Subject: [PATCH v4 0/6] configure imx8 dsp DT node for rproc usage

From: Laurentiu Mihalcea <laurentiu.mihalcea@....com>

Configure/add imx8 dsp DT node for rproc usage.
Additionally, fix number of power domains from the fsl,dsp.yaml binding.

---
Changes in v4:
- Added Krzysztof's and Frank's R-b's.

- Wrapped DT commit messages to 75 chars.

- Placed 'mbox-names' after 'mboxes' property in 'vpu_dsp' DT node.

- Link to v3: https://lore.kernel.org/lkml/20241011150439.4027-1-laurentiumihalcea111@gmail.com/

Changes in v3:
- Moved handling of IRQSTR_DSP PD to fiwmare side. Now QXP has 2
mandatory PDs, while QM has 4.

- Dropped the optional PDs. All PDs are now mandatory.

- Dropped Linux implementation details from the binding's commit
message.

- Renamed reserved memory nodes to generic "memory".

- Split QXP board and soc DT changes into dif. patches.

- Dropped comments about SOF and rewrote the commit message of the
patch that modifies the 'dsp' node from 'imx8-ss-audio.dtsi'. Hopefully,
should be more clear why the change is done.

- Squashed arm,mhuv2 binding changes.

- Link to v2: https://lore.kernel.org/lkml/20240925232008.205802-1-laurentiumihalcea111@gmail.com/

Changes in v2:
- Modify subject of commit changing fsl,dsp.yaml to state that the change
is for fsl,dsp.yaml

- Fix issue with arm,mhuv2 binding found by Rob's bot caused by the
changes to fsl,dsp binding

- Improve formatting of commit messages

- Link to v1: https://lore.kernel.org/lkml/20240918182117.86221-1-laurentiumihalcea111@gmail.com
