platform/x86: Fix initialization order for firmware_attributes_class

2025-08-01T08:47:28+00:00

[ Upstream commit 2bfe3ae1aa45f8b61cb0dc462114fd0c9636ad32 ] The think-lmi driver uses the firwmare_attributes_class. But this class is registered after think-lmi, causing the "think-lmi" directory in "/sys/class/firmware-attributes" to be missing when the driver is compiled as builtin.

With more files around move everything to a subdirectory. Users will only see the several options once they enable the main one.

platform/x86: simatic-ipc: add CMOS battery monitoring

2023-07-14T13:06:40+00:00

Siemens Simatic Industrial PCs can monitor the voltage of the CMOS battery with two bits that indicate low or empty state. This can be GPIO or PortIO based. Here we model that as a hwmon voltage. The core driver does the PortIO and provides boilerplate for the GPIO versions. Which are split out to model runtime dependencies while allowing fine-grained kernel configuration.

The lenovo-yogabook-wmi.c code now consists of both a platform and a WMI driver and it does not use WMI at all when used on the Android model. Rename the module from lenovo-yogabook-wmi to lenovo-yogabook to reflect this. Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20230430165807.472798-20-hdegoede@redhat.com

platform/x86: Add driver for Yoga Tablet Mode switch

2023-04-06T10:33:34+00:00

This WMI driver for the tablet mode control switch for Lenovo Yoga notebooks was originally written by Gergo Koteles. The mode is mapped to a SW_TABLET_MODE switch capable input device. Andrew followed the suggestions that were posted in reply to Gergo's RFC patch, and on the v1 & v2 versions of this patch to follow-up and get it merged. Changes from Gergo's RFC: - Refactored obtaining a reference to the EC ACPI device needed for the quirk implementation as suggested by Hans de Goede - Applied small fixes and switched to always registering handles with the driver for automatic cleanup as suggested by Barnabás Pőcze. - Merged the lenovo_ymc_trigger_ec function with the ideapad_trigger_ymc_next_read function since it was no longer external. - Added the word "Tablet" to the driver description to hopefully make it more clear. - Fixed the LENOVO_YMC_QUERY_METHOD ID and the name string for the EC APCI device trigged for the quirk - Triggered the input event on probe so that the initial tablet mode state when the driver is loaded is reported to userspace as suggested by Armin Wolf. - Restricted the permissions of the ec_trigger parameter as suggested by Armin Wolf. Also updated the description. We have tested this on the Yoga 7 14AIL7 for the non-quirk path and on the Yoga 7 14ARB7 which has the firmware bug that requires triggering the embedded controller to send the mode change events. This workaround is also used by the Windows drivers. According to reports at https://github.com/lukas-w/yoga-usage-mode, which uses the same WMI devices, the following models should also work: Yoga C940, Ideapad flex 14API, Yoga 9 14IAP7, Yoga 7 14ARB7, etc. Signed-off-by: Gergo Koteles Co-developed-by: Andrew Kallmeyer Signed-off-by: Andrew Kallmeyer Link: https://lore.kernel.org/r/20221004214332.35934-1-soyer@irl.hu/ Link: https://lore.kernel.org/r/20230310041726.217447-1-kallmeyeras@gmail.com/ Link: https://lore.kernel.org/r/20230323025200.5462-1-kallmeyeras@gmail.com/ Tested-by: André Apitzsch Link: https://lore.kernel.org/r/20230329014559.44494-3-kallmeyeras@gmail.com Reviewed-by: Hans de Goede Signed-off-by: Hans de Goede

platform/x86: Add new msi-ec driver

Add a new driver to allow various MSI laptops' functionalities to be controlled from userspace. This includes such features as power profiles (aka shift modes), fan speed, charge thresholds, LEDs, etc. This driver contains EC memory configurations for different firmware versions and exports battery charge thresholds to userspace (note, that start and end thresholds control the same EC parameter and are always 10% apart).

platform/x86: x86-android-tablets: Add support for the Dolby button on Peaq C1010

2023-03-07T11:08:31+00:00

The Peaq C1010 tablet has a special "Dolby" button. This button has a WMI interface, but this is broken in several ways: 1. It only supports polling 2. The value read on polling goes from 0 -> 1 for one poll on both edges of the button, with no way to tell which edge causes the poll to return 1. 3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID). There currently is a WMI driver for this, but it uses several kludges to work around these issues and is not entirely reliable due to 2. Replace the unreliable WMI driver by using the x86-android-tablets code to instantiate a gpio_keys device for this.
