[PATCH v2 0/6] Configure imx8mp dsp node for rproc usage

[Daniel Baluta]

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.
