[PATCH v2 0/2] Add binding and driver for Nord SoCCP

[Anurag Pateriya]

This series adds System on Chip Control Processor (SOCCP) remoteproc
support for the Nord platform. SOCCP is a dedicated control processor
that handles hardware fencing for display and other use cases on
Nord-based devices, sharing interrupts, SMP2P states, power domains,
and clock with Kaanapali SoCCP. However, its firmware ships without
a separate SoCCP devicetree image. It therefore takes a single
firmware-name and memory-region, and cannot use the Kaanapali
compatible as fallback.

[PATCH v2 1/2] dt-bindings: remoteproc: qcom,kaanapali-soccp-pas: Add Nord SoCCP

[Anurag Pateriya]

The SoCCP (SoC Control Processor) on Nord handles hardware fencing for
display and other use cases. It shares interrupts, SMP2P states, power
domains, and clock with Kaanapali SoCCP, except that it ships firmware
without a separate devicetree image, so it cannot use the Kaanapali
compatible as fallback.

Add qcom,nord-soccp-pas as a standalone compatible with a single
firmware-name/memory-region pair, while existing SoCs keep requiring two.

[PATCH v2 2/2] remoteproc: qcom_q6v5_pas: Add remoteproc support for SOCCP on Nord

[Anurag Pateriya]

The SoC Control Processor (SoCCP) is a dedicated control processor
that handles hardware fencing for display and other use cases on
Nord based devices. For Nord, SoCCP firmware ships without a
separate SoCCP devicetree image. Therefore, it takes a single
firmware-name and memory-region.
Add support for SoCCP PAS loader on Nord platform.
