Hi maintainers, This series introduces the device trees for Ciri, a MT8188-based Chromebook, commercially known as the Lenovo Chromebook Duet (11", 9). Ciri is a detachable device based on the ChromeOS Geralt reference design, where Geralt is the codename for the MT8188 platform. Ciri has 8 SKUs to accommodate the combinations of second-source components, including audio codecs, speaker amplifiers, and MIPI-DSI panels. The Geralt design is not used in any actual products, so its device tree is not included. The device trees are taken from the ChromeOS downstream v6.1 kernel, ported to the mainline kernel and with cleanups. This series aims to provide a basic device tree with the enabled components and features. Additional support will be added in the future after validation with the mainline kernel. This series has been tested on top of the next-20241018 branch. Patch 1 adds entries for Ciri in the MediaTek DT binding. Patch 2 adds the dtsi files for Geralt and Ciri, followed by 8 dts files for all the available Ciri SKUs at this moment. Note that there are some known dtbs_check warnings, depending on binding fix or driver support: - sound: Unevaluated 'xxx-dai-link' properties: sent patch[1] - amplifier '#sound-dai-cells' and other errors: sent patch[1] - dp-tx '#sound-dai-cells' error: sent patch[2] - failed to match 'himax,hx83102j': depend on HX83102J support[3] [1]: https://lore.kernel.org/all/20241025104548.1220076-1-fshao@xxxxxxxxxxxx/ [2]: https://lore.kernel.org/all/20241025104310.1210946-1-fshao@xxxxxxxxxxxx/ [3]: https://lore.kernel.org/all/TY0PR06MB561105A3386E9D76F429110D9E0F2@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/ Regards, Fei Fei Shao (2): dt-bindings: arm: mediatek: Add MT8188 Lenovo Chromebook Duet (11", 9) arm64: dts: mediatek: Introduce MT8188 Geralt platform based Ciri .../devicetree/bindings/arm/mediatek.yaml | 13 + arch/arm64/boot/dts/mediatek/Makefile | 8 + .../dts/mediatek/mt8188-geralt-ciri-sku0.dts | 11 + .../dts/mediatek/mt8188-geralt-ciri-sku1.dts | 63 + .../dts/mediatek/mt8188-geralt-ciri-sku2.dts | 54 + .../dts/mediatek/mt8188-geralt-ciri-sku3.dts | 20 + .../dts/mediatek/mt8188-geralt-ciri-sku4.dts | 43 + .../dts/mediatek/mt8188-geralt-ciri-sku5.dts | 76 + .../dts/mediatek/mt8188-geralt-ciri-sku6.dts | 67 + .../dts/mediatek/mt8188-geralt-ciri-sku7.dts | 52 + .../boot/dts/mediatek/mt8188-geralt-ciri.dtsi | 413 +++++ .../boot/dts/mediatek/mt8188-geralt.dtsi | 1497 +++++++++++++++++ 12 files changed, 2317 insertions(+) create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt-ciri-sku0.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt-ciri-sku1.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt-ciri-sku2.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt-ciri-sku3.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt-ciri-sku4.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt-ciri-sku5.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt-ciri-sku6.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt-ciri-sku7.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt-ciri.dtsi create mode 100644 arch/arm64/boot/dts/mediatek/mt8188-geralt.dtsi -- 2.47.0.163.g1226f6d8fa-goog
