Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments. If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date: pip3 install dtschema --upgrade New warnings running 'make CHECK_DTBS=y qcom/sm7125-xiaomi-joyeuse-touch.dtb' for 20241015-nt36xxx-v1-0-3919d0bffee6@gmail.com: arch/arm64/boot/dts/qcom/sm7125-xiaomi-joyeuse-touch.dts:9:10: fatal error: sm7125-xiaomi-joyeuse-display.dts: No such file or directory 9 | #include "sm7125-xiaomi-joyeuse-display.dts" | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. make[3]: *** [scripts/Makefile.dtbs:131: arch/arm64/boot/dts/qcom/sm7125-xiaomi-joyeuse-touch.dtb] Error 1 make[2]: *** [scripts/Makefile.build:478: arch/arm64/boot/dts/qcom] Error 2 make[2]: Target 'arch/arm64/boot/dts/qcom/sm7125-xiaomi-joyeuse-touch.dtb' not remade because of errors. make[1]: *** [/home/rob/proj/linux-dt-testing/Makefile:1412: qcom/sm7125-xiaomi-joyeuse-touch.dtb] Error 2 make: *** [Makefile:224: __sub-make] Error 2 make: Target 'qcom/sm7125-xiaomi-joyeuse-touch.dtb' not remade because of errors.
Initially support for nt36xxx series spi device. Below list all supported varients: - NT36675 - NT36672A - NT36772(?) - NT36525 - NT36676F I had tested it with Redmi note 9 pro, aka NT36675 chip. This series is based on my repo below: https://github.com/99degree/linux/tree/nt36xxx There is a boot-and-functional tree for miatoll device: https://github.com/99degree/linux/tree/working-20241015 And the older dev history: https://github.com/99degree/linux/tree/nt36xxx_old https://github.com/99degree/linux/tree/working-20230528/drivers/input/touchscreen This driver is based on AngeloGioacchino Del Regno for i2c based drive https://patchwork.kernel.org/project/linux-input/cover/20201028221302.66583-1-kholk11@gmail.com/#24831734 _AND_ Neil Armstrong for the spi device codes https://patchwork.kernel.org/project/linux-input/patch/20231213-topic-goodix-berlin-upstream-initial-v13-2-5d7a26a5eaa2@linaro.org/ Download fw function is adapted from original vendor driver https://github.com/LineageOS/android_kernel_xiaomi_sm6250/tree/lineage-21/drivers/input/touchscreen/nt36xxx_spi/ Panel follower functionality is finally added. Since the driver is split into core+spi so i2c function is relatively easily to add.
