[PATCH v3 0/3] Add ADSP and CDSP support for Nord SoC

[PATCH v3 0/3] Add ADSP and CDSP support for Nord SoC

[Shawn Guo]

The series documents AOSS side channel, adds ADSP (HPASS DSP) and
4 CDSPs support for Nord SoC.

Nord SoC actually have 3 ADSPs. This series only enables ADSP0 which
can work independently. The rest two instances have dependencies on
ADSP0 regarding start/stop and SSR. And remoteproc framework doesn't
seem to support such "slave" instances yet.

Changes for v3:
- Fix qcom,nord-pas bindings to define "minItems: 3" for CDSPs with
  an else clause
- Link to v2: https://lore.kernel.org/all/20260724103848.233804-1-shengchao.guo@oss.qualcomm.com/

Changes for v2:
- Create a new qcom,nord-pas.yaml to cover Nord ADSP and CDSP
- Include CDSPs support into the series
- Link to v1: https://lore.kernel.org/all/20260709085149.4072181-1-shengchao.guo@oss.qualcomm.com/

[PATCH v3 2/3] dt-bindings: remoteproc: qcom,nord-pas: Document Nord PAS

[Shawn Guo]

Add a dedicated binding for the Qualcomm Nord SoC PAS devices: ADSP
and CDSPs. Nord ADSP uses CX and MX power domains while the CDSPs
add an NSP domain on top of that.

[PATCH v3 3/3] remoteproc: qcom: pas: Add Nord ADSP and CDSP support

[Shawn Guo]

Add support for ADSP (HPASS DSP) and 4 CDSPs found on Nord SoC. The ADSP
is pre-booted by XBL before Linux starts, so set early_boot flag for
attach path rather than a cold boot sequence.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The example defines the macro `IPCC_MPROC_ADSP0` without a value, which results in an empty token replacement and corrupts the cell counts for `interrupts-extended` and `mboxes`.

Author: Shawn Guo <shengchao.guo@oss.qualcomm.com>

dt-bindings: remoteproc: qcom,nord-pas: Document Nord PAS

This commit adds a new device tree binding for the Qualcomm Nord SoC
Peripheral Authentication Service (PAS). It defines the required properties,
power domains, and interrupts for the ADSP and CDSP devices, and provides an
example device tree node.

[Severity: Low]
Does this empty macro definition corrupt the cell counts later in the example?

Because IPCC_MPROC_ADSP0 is defined without a value here, it evaluates to
nothing. This causes both the interrupts-extended and mboxes properties in the
glink-edge node below to silently drop the required client ID cell. The IPCC
mailbox controller expects 3 cells for interrupts and 2 cells for mboxes.

[Severity: Low]
This isn't a bug, but does inserting "nord" before "msm" violate the
alphabetical ordering of the qcom_pas_of_match array? Because "m" comes
before "n" alphabetically, should the "nord" entries be placed after the
"msm" entries to maintain the list's sorted order and prevent merge
conflicts?
