Supported and tested: - Keyboard, touchpad and touchscreen over I2C HID - Lid switch - NVMe SSD (PCIe 5) - Qualcomm QCC2072 Wi-Fi (PCIe 4, M.2 key E slot) - Two USB-C ports with orientation switching, USB PD and battery reporting through pmic-glink - USB-A port (usb_2) - Webcam on the internal USB 2.0 host - eDP OLED panel with DP AUX backlight - DisplayPort alt mode on both USB-C ports - ADSP and CDSP remoteprocs - Two speakers (WSA8845) and two digital microphones The GPU is left disabled until Mahua's Adreno X2-85 is supported. This device tree was written with the help of an AI coding assistant (Claude), starting from glymur-hp-elitebook-x-g2q.dts and the laptop's ACPI tables. The regulator voltages were checked against the power votes in the ACPI tables, where they are listed. I reviewed it and tested every feature listed above on the laptop.
