[PATCH 5/5] arm64: dts: qcom: Add Microsoft Surface Laptop 8th Edition
From: Gopikrishna Garmidi
Date: Tue Oct 06 2026 - 05:52:55 EST
Add support for the Microsoft Surface Laptop 13.8" 8th Edition, which is
built on the Mahua SoC. Most of the board follows the Qualcomm reference
design. The keyboard, fan and platform profile sit behind the Surface
Aggregator Module on uart22, same as on the Surface Laptop 7.
What works:
- internal eDP panel (link capped at HBR, HBR2 fails channel equalization)
- both USB-C ports, host and charging
- USB multiport controller behind the two PTN3222 eUSB2 redrivers
- Wi-Fi and Bluetooth (WCN7850)
- speakers (2x WSA8845) and the two DMICs
- NVMe
- keyboard, fan and platform profile via SAM
- touchpad and touchscreen (HID over I2C)
- lid switch
The GPU and GMU remain disabled because support is not yet
functional on this platform.
