Pull x86 platform drivers fixes from Ilpo Järvinen: "Mostly a few lines fixed here and there except amd/isp4 which improves swnodes relationships but that is a new driver not in any stable kernels yet. The think-lmi driver changes also look relatively large but there are just many fixes to it. The i2c/piix4 change is a effectively a revert of the commit 7e173eb82ae9 ("i2c: piix4: Make CONFIG_I2C_PIIX4 dependent on CONFIG_X86") but that required moving the header out from arch/x86 under include/linux/platform_data/ Summary: - amd/isp4: Improve swnode graph (new driver exception) - asus-nb-wmi: Use duo keyboard quirk for Zenbook Duo UX8406CA - dell-lis3lv02d: Add Latitude 5500 accelerometer address - dell-wmi-sysman: Fix WMI data block retrieval and class dev unreg - hp-bioscfg: Fix class device unregistration - i2c: piix4: Re-enable on non-x86 + move FCH header under platform_data/ - intel/hid: Wildcat Lake support - mellanox: - mlxbf-pmc: Fix duplicate event ID - mlxbf-tmfifo: Fix vring_desc.len assignment - mlxreg-lc: Fix bit-not-set logic check - nvsw-sn2201: Fix bus number in error message & spelling errors - portwell-ec: Move watchdog device under correct platform hierarchy - think-lmi: Error handling fixes (sysfs, kset, kobject, class dev unreg) - thinkpad_acpi: Handle HKEY 0x1402 event (2025 Thinkpads) - wmi: Fix WMI event enablement" * tag 'platform-drivers-x86-v6.16-3' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86: (22 commits) platform/x86: think-lmi: Fix sysfs group cleanup platform/x86: think-lmi: Fix kobject cleanup platform/x86: think-lmi: Create ksets consecutively platform/mellanox: mlxreg-lc: Fix logic error in power state check i2c: Re-enable piix4 driver on non-x86 Move FCH header to a location accessible by all archs platform/x86/intel/hid: Add Wildcat Lake support platform/x86: dell-wmi-sysman: Fix class device unregistration platform/x86: think-lmi: Fix class device unregistration platform/x86: hp-bioscfg: Fix class device unregistration platform/x86: Update swnode graph for amd isp4 platform/x86: dell-wmi-sysman: Fix WMI data block retrieval in sysfs callbacks platform/x86: wmi: Update documentation of WCxx/WExx ACPI methods platform/x86: wmi: Fix WMI event enablement platform/mellanox: nvsw-sn2201: Fix bus number in adapter error message platform/mellanox: Fix spelling and comment clarity in Mellanox drivers platform/mellanox: mlxbf-pmc: Fix duplicate event ID for CACHE_DATA1 platform/x86: thinkpad_acpi: handle HKEY 0x1402 event platform/x86: asus-nb-wmi: add DMI quirk for ASUS Zenbook Duo UX8406CA platform/x86: dell-lis3lv02d: Add Latitude 5500 ...

platform/x86: Update swnode graph for amd isp4

2025-06-30T09:02:10+00:00

Existing swnode graph format is specific to sensor device and is causing conflicts when accessing standard property variables outside the sensor driver. 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). ACPI device driver_data handle is also initialized with root camera swnode to access the property variables in the graph in isp and i2c drivers.

platform/x86: Use i2c adapter name to fix build errors

2025-06-25T21:39:22+00:00

Use adapater->name inplace of adapter->owner->name to fix build issues when CONFIG_MODULES is not defined.

platform/x86: Add AMD ISP platform config for OV05C10

2025-05-15T11:50:35+00:00

ISP device specific configuration is not available in ACPI. Add swnode graph to configure the missing device properties for the OV05C10 camera device supported on amdisp platform. Add support to create i2c-client dynamically when amdisp i2c adapter is available.
