[PATCH RFC v3 0/3] arm64: dts: qcom: nord: Enable SoCCP remoteproc support

[Anurag Pateriya]

This series adds device tree support for SoCCP
(System on Chip Control Processor) on Nord platform.
SoCCP is used for hw fencing for display and other
use cases on Nord.

It has the same interrupts, SMP2P states, power domains
and clock as Kaanapali SoCCP, but its firmware ships without a separate
SoCCP devicetree image. It therefore takes a single firmware-name and
memory-region.

Prerequisite series:

[PATCH v5 0/7] arm64: dts: qcom: nord: Add remoteproc and PMIC support

https://lore.kernel.org/all/20261014063953.549379-1-shengchao.guo@oss.qualcomm.com/

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

https://lore.kernel.org/all/20261014-soccp_driver_dtbinding-v2-0-09d9c1378e9e@oss.qualcomm.com/

Changes in v3:
- Rearranged remoteproc_soccp node in nord-rrd.dts alphabetically after remoteproc_cdsp3 node. (Shawn)
- Replaced nord-soccp-pas compatible from nord.dtsi to nord-embedded.dtsi to resolve binding check issues in nord-ride.dtb.(Shawn)
- Link to v2: https://lore.kernel.org/r/20261018-nord-soccp-dt-v2-0-4d713d316e9d@oss.qualcomm.com

Changes in v2:
- Drop the BWMON nodes from the Nord SoC as they are outside the scope of this series. (Konrad, Abel)
- Enable SoCCP by default on Nord and drop the board-level status overrides. (Konrad)
- Amend the RRD and Ride-Embedded board commits to describe the addition of SoCCP support rather than its enablement.
- Fix missing whitespace before the opening brace in the RRD SoCCP node. (Konrad)
- Got Reviewed-By tags from Abel.
- Link to v1: https://lore.kernel.org/r/20261016-nord-soccp-dt-v1-0-ee13aef55d8b@oss.qualcomm.com

[PATCH RFC v3 1/3] arm64: dts: qcom: nord: Add SoCCP remoteproc DT support for Nord

[Anurag Pateriya]

Add the SoCCP (System on Chip Control Processor) remoteproc node and
its SMP2P configuration at the SoC level in nord.dtsi, and wire up
the clock and power-domain dependencies shared by all Nord embedded
variants in nord-embedded.dtsi.

Move the SoCCP compatible to nord-embedded.dtsi to fix binding
errors reported for the Ride board.
