[PATCH v2 0/3] X2 Elite HP EliteBook X G2q support

[PATCH v2 0/3] X2 Elite HP EliteBook X G2q support

[Jason Pettit]

This series adds initial device-tree support for the HP EliteBook X G2q
14" Next Gen AI PC (product SKU C4JG0AV, board 8E91), a Snapdragon X2
Elite (Glymur) laptop.

The board was brought up and validated on real hardware. The electrical
description (PMIC rails, PHY supplies, the HDMI bridge wiring) was
verified against the live unit rather than copied from a Glymur CRD.

Working on this laptop with this series applied:

  - Internal eDP panel (samsung,atna33xc20)
  - 2x USB Type-C with DisplayPort alt-mode and USB
  - Chassis HDMI output
  - Chassis USB-A host port
  - Fingerprint reader
  - NVMe SSD on PCIe5
  - Wi-Fi, Bluetooth
  - Keyboard, touchpad, touchscreen, lid switch
  - Adreno GPU and GMU (Freedreno GL on Mesa)
  - Audio playback and capture
  - Real-time clock
  - Compute DSP (cDSP)

This patch series builds upon the recent work of Qualcomm engineers to
enable another Glymur-based laptop.

Like its peer submissions, the camera support is missing today.

This has the same known dependencies as other boards on this
platform (audio, GPU, SoCCP series).

The GPU device-tree patches come from the partially merged Glymur GPU DT
v5 series at
https://lore.kernel.org/all/20260522-glymur-gpu-dt-v5-0-562c406b210c@oss.qualcomm.com/

SCMI on this configuration needs CONFIG_QCOM_CPUCP_MBOX built in (=y).

The bindings patch is independent and can be reviewed/applied on its own.
The board patch can be reviewed in parallel with the GPU, LPASS and SoCCP
SoC series. Until those land in the target tree, it will trip the expected
"Label or path ... not found" dtc error. As with the X2 Elite Lenovo Yoga
Slim 7x submission, this v1 is expected to trigger some dt-bindings warnings
that come from the in-flight dependency series, not from the board patch
itself.

Changes in v2:
- Enable the PMIC RTC (qcom,no-alarm + qcom,uefi-rtc-info)
- Add the SMB2370 eUSB2 repeaters on usb_0/usb_1
- Enable the compute DSP (remoteproc_cdsp / fastrpc)
- Addressed comments from reviewers on v1
- Link to v1: https://lore.kernel.org/linux-arm-msm/20260620-glymur-send-v1-0-fc4a2cfd107c@oss.qualcomm.com

[PATCH v2 2/3] arm64: dts: qcom: Add HP EliteBook X G2q 14 AI

[Jason Pettit]

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.

[PATCH v2 3/3] firmware: qcom: scm: Allow QSEECOM on HP EliteBook X G2q 14 AI

[Jason Pettit]

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.

Re: [PATCH v2 2/3] arm64: dts: qcom: Add HP EliteBook X G2q 14 AI

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] The `usb_2` DWC3 controller and its high-speed PHY are explicitly enabled despite having no physical connection and being completely unused.

commit cd918ca13e11bd1a5f9fec450e22054021db1490
Author: Jason Pettit <jason.pettit@oss.qualcomm.com>

arm64: dts: qcom: Add HP EliteBook X G2q 14 AI

Add board support for the HP EliteBook X G2q 14" Next Gen AI PC.
This enables various device tree nodes including the HDMI output,
eUSB2, NVMe, and other peripherals on the Snapdragon X2 Elite platform.

[Severity: Medium]
Since this port is used purely for DisplayPort-to-HDMI output via the
combo-PHY DP lanes, and the eUSB2 repeater is explicitly noted as never
probing, should the usb_2 DWC3 controller and usb_2_hsphy be enabled here?

Leaving status = "okay" for the unused DWC3 controller and its high-speed PHY
binds drivers that will consume resources like memory and IRQs unnecessarily
for hardware that isn't connected.

I would assume it's simply not present (as every SMB2370 is a separate
physical chip) - perhaps we should just add status = "disabled" in the
DTSI file and enable the nodes on an as-needed basis

If you remove these two nodes, the QMPPHY-as-DP-only should still
function (it's the USB3 block that depends on the QMPPHY, not the
other way around)
