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.
