Add board support for the HP EliteBook X G2q 14" Next Gen AI PC
(product SKU C4JG0AV, board 8E91), a Snapdragon X2 Elite (Glymur)
laptop, using the "hp,elitebook-x-g2q" / "qcom,glymur" compatible.
Enabled by this device tree:
- internal eDP panel (samsung,atna33xc20)
- 2x USB Type-C with DisplayPort alt-mode and USB
- chassis HDMI output
- chassis USB-A host port (usb_mp multiport controller)
- internal eUSB2 host with the Elan fingerprint reader
- NVMe SSD on PCIe5
- Wi-Fi and Bluetooth
- HID-over-I2C keyboard, touchpad, touchscreen; lid switch
- Adreno GPU and GMU (Freedreno GL on Mesa)
- audio playback and capture
- real-time clock
- compute DSP (cDSP)
The HDMI jack is driven by a power-only DisplayPort-to-HDMI LSPCON on
the usb_2 combo-PHY DP lanes rather than being a third USB-C port; HPD
is on gpio126. The LSPCON is on an I/O sub-board with no I2C/AUX control
path, so it is modelled with the generic simple-bridge "parade,ps185hdm"
compatible used by the in-tree x1e80100 HDMI-bridge boards (the exact
bridge part is unconfirmed) and it needs CONFIG_DRM_SIMPLE_BRIDGE.
The &gpu/&gmu enable, the audio nodes and &remoteproc_soccp opt into
glymur.dtsi SoC nodes that are still in-flight; those series are
declared as prerequisites in the cover letter.

The HP EliteBook X G2q 14" Next Gen AI PC is a Snapdragon X2 Elite
(Glymur) laptop whose firmware exposes EFI variables through QSEECOM.
Add its board compatible to the QSEECOM allowlist so that EFI variable
access (efivarfs) works on this machine.
Without it the kernel reports "qseecom: untested machine, skipping" and
efivarfs is empty.
