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 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 v1:
- document syscon compatible as pointed by Peng Fan
- do not disable dsp_reserved node in the dtsi file as pointed
by Ahmad Fatoum.
