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 v5:
       - do not enable mu2 node by default
       - fix dt_bindings errors

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.

Daniel Baluta (5):
  arm64: dts: imx8mp: Use resets property
  arm64: dts: imx8mp: Add mu2 root clock
  arm64: dts: imx8mp: Configure dsp node for rproc usage
