[PATCH v5 0/5] Configure imx8mp dsp node for rproc usage

[PATCH v5 0/5] 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.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.

[PATCH v5 3/5] arm64: dts: imx8mp: Configure dsp node for rproc usage

[Daniel Baluta]

DSP can be used with various frameworks (e.g audio firmware, rproc).
Currently 'dsp' configuration is intended for audio firmware but it
doesn't work well with board level DTs (e.g imx8mp-evk) because
board level DT enables audio related IPs (e.g SAI) while audio firmware
needs this IPs disabled (because firmware will configure them).

So, configure 'dsp' node to be used with rproc. This way users will be
able to use board DT to use the DSP as long as they don't clash with
Audio IP configurations.

More comples usage of 'dsp' node (e.g by audio firmware) will need to
create a separate dts file (or an overlay).

This change follows the approach taken for other i.MX8 boards
in commit 391a319c81f6d7 ("arm64: dts: imx8-ss-audio: configure dsp node
for rproc usage")

[PATCH v5 5/5] arm64: dts: Add dsp rproc related mem regions

[Daniel Baluta]

With imx8mp-evk board we are now configuring 'dsp' node for rproc usage,
so add rproc specific memory regions.

Also, enable dsp node because it is ready to be used.

There is no need to enable MU2 if the DSP is disabled by default, no?

My bot found new DTB warnings on the .dts files added or changed in this
series.

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
