[ Upstream commit 6418a8504187dc7f5b6f9d0649c03e362cb0664b ] When KCOV is enabled all functions get instrumented, unless the __no_sanitize_coverage attribute is used. To prepare for __no_sanitize_coverage being applied to __init functions[1], we have to handle differences in how GCC's inline optimizations get resolved. For thinkpad_acpi routines, this means forcing two functions to be inline with __always_inline.

On some models supported by ideapad-laptop, the HW/FW can remember the state of keyboard backlight among boots. However, it is always turned off while shutting down, as a side effect of the LED class device unregistering sequence.

Fixes a logic issue in mlxreg_lc_completion_notify() where the intention was to check if MLXREG_LC_POWERED flag is not set before powering on the device. The original code used "state & ~MLXREG_LC_POWERED" to check for the absence of the POWERED bit. However this condition evaluates to true even when other bits are set, leading to potentially incorrect behavior. Corrected the logic to explicitly check for the absence of MLXREG_LC_POWERED using !(state & MLXREG_LC_POWERED).

2025-06-30Move FCH header to a location accessible by all archsMario Limonciello1-1/+1
A new header fch.h was created to store registers used by different AMD drivers. This header was included by i2c-piix4 in commit 624b0d5696a8 ("i2c: piix4, x86/platform: Move the SB800 PIIX4 FCH definitions to <asm/amd/fch.h>"). To prevent compile failures on non-x86 archs i2c-piix4 was set to only compile on x86 by commit 7e173eb82ae9717 ("i2c: piix4: Make CONFIG_I2C_PIIX4 dependent on CONFIG_X86").

To address this issue, enhanced swnode graph format with dedicated nodes for i2c and isp devices, with sensor node added as child to i2c node. This approach allows to have standard property variables (ex: 'clock-frequency') with values applicable for each of the devices (sensor, i2c and isp).

It turns out that the Windows WMI-ACPI driver always enables/disables WMI events regardless of whether they are marked as expensive or not. This finding is further reinforced when reading the documentation of the WMI_FUNCTION_CONTROL_CALLBACK callback used by Windows drivers for enabling/disabling WMI devices: The DpWmiFunctionControl routine enables or disables notification of events, and enables or disables data collection for data blocks that the driver registered as expensive to collect. Follow this behavior to fix the WMI event used for reporting hotkey events on the Dell Latitude 5400 and likely many more devices.

2025-06-17platform/x86: portwell-ec: Move watchdog device under correct platform hierarchyIvan Hu1-0/+1
Without explicitly setting a parent for the watchdog device, the device is registered with a NULL parent. This causes device_add() (called internally by devm_watchdog_register_device()) to register the device under /sys/devices/virtual, since no parent is provided. The result is: DEVPATH=/devices/virtual/watchdog/watchdog0 To fix this, assign &pdev->dev as the parent of the watchdog device before calling devm_watchdog_register_device(). This ensures the device is associated with the Portwell EC platform device and placed correctly in sysfs as: DEVPATH=/devices/platform/portwell-ec/watchdog/watchdog0 This aligns the device hierarchy with expectations and avoids misplacement under the virtual class.
