The Surface Pro 11 (Intel/Lunar Lake) Type Cover touchpad (045E:0C8D) needs three fixes: 1. Force clickpad mode: The firmware reports Pad Type = 1 (PRESSUREPAD) and exposes 3 HID buttons, so hid-multitouch's clickpad detection fails. Add MT_QUIRK_FORCE_BUTTONPAD to force INPUT_PROP_BUTTONPAD. 2. Enable firmware palm rejection: The touchpad firmware detects palms and reports Confidence=0 per-contact, but MT_QUIRK_CONFIDENCE was only enabled for a whitelist of Win8 classes. Add the Surface Type Cover 11 class to the whitelist so the kernel reports MT_TOOL_PALM to libinput. 3. Expose whole-pad force sensor: The HID descriptor includes a 16-bit force measurement field (Usage Page 0x20 Sensor, Usage 0x0494) that was being discarded. Map it to ABS_PRESSURE, guarded by MT_QUIRK_FORCE_BUTTONPAD so only the Surface class is affected.
Add the lid GPE (0x2E) used by the Surface Pro 11 with Intel Lunar Lake processor. The GPE was identified from the DSDT _L2E handler which reads the lid GPIO pad (0x0018108E) and sends Notify(LID0, 0x80).
Enable speakers and microphone on the Microsoft Surface Pro 11 Business (Intel Lunar Lake) via SoundWire: - Add Lunar Lake SoundWire link tables and DMI gate (surface_lnl_rt1320_check) for the SP11 RT1320 amplifier + DMIC configuration. - Teach soc_sdw_rt_dmic to bind the RT1320 part IDs so the RT1320 DMIC shows up in the HiFi profile (linux-surface issue #1876). - Force "Playback-/Capture-SmartAmp" stream names for SDW amplifier dailinks so the topology binding matches the sof-lnl-rt1320-l0.tplg expectations.
On the Microsoft Surface Pro 11 Business (Intel Lunar Lake), the EFI ResetSystem call with EFI_RESET_SHUTDOWN fails to power off the system when PCI shutdown callbacks have run for certain devices. Instead of shutting down, the call returns and the system stays on, draining the battery completely overnight. This is the same class of firmware bug seen on the Surface Pro 9 and Surface Laptop 5 (Alder Lake), where Thunderbolt and GPU driver shutdown sequences leave the EFI firmware in a state that prevents power off. Add the Surface Pro 11 to the no_shutdown DMI table (matched via SKU, since the product name is just "Surface Pro" and overlaps with other SKUs), and register PCI fixups for the five Lunar Lake devices that trigger the bug: 8086:a831 Thunderbolt 4 USB Controller 8086:a833 Thunderbolt 4 NHI 8086:a84e Thunderbolt 4 PCI Express Root Port #0 8086:a84f Thunderbolt 4 PCI Express Root Port linux-surface#1 8086:64a0 GPU (Intel Arc Graphics 130V/140V)
Add support for cameras on the Microsoft Surface Pro 11 Business (Intel Lunar Lake / IPU7): - New Sony IMX681 front camera driver (3844x2640, RAW10, 2-lane CSI-2). Register sequences reverse-engineered from Windows I2C traces and other IMX sensors. Uses H-flip (reg 0x0101=0x01) to convert native RGGB Bayer to GRBG matching the Windows AIQB calibration data. - OV13858 rear camera: add get_selection pad op for crop / native size reporting (required by the IPU7 userspace stack). The v6.17-era clock-frequency probe-defer workaround is dropped because v6.18's devm_v4l2_sensor_clk_get() helper now handles deferral internally. - ipu-bridge: register IMX681 (SONY0681) at 969.6 MHz link frequency so IPU7 MIPI CSI-2 enumeration sees the SP11 front sensor. - ipu7: declare MODULE_FIRMWARE entries for the three IPU firmware blobs (ipu7, ipu7p5, ipu8) so initrd builders pick them up.
Add support for the STMicroelectronics VD55G0 global shutter IR sensor used in the Surface Pro 11 (Intel Lunar Lake) for Windows Hello face authentication. The driver is based on the official STMicroelectronics out-of-tree driver (https://github.com/STMicroelectronics/vd55g0-linux-driver) with the following adaptations for kernel integration and Surface Pro 11 support: - Added ACPI device ID table for SMO55F0 and acpi_match_table to the i2c_driver, enabling automatic binding on ACPI-enumerated devices. - Changed fwnode endpoint lookup from of_fwnode_handle() to dev_fwnode() with ACPI fallback: when no fwnode graph endpoint is found on ACPI systems, defaults to 1-lane MIPI at 600 Mbps data rate. - ipu-bridge: register SMO55F0 so the IPU7 MIPI CSI-2 framework can find the IR sensor. - int3472/common.c: recognise VD55G0 as a sensor device. - int3472/discrete.c: add a "0x10" GPIO power-rail type so the SP11's secondary power rail is registered as a regulator.

As requested in linux-surface/linux-surface#1990 a separate PR for the kernel changes. These changes enable audio, camera, suspend/hibernate support on the surface pro for business 11th edition with intel.
Please refer to linux-surface/linux-surface#1990 for the contrib packages that perform additional setup outside the kernel for audio and camera specifically.
Tested with a clean ubuntu 26.04 install. But additional testing is welcome by other users.
