  firmware: arm_ffa: Correct 32-bit response handling in NOTIFICATION_INFO_GET (2025-12-18 14:22:07 +0000)

----------------------------------------------------------------
Arm FF-A updates for v7.0

A small set of updates to the Arm FF-A driver:

1. Fix a correctness issue in NOTIFICATION_INFO_GET handling of 32-bit
   firmware responses, avoiding reads from undefined register bits.

2. Improve clarity and robustness of FF-A feature checks by tying them
   to explicit version requirements.

3. Ensure Rx/Tx buffers are unmapped on FF-A initialization failure to
   prevent resource leaks.

  arm64: dts: arm: Use hyphen in node names (2026-01-01 17:31:07 +0000)

----------------------------------------------------------------
Armv8 Juno/Vexpress updates for v7.0

This contains a small set of DT updates:

1. Align DTS node naming with established coding style by replacing underscores
   with hyphens in node names. This is a safe change and does not affect ABI.

2. Add support for the CMN PMU on the Arm Morello platform, exposing the
   CMN-Skeena (CMN-600 r3p1–compatible) PMU via the standard CMN-600 binding.
   This enables PMU access on real Morello SDP hardware, where the registers
   are functional.

  firmware: arm_scmi: Remove legacy protocol versioning logic (2025-12-27 20:09:30 +0000)

----------------------------------------------------------------
Arm SCMI updates for v7.0

A set of cleanups, refactoring, and fixes to the Arm SCMI stack:

1. Rework protocol version negotiation by moving version discovery and
   downgrade handling into the SCMI core and performing negotiation early,
   before protocol initialization. Remove legacy per-protocol versioning
   logic now made redundant by centralized SCMI handling.

2. Increase the internal MAX_OPPS limit in the SCMI performance protocol
   to 64, allowing platforms with larger OPP tables to be fully supported.

3. Reduce duplicated boilerplate in pinctrl and related protocols by
   consolidating validation and lookup logic in protocol get info helpers.

4. Refactor reset protocol domain handling by introducing a shared lookup
   helper, ensuring consistent validation and error reporting.

5. Fix potential undefined behaviour by properly initializing pointers
   annotated with the __free attribute.

It seems pw-bot did not TY this one, so to confirm - I merged this, thanks.

Best regards,
