HDMI refers to ThinkPad T14s. Bluetooth refers to x1-crd.dtsi from the ubuntu-concept kernel [1]. PWM brightness control refers to Ratizux's GitHub repository [2]. Tested on linux-next / Ubuntu 26.04 LTS. Tested and working devices: - NVMe - Keyboard & Touchpad - USB Type-A, Type-C - Battery & charging status (broken under EL2 mode) - Internal display & Backlight brightness control - HDMI & Type-C display - Bluetooth & Wi-Fi - Webcam (usb_2) - GPU [1] https://git.launchpad.net/~ubuntu-concept/ubuntu/+source/linux/+git/resolute [2] https://github.com/Ratizux/linux-device-acer-sfa14-11.git --- Changelog: V4: - Add -el2-dtbs. (Sashiko) - The "audio-routing" of "sound" is from x1-crd.dtsi, audio doesn't totally work, and I didn't see any improvements when I followed Sashiko's advice, so I just kept it the same as x1-crd.dtsi. (Sashiko) - Tested in EL2 mode: Successfully boots with the kernel parameter: "iommu.passthrough=1", The above features work as in EL1 mode except battery status. - Fix missing newline before "wsa-dai-link". (Val Packett) V3: - Re-sort *-link and its sub-nodes. (Konrad Dybcio) - Keep a '\n' before 'status'. (Konrad Dybcio) - Remove 'output-low' from wcd_default. (Konrad Dybcio) V2: - Fix Makefile entry ordering. (Krzysztof Kozlowski) - Use readable compatible string. (Krzysztof Kozlowski) - Fix sound card model name for this device. (Krzysztof Kozlowski & Konrad Dybcio) - Re-sort nodes, pinctrl-*. (Krzysztof Kozlowski & Konrad Dybcio) - Remove those regulators without consumer and lack of a required value in DSDT. (Konrad Dybcio) - Remove ADSP/CDSP fastrpc memory. (Konrad Dybcio) - Add iris firmware path. (Konrad Dybcio) - Delete usb_1_ss1_qmpphy/usb_1_ss2_qmpphy properties of Type-C. (Sashiko) - Delete usb_1_ss2_hsphy. (Sashiko) - Remove unused pmic-glink orientation-gpio. (Sashiko) - Remove node related to WWAN. - The Webcam is a USB device, can be probed without any additional node. (Sashiko) - Using reset-gpios in swr* seems common in X1E devices, like Lenovo Yoga Slim7x, ThinkPad t14s and Microsoft Romulus. Because speakers do not completely work and I could not see any effect of changing it, just retain it. (Sashiko) - Also, the HDMI audio is the same reason as above.
