[PATCH 0/2] remoteproc: qcom: pas: Add support for CDSP on Eliza SoC

[Abel Vesa]

First, document the compatible and add the DSM memory region
and the NSP power domain, both needed on Eliza.

Then, add the driver data and tie it to the compatible.

[PATCH 1/2] dt-bindings: remoteproc: qcom,milos-pas: Add Eliza CDSP compatible

[Abel Vesa]

Document compatible string for the CDSP Peripheral Authentication
Service on the Eliza SoC. It needs a third memory region (DSM) and
the NSP power domain. Rework the schema to accommodate these.

Re: [PATCH 1/2] dt-bindings: remoteproc: qcom,milos-pas: Add Eliza CDSP compatible

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Medium] Legacy compatible strings silently allow 3 `memory-region` items because they lack an explicit `maxItems: 2` constraint.

[Severity: Medium]
Since adding the third item to the memory-region properties implicitly
raises the maximum limit to 3 globally, should maxItems: 2 be explicitly
specified here for qcom,eliza-adsp-pas and the other legacy devices?

Without an explicit constraint, won't dt_binding_check silently allow
misconfigured device trees for these older devices to incorrectly specify
3 memory regions?

[PATCH 2/2] remoteproc: qcom: pas: Add Eliza CDSP support

[Abel Vesa]

Add dedicated driver data for the Eliza CDSP remote processor. It looks
almost the same as for Milos, except Eliza needs region assign.
Tie the new driver data to the Eliza specific compatible.
