Patch 1 adds the board compatible under qcom,mahua and follows the Gen 6 T14s pattern with distinct -lcd / -oled variants. Patch 2 is the T14s Gen 7 (LCD) device tree itself; it follows the Qualcomm Glymur reference design used by mahua-crd. Patch 3 adds the board to the QSEECOM allowlist, matching the pattern used for the Yoga Slim 7x Gen 11, HP EliteBook X G2q 14 AI and Zenbook A14. Currently working on the board: internal eDP display, WSA8845 speaker playback and DMIC capture, DisplayPort audio on the two USB-C DP outputs (DP0/DP1), USB-C (host + charging on both ports), WCN7850 Wi-Fi and Bluetooth, NVMe, HID-over-I2C touchpad / keyboard / TrackPoint, lid switch, internal USB2 camera on usb_hs (via PTN3222 redriver) and Goodix fingerprint reader on usb_2. WWAN wiring is included but untested (no such SKU on hand). Changes since v2 [1]: - Drop the panel-edp patch; the CSOT MNE007QB1-1 entry has landed - Enable internal USB2 camera on usb_hs (via PTN3222 redriver) - Enable Goodix fingerprint reader on usb_2 - Picked up Reviewed-by: Konrad Dybcio on the DTS - Re-add the QSEECOM allowlist patch that was sent as 4/4 in v1 [2] and inadvertently dropped from v2 [1] https://lore.kernel.org/all/20260918120515.595782-1-srinivas.kandagatla@oss.qualcomm.com/ [2] https://lore.kernel.org/all/20260913201835.250085-1-srinivas.kandagatla@oss.qualcomm.com/ Srinivas Kandagatla (3): dt-bindings: arm: qcom: add Lenovo ThinkPad T14s Gen 7 (Mahua) arm64: dts: qcom: Add Lenovo ThinkPad T14s Gen 7 firmware: qcom: scm: Allow QSEECOM on ThinkPad T14s Gen 7 .../devicetree/bindings/arm/qcom.yaml | 7 + arch/arm64/boot/dts/qcom/Makefile | 1 + .../mahua-lenovo-thinkpad-t14s-gen7-lcd.dts | 1272 +++++++++++++++++ drivers/firmware/qcom/qcom_scm.c | 1 + 4 files changed, 1281 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/mahua-lenovo-thinkpad-t14s-gen7-lcd.dts base-commit: 6375e61c01e93e35ee7acd336a689ac1fae4b509 -- 2.53.0
