard. For example, a value of 2992 is displayed as
26 degrees celsius.
Fix the scaling so that the correct values are being displayed.

Tested on a Dell Inspiron 3505.

platform/x86: dell-ddv: Return error if buffer is empty

2023-03-17T07:57:57+00:00

[ Upstream commit 36d44825faf42903a0b92dd49a9620e2cbdcbe18 ]

In several cases, the DDV WMI interface can return buffers
with a length of zero. Return -ENODATA in such a case for
proper error handling. Also replace some -EIO errors with
more specialized ones.

platform/x86: dell-ddv: Add support for interface version 3

2023-03-10T08:29:11+00:00

[ 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.

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

2023-02-25T10:13:29+00:00

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"
