This work is based on the initial work of Merck Hung . The Windows Dev Kit 2023 is a nice little desktop based on sc8280xp. Link: https://learn.microsoft.com/en-us/windows/arm/dev-kit/ Supported features: - USB type-c and type-a ports - minidp connector - built-in r8152 Ethernet adapter - PCIe devices - nvme - ath11k WiFi (WCN6855) - WCN6855 Bluetooth - A690 GPU - Venus codec - ADSP and CDSP - GPIO keys - Audio definition (works via USB) Signed-off-by: Jens Glathe Signed-off-by: Merck Hung Original work: https://github.com/merckhung/linux_ms_dev_kit/blob/ms-dev-kit-2023-v6.3.0/arch/arm64/boot/dts/qcom/sc8280xp-microsoft-dev-kit-2023.dts This dt is more or less deducted from the Thinkpad X13s. It contains a lot of guesswork, and also a lot of research on what works with the Windows Dev Kit. The WiFi definition references qcom,ath11k-calibration-variant = "volterra" which is unfortunately not yet in the linux-firmware. You can leave it out, and the ath11k driver finds the default one for "bus=pci,vendor=17cb,device=1103,subsystem-vendor=17cb,subsystem-device=0108,qmi-chip-id=2|18,qmi-board-id=255" which is quite sub-optimal. I have placed a pr on github/qca-swiss-army-knife: https://github.com/qca/qca-swiss-army-knife/pull/9 that provides an amended board-2.bin and a board-2.json to generate it. pcie2 (nvme) is intentionally specified as max-link-speed = <16>. The interface is capable of it, most current nvme ssds are capable of it, but the physical slot isn't. This leads to a silent downgrade to <8> instead of the "device is limited by bus, capable of..." message. It is in use and under development since May 2023, pretty stable now. --- Changes in v4: - removed the redundant regulator definitions - changed the pinctrl property order - use microsoft instead of MICROSOFT as subdirectory and device name component - amend spacing in audio nodes - change external connector dp1 for mini-dp to DP-3 for consistency - Link to v3: https://lore.kernel.org/r/20241013-jg-blackrock-for-upstream-v3-0-839d3483a8e7@oldschoolsolutions.biz Changes in v3: - tried to heed all advice and comments given - thank you - re-ordered patches to definition before use - added "microsoft,blackrock" as compatible in QSEECOM driver - removed the qseecom node - ordered nodes alphabetically {address, node name, label} - amended indentation - consistently used blackrock as identifier / directory name - sorted identifiers by the same order for multiple instances - added some explanation re WiFi - added definition for PMU on the WCN6855 - added some explanation for pcie2 max-link-speed - Link to v2: https://lore.kernel.org/r/20240920-jg-blackrock-for-upstream-v2-0-9bf2f1b2191c@oldschoolsolutions.biz Changes in v2: - removed whitespaces and breaks - added compatibility binding - added feature list - reformatted Signed-off list - Link to v1: https://lore.kernel.org/r/5f5487e1-e458-4a3a-af02-c52e50ca1964@oldschoolsolutions.biz --- Jens Glathe (3): dt-bindings: arm: qcom: Add Microsoft Windows Dev Kit 2023 firmware: qcom: scm: Allow QSEECOM for Windows Dev Kit 2023 arm64: dts: qcom: sc8280xp-blackrock: dt definition for WDK2023 Documentation/devicetree/bindings/arm/qcom.yaml | 1 + arch/arm64/boot/dts/qcom/Makefile | 1 + .../boot/dts/qcom/sc8280xp-microsoft-blackrock.dts | 1383 ++++++++++++++++++++ drivers/firmware/qcom/qcom_scm.c | 1 + 4 files changed, 1386 insertions(+) --- base-commit: a39230ecf6b3057f5897bc4744a790070cfbe7a8 change-id: 20240920-jg-blackrock-for-upstream-7c7aca20e832 Best regards,
