[PATCH v2 0/3] arm64: dts: qcom: Introduce Asus Zenbook A14 (UX3407NA)

[Bjorn Andersson]

UX3407NA is a variant of the Asus Zenbook A14 built on the Qualcomm
Glymur platform.

This (v2) remains dependent on the eDP support here:
https://lore.kernel.org/linux-arm-msm/20260622-glymur-edp-phy-v1-0-814b45089ac9@oss.qualcomm.com/

As reported by both Chris and Nicko, the A14 only has 2 speakers so this
has now been resolved. But, on linux-next I need to introduce a
pm_runtime_forbid() in the soundwire controller (swr0) to avoid SWR bus
clashes when trying to play audio.

UCM config and audioreach topologies can be found here:
  https://github.com/alsa-project/alsa-ucm-conf/pull/858
  https://github.com/linux-msm/audioreach-topology/pull/78

The power grid was revised since v1 which removes the crosstalk
previously seen between eDP and WiFi TX - which means WiFi is now
functional (with the right board-2.bin).

HDMI remains non-functional, patches for this are being prepared.

---
Changes in v2:
- Dropped chosen {}
- Protected EC reset pin
- Added camera, mic and privacy LEDs
- Changed WiFi/BT to use the M.2 binding
- Added a bit of CMA for good measure
- Corrected speaker descriptions (there seems to only be 2 WSAs)
- Added missing redriver definitions
- Rebased on pcie3 PHY changes
- Added tcsr supplies
- Patches prepared and posted on the Zenbook A14 itself
- Link to v1: https://patch.msgid.link/20260623-zenbook-dts-v1-0-3f80f680381d@oss.qualcomm.com

[PATCH v2 1/3] dt-bindings: arm: qcom: Add Asus Zenbook A14 (UX3407NA)

[Bjorn Andersson]

UX3407NA is a variant of the Asus Zenbook A14 built on the Qualcomm
Glymur platform. It comes with an 18-core X2 Elite SoC, 32GB DDR, NVMe
storage, a WUXGA OLED screen, and the other typical Glymur platform
capabilities.

Add a compatible for this machine.

[PATCH v2 2/3] arm64: dts: qcom: glymur: Add Asus Zenbook A14 (UX3407NA)

[Bjorn Andersson]

UX3407NA is a variant of the Asus Zenbook A14 built on the Qualcomm
Glymur platform. It comes with an 18-core X2 Elite SoC, 32GB DDR, and
the other typical Glymur platform capabilities.

The Asus Zenbook uses &pcie3b for NVMe storage, the screen is WUXGA
OLED, it has two USB Type-C ports, one USB Type-A, and one HDMI port.

[PATCH v2 3/3] firmware: qcom: scm: Allow QSEECOM on Asus Zenbook A14 (UX3407NA)

[Bjorn Andersson]

In line with other Glymur-based machines, the Asus Zenbook A14
(UX3407NA) exposes EFI variables through the "uefisecapp". Add it to the
QSEECOM allowlist to enable this access.

arm64: dts: qcom: glymur: Add Asus Zenbook A14 (UX3407NA)

This commit adds device tree support for the Asus Zenbook A14 (UX3407NA)
variant built on the Qualcomm Glymur platform. It introduces the base
hardware description, including the X2 Elite SoC, storage, display,
and USB connectivity.

[Severity: Medium]
The commit message explicitly states the device has "one USB Type-A" and
makes no mention of an SD card reader. Does this hardware actually have a
second redriver, or is ptn3222_1 a leftover from another model's configuration?

If this hardware does not exist on the board, the kernel will attempt to probe
a non-existent I2C redriver which can cause boot probe errors.

[Severity: Medium]
The second Multi-Port PHY is fully enabled here, which directly contradicts

Could enabling this second PHY waste power and cause initialization errors by
attempting to bring up non-existent hardware on the boot path?
