Add initial support for SoCCP on Qualcomm Kaanapali platform. SoC Control
Processor (SoCCP) is loaded by bootloader on Kaanapali. PAS loader will
check the state of the subsystem, and set the status "attached". As the
interrupts are redefined differently for Kaanapali SoCCP, list for the
interrupt properties are moved out of pas-common.

When we return fail in the rproc attach op, current remoteproc core cannot
handle it correctly for further recovery/firmware loading, which should be
generic problem shared across all remoteproc drivers that do attach and
not mandatory for normal bring up, a separate series is used for resolving
this:

- add constraint for smem-states in each file
- "wake-ack" interrupt and "wakeup"/"sleep" smem state have been deprecated in design, drop these

- code clean up for late attach feature
- call rproc_report_crash() instead of set RPROC_CRASHED state
- fix q6v5.running and q6v5.handover_issued state handling
- if wait_for_completion_timeout return 0, set RPROC_OFFLINE for PAS loader

Items in qcom,adsp.yaml has common clock and interrupt properties, move
these out of the allOf section to avoid list the compatible repeatly.

Move interrupts and interrupt-names list out of pas-common since they
will be redefined differently for Kaanapali SoCCP.

Document the component used to boot SoCCP on Kaanapali SoC and add
compatible for Glymur SoCCP which could fallback to Kaanapali. Extend
the "qcom,smem-states", "qcom,smem-state-names" in the pas-common
and add maxItems constraints for SMEM properties in the documents
that reference to pas-common.

+description:
+  The SoC Control Processor (SoCCP) is a small RISC-V MCU that controls USB
+  Type-C, battery charging and various other functions on Qualcomm SoCs, somewhat
+  analogous to traditional PC Embedded Controllers. This document describes
+  the Peripheral Authentication Service that loads and boots firmware for SoCCP.

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] The `IPCC_MPROC_SOCCP` macro in the device tree example is defined without a value, resulting in missing cells after preprocessor expansion.

dt-bindings: remoteproc: qcom: Document pas for SoCCP on Kaanapali and Glymur platforms

Document the component used to boot SoCCP on Kaanapali SoC and add
compatible for Glymur SoCCP which could fallback to Kaanapali. Extend
the "qcom,smem-states", "qcom,smem-state-names" in the pas-common
and add maxItems constraints for SMEM properties in the documents
that reference to pas-common.

Does this macro need a dummy integer value assigned to it, such as
#define IPCC_MPROC_SOCCP 19?

Since it is defined without a value, the C preprocessor will replace it
with an empty string when expanding the cells below.

Because IPCC_MPROC_SOCCP is replaced with an empty string, will this
result in a missing cell for the client ID?

This would cause the properties to expand with a missing cell. A real device
tree using this structure might fail dtc compilation with a cell size
mismatch warning, as the ipcc hardware requires 3 interrupt cells and 2
mailbox cells. The generated DTB might also be functionally incorrect since
the required client ID is omitted.

Just a heads-up for Bjorn, this will have a conflict with Rob's phandle-array
change[1] on linux-next.

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.

Hi Rob,

Will fix in next version.

FYI, seems this err cannot be found on the latest 2026.4 schema, need to update
to the latest 2026.5.dev9+gdf9ad30c5 dev branch and reproduce this.

Thanks,
Jingyi

Subsystems can be brought out of reset by entities such as bootloaders.
As the irq enablement could be later than subsystem bring up, the state
of subsystem should be checked by reading SMP2P bits.

A new qcom_pas_attach() function is introduced. if a crash state is
detected for the subsystem, rproc_report_crash() is called. If the ready
state is detected, it will be marked as "attached", otherwise it could
be the early boot feature is not supported by other entities. In this
case, the state will be marked as RPROC_OFFLINE so that the PAS driver
can load the firmware and start the remoteproc.

Thank you for your contribution! Sashiko AI review found 3 potential issue(s) to consider:
- [Critical] Calling `rproc_report_crash()` followed by returning an error from `.attach()` causes critical Use-After-Free vulnerabilities.
- [High] Returning `-EINVAL` when the subsystem is not ready breaks the intended fallback to offline boot and causes device probe failure.
- [Medium] The `handover_irq` is left enabled on multiple error paths, causing an unbalanced IRQ enablement depth.

remoteproc: qcom: pas: Add late attach support for subsystems

This commit adds late attach support for subsystems brought out of reset by
early bootloaders. It introduces qcom_pas_attach() to check subsystem state
via SMP2P bits, reporting crashes or falling back to offline mode.

If ret is non-zero, we jump to disable_running and return an error without
calling disable_irq(). Does this leave the handover_irq enabled?

Since the attach fails, the remoteproc core never calls the stop callback,
meaning qcom_q6v5_unprepare() is bypassed. This might permanently leak the
IRQ enable count.

Could calling rproc_report_crash() and then returning an error lead to
use-after-free conditions?

rproc_report_crash() asynchronously queues the crash_handler work on
rproc_recovery_wq. If auto_boot is true, the attach failure causes
rproc_add() to abort, and devres will free the rproc object. The queued
crash handler is not explicitly cancelled during cleanup, so it may
dereference the freed rproc memory when it executes.

If auto_boot is false, rproc isn't freed, but rproc_attach() cleans up its
failure by calling rproc_disable_iommu(), which frees rproc->domain. The
async crash handler later executes, fails to abort on the RPROC_DETACHED
state, sets the state to RPROC_CRASHED, and triggers recovery. The recovery
process calls rproc_stop() -> qcom_pas_stop() -> qcom_pas_unmap_carveout(),
which unconditionally dereferences the freed rproc->domain via
iommu_unmap().

Additionally, does this path leave the handover_irq enabled as well?

Does returning -EINVAL here prevent the intended fallback to offline boot?

If the device has auto_boot enabled, rproc_add() treats the -EINVAL from
the auto-boot attempt as a fatal error. It executes goto rproc_remove_dev,
which destroys the remoteproc device entirely and fails the driver probe.
This makes the intended fallback impossible, as the device is never
registered.

I am not sure if this is already discussed, but what if it is the first
crash with recovery and coredump enabled? What would be in the dump,
nothing? As there is no segment, is it expected since Linux did not load
this?

This is even true if it is a crash after a successful attach.

@Sibi, has this series been tested on Glymur with KVM?
I don't see the iommu property in the below patch.

Good point, Mukesh!

I guess we can have a check in qcom_pas_minidump() to do nothing 
in case state is RPROC_ATTACHED?

The SoC Control Processor (SoCCP) is small RISC-V MCU that controls
USB Type-C, battery charging and various other functions on Qualcomm SoCs.
It provides a solution for control-plane processing, reducing per-subsystem
microcontroller reinvention. Add support for SoCCP PAS loader on Kaanapali
platform.
