ACPI: x86: Clean up Asus entries in acpi_quirk_skip_dmi_ids[]

2024-11-22T20:10:23+00:00

The Asus entries in the acpi_quirk_skip_dmi_ids[] table are the only
entries without a comment which model they apply to. Add these comments.

The Asus TF103C entry also is in the wrong place for what is supposed to
be an alphabetically sorted list. Move it up so that the list is properly
sorted and add a comment that the list is alphabetically sorted.

ACPI: x86: Add skip i2c clients quirk for Acer Iconia One 8 A1-840

2024-11-22T20:10:23+00:00

The Acer Iconia One 8 A1-840 (not to be confused with the A1-840FHD which
is a different model) ships with Android 4.4 as factory OS and has the
usual broken DSDT issues for x86 Android tablets.

Add quirks to skip ACPI I2C client enumeration and disable ACPI battery/AC
and ACPI GPIO event handlers.

Also add the "INT33F5" HID for the TI PMIC used on this tablet to the list
of HIDs for which not to skip i2c_client instantiation, since we do want
an ACPI instantiated i2c_client for the PMIC.

ACPI: x86: Add adev NULL check to acpi_quirk_skip_serdev_enumeration()

2024-11-12T20:21:58+00:00

acpi_dev_hid_match() does not check for adev == NULL, dereferencing
it unconditional.

Add a check for adev being NULL before calling acpi_dev_hid_match().

At the moment acpi_quirk_skip_serdev_enumeration() is never called with
a controller_parent without an ACPI companion, but better safe than sorry.

ACPI: x86: Make UART skip quirks work on PCI UARTs without an UID

2024-11-12T20:20:33+00:00

The Vexia EDU ATLA 10 tablet (9V version) which shipped with Android 4.2
as factory OS has the usual broken DSDT issues for x86 Android tablets.

On top of that this tablet is special because all its LPSS island
peripherals are enumerated as PCI devices rather then as ACPI devices as
they typically are.

For the x86-android-tablets kmod to be able to instantiate a serdev client
for the Bluetooth HCI on this tablet, an ACPI_QUIRK_UART1_SKIP quirk is
necessary.

Modify acpi_dmi_skip_serdev_enumeration() to work with PCI enumerated
UARTs without an UID, such as the UARTs on this tablet.

Also make acpi_dmi_skip_serdev_enumeration() exit early if there are no
quirks, since there is nothing to do then.

And add the necessary quirks for the Vexia EDU ATLA 10 tablet.

This should compile with CONFIG_PCI being unset without issues because
dev_is_pci() is defined as "(false)" then.

ACPI: x86: Make Lenovo Yoga Tab 3 X90F DMI match less strict

2024-08-29T10:47:53+00:00

There are 2G and 4G RAM versions of the Lenovo Yoga Tab 3 X90F and it
turns out that the 2G version has a DMI product name of
"CHERRYVIEW D1 PLATFORM" where as the 4G version has
"CHERRYVIEW C0 PLATFORM". The sys-vendor + product-version check are
unique enough that the product-name check is not necessary.

Drop the product-name check so that the existing DMI match for the 4G
RAM version also matches the 2G RAM version.

Merge branches 'acpi-x86', 'acpi-fan', 'acpi-soc' and 'acpi-cppc'

2024-07-15T17:04:15+00:00

Merge changes in the ACPI x86-specific code, ACPI fan driverm ACPI LPSS
(Intel SoC) driver and the ACPI CPPC library for 6.11-rc1:

 - Switch the ACPI x86 utility code and the ACPI LPSS driver to new
   Intel CPU model defines (Tony Luck).

 - Add hwmon interface support to the ACPI fan driver (Armin Wolf).

 - Add sysfs entry for guaranteed performance to the ACPI CPPC library
   and replace a ternary operator with umax() in it (Petr Tesařík,
   Prabhakar Pujeri).

ACPI: x86: Force StorageD3Enable on more products

2024-06-07T18:24:07+00:00

A Rembrandt-based HP thin client is reported to have problems where
the NVME disk isn't present after resume from s2idle.

This is because the NVME disk wasn't put into D3 at suspend, and
that happened because the StorageD3Enable _DSD was missing in the BIOS.

As AMD's architecture requires that the NVME is in D3 for s2idle, adjust
the criteria for force_storage_d3 to match *all* Zen SoCs when the FADT
advertises low power idle support.

This will ensure that any future products with this BIOS deficiency don't
need to be added to the allow list of overrides.

Merge branches 'acpi-x86', 'acpi-dptf' and 'acpi-apei'

2024-05-13T18:58:14+00:00

Merge x86-specific ACPI updates, an ACPI DPTF driver update adding new
platform support to it, and an ACPI APEI update:

 - Add a num-cs device property to specify the number of chip selects
   for Intel Braswell to the ACPI LPSS (Intel SoC) driver and remove a
   nested CONFIG_PM #ifdef from it (Andy Shevchenko).

 - Move three x86-specific ACPI files to the x86 directory (Andy
   Shevchenko).

 - Mark SMO8810 accel on Dell XPS 15 9550 as always present and add a
   PNP_UART1_SKIP quirk for Lenovo Blade2 tablets (Hans de Goede).

 - Move acpi_blacklisted() declaration to asm/acpi.h (Kuppuswamy
   Sathyanarayanan).

 - Add Lunar Lake support to the ACPI DPTF driver (Sumeet Pawnikar).

 - Mark the einj_driver driver's remove callback as __exit because it
   cannot get unbound via sysfs (Uwe Kleine-König).
