platform/x86: Fix initialization order for firmware_attributes_class

2025-08-01T08:48:40+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.

platform/x86: Add new MeeGoPad ANX7428 Type-C Cross Switch driver

2024-05-15T08:07:11+00:00

Some MeeGoPad top-set boxes have an ANX7428 Type-C Switch for USB3.1 Gen 1 and DisplayPort over Type-C alternate mode support. The ANX7428 has a microcontroller which takes care of the PD negotiation and automatically sets the builtin Crosspoint Switch to send the right signal to the 4 highspeed pairs of the Type-C connector. It also takes care of HPD and AUX channel routing for DP alternate mode. IOW the ANX7428 operates fully autonomous and to the x5-Z8350 SoC things look like there simple is a USB-3 Type-A connector and a separate DisplayPort connector. Except that the BIOS does not power on the ANX7428 at boot (meh). Add a driver to power on the ANX7428. This driver is added under drivers/platform/x86 rather than under drivers/usb/typec for 2 reasons: 1. This driver is specifically written to work with how the ANX7428 is described in the ACPI tables of the MeeGoPad x86 (Cherry Trail) devices. 2. This driver only powers on the ANX7428 and does not do anything wrt its Type-C functionality. It should be possible to tell the controller which data- and/or power-role to negotiate and to swap the role(s) after negotiation but the MeeGoPad top-set boxes always draw their power from a separate power-connector and they only support USB host-mode. So this functionality is unnecessary and due to lack of documentation this is tricky to support.

platform/x86: wmi: Add MSI WMI Platform driver

2024-04-29T10:06:21+00:00

Add a new driver for the MSI WMI Platform interface. The underlying ACPI WMI interface supports many features, but so far only reading of fan speed sensors is implemented. The driver was reverse-engineered based on a user request to the lm-sensors project, see the github issue for details. The ACPI WMI interface used by this driver seems to use the same embedded controller interface as the msi-ec driver, but supports automatic discovery of supported machines without relying on a DMI whitelist. The driver was tested by the user who created the github issue.

platform/x86: Add ACPI quickstart button (PNP0C32) driver

2024-04-08T13:22:22+00:00

This drivers supports the ACPI quickstart button device, which is used to send manufacturer-specific events to userspace. Since the meaning of those events is not standardized, userspace has to use for example hwdb to decode them. The driver itself is based on an earlier proposal, but contains some improvements and uses the device wakeup API instead of a custom sysfs file.
