Subject: [PATCH 0/4] arm64: dts: qcom: Add Lenovo ThinkPad T14s Gen 7
Date: Sun, 13 Sep 2026 21:18:31 +0100 [thread overview]
Message-ID: <20260913201835.250085-1-srinivas.kandagatla@oss.qualcomm.com> (raw)
Add device tree support for the Lenovo ThinkPad T14s Gen 7 [1], a Mahua
(Snapdragon X2 Elite) laptop, together with the drm/panel-edp entry
for its internal panel and a QSEECOM allowlist entry.
Tested on the platform:
- Display (internal eDP and external DP on both USB-C ports)
- USB-C data + charging on both ports
- Wi-Fi (WCN7850) and Bluetooth
- NVMe on PCIe5
- HID-I2C touchpad, keyboard, TrackPoint, lid switch
- Audio playback (2x WSA8845 speakers) and capture (DMICs)
- ADSP / CDSP / SoCCP
Not tested / out of scope:
- WWAN (wiring included but no SKU with the modem to test)
- GPU / GMU (kept out of scope for this bring-up)
my working tree is: https://github.com/Srinivas-Kandagatla/linux/tree/upstream/t14s-Gen7
alsa ucm is in : https://github.com/Srinivas-Kandagatla/alsa-ucm-conf/tree/t14s-gen7
I plan to enable DP audio and other things in parallel.
--srini
Depends on Bjorn's:
- phy: qcom: edp: split power-on sequencing by PHY version
- phy: qcom: edp: update v8 power-on programming sequence
