[PATCH 0/5] dt-bindings: remoteproc: Document Glymur ADSP/CDSP PAS

[PATCH 0/5] dt-bindings: remoteproc: Document Glymur ADSP/CDSP PAS

[Sibi Sankar]

The series documents the AOSS, IPCC and ADSP/CDSP remoteproc bindings
required to add initial support for ADSP/CDSP remoteprocs on Glymur SoCs.

Dependencies:
Peripheral Image Loader support for Qualcomm SoCs running Linux host at EL2:
https://patchwork.kernel.org/project/linux-arm-msm/cover/20250921-kvm_rproc_pas-v3-0-458f09647920@oss.qualcomm.com/
Patches 4/5 have a dependency on the iommu binding added in ^^ series.

[PATCH 2/5] dt-bindings: mailbox: qcom-ipcc: Document Glymur physical client IDs

[Sibi Sankar]

Document the physical client IDs specific to Glymur SoCs. Physical client
IDs are used on newer Qualcomm platforms including Glymur, since the Inter
Process Communication Controller (IPCC) HW block no longer has the virtual
to physical mapping in place.

^^ patch seems to assume physical IDs are common across SoCs but it doesn't
seem to hold true on Glymur.

Maybe QCom should sort that out before sending us stuff...

This belongs with patch 1 as it is part of the binding/ABI.

That's obvious. Say something useful here like how the h/w compares to 
existing documented h/w. Like perhaps the change from virtual ids to 
physical ids, whatever that means...

The min can never be 0, so it is already 1. Drop.

Hey Rob,

Thanks for taking time to review the series :)

Will add more relevant information during the next re-spin.
