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 for

DSP found in i.MX8MP SOC can be used by multiple frameworks in order to enable various applications: - rproc/rpmsg framework, used to load for example Zephyr samples - Sound Open Firmware, used to enable various audio processing pipelines. Current dsp node was configured with SOF in mind but it doesn't work well with imx8mp-evk dts. SOF controls audio IPs from firmware side while imx8mp-evk.dts preffers to control audio IPs from Linux side. So, configure 'dsp' node to be used with rproc scenario and later will add a separate dts or an overlay to configure the node for SOF. This patch series configures and enables dsp node to be used with rproc. Changes since v4: (https://lore.kernel.org/linux-arm-kernel/Z6zGLn3B6SVXhTV1@lizhi-Precision-Tower-5810/T/) - after comments received on v4, we implemented the run/stall bits using reset controller API (changes merged -> https://patchwork.kernel.org/project/linux-arm-kernel/cover/20250311085812.1296243-1-daniel.baluta@nxp.com/) - drop patches related to DSP run/stall/reset via syscon - picked up patch related to using run_stall via reset controller API.
