Add a device tree for the HP OmniBook X 16-cp1 laptop, based on the
Qualcomm Mahua (Snapdragon X2 Elite, 12 cores) SoC.
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.
