[PATCH v4 0/7] arm64: dts: qcom: nord: Add remoteproc and PMIC support

[Shawn Guo]

This series adds ADSP and CDSP remoteproc support, the SPMI PMIC arbiter
and the PMIC descriptions for the Qualcomm Nord platform, and adds the
initial device tree for the Nord Ride Embedded board.

Tested on next-20260929.

Bjorn,

Due to that RTC maintainer is not very active this development cycle[1],
I'm including the PMM8654AU RTC change in the series to get it route
through qcom tree.

If you consider to merge the series, please pull the commit e484a765f543
("dt-bindings: power: qcom,rpmhpd: Add NMXC power domain index") from
Ulf's branch below to resolve NMXC defines.

Thanks,
Shawn

Changes for v4:
- Update firmware-name for ADSP/CDSP to align with linux-firmware,
  i.e. adsp_dtbs.elf -> adsp_dtb.mbn, cdsp_dtbs.elf -> cdsp_dtb.mbn
- Use the same firmware for all 4 CDSPs to align with linux-firmware
- Drop "Embedded" from model string for nord-ride-embedded.dts
- Include PMM8654AU RTC binding change into the series
- Link to v3: https://lore.kernel.org/all/20260920084920.2201418-1-shengchao.guo@xxxxxxxxxxxxxxxx/

Changes for v3:
- Reword commit log of 5/6 as suggested by Krzysztof
- Add memory-region for ADSP fastrpc node
- Link to v2: https://lore.kernel.org/all/20260904081619.593602-1-shengchao.guo@xxxxxxxxxxxxxxxx/

Changes for v2:
- Align PMIC comments in nord-ride-embedded.dts with nord-rrd.dts
- Drop unneeded regulator-always-on and regulator-boot-on from RPMh
  regulators
- Drop SMPS regulators as the resources are already managed by rpmhpd
- Use pmm8654au compatible with fallback on pmk8350 for pon, pwrkey,
  resin and rtc
- Link to v1: https://lore.kernel.org/all/20260831032103.341633-1-shengchao.guo@xxxxxxxxxxxxxxxx/
