[PATCH v5 0/7] Add initial device trees for Nord platform

[Shawn Guo <shengchao.guo@oss.qualcomm.com>]

This series adds initial device tree support for Qualcomm's Nord SoC
and the reference design boards, SA8797P RIDE for Automotive and IQ10 RRD
for Robotics.

Nord includes two variants, GearVM and Embedded. The GearVM variant has
platform resources (clocks, regulators, powerdomains, etc.) controlled
by SCMI server running on a VM. And the Embedded variant has the resources
directly controlled by Linux.

SA8797P RIDE board is built on GearVM variant, while IQ10 RRD is built
on Embedded variant.

Tested on next-20260706.

Binding Dependencies:
- ICE: https://lore.kernel.org/all/20260704004408.2303468-1-shengchao.guo@oss.qualcomm.com/
- I2C: https://lore.kernel.org/all/20260707095708.3801043-1-shengchao.guo@oss.qualcomm.com/

Changes for v5:
- Rename nord-sa8797p.dtsi to nord-gearvm.dtsi
- Merge scmi-common.dtsi to nord-gearvm.dtsi
- Drop "qcom,sa8797p" compatible
- Add Nord Embedded variant and IQ10 RRD board support
- Link to v4: https://lore.kernel.org/all/20260707123902.3868016-1-shengchao.guo@oss.qualcomm.com/

Changes for v4:
- Rebase on next-20260706
- 1/4: Drop useless comments from arm,gic-v3 reg property
- 1/4: One triple per line for qcom,pdc-ranges
- 2/4: Improve commit log as suggested by Konrad
- 4/4: Drop 0 polling-delay as that's the default value
- 4/4: Name PMIC thermal zones with prefix "pmic" rather than "pm"
- 4/4: Drop 135 C trip point from PMIC thermal zones as hardware will shutdown
  at 125 C
- 4/4: Have trip0 at 105 C as passive and trip1 at 115 C as critical for UFS
  and SDRAM thermal zones
- Link to v3: https://lore.kernel.org/all/20260526051300.1669201-1-shengchao.guo@oss.qualcomm.com/

Changes for v3:
- Rebase on next-20260525 and drop patches/dependencies that hit linux-next
- Improve commit log of "Document SA8797P Ride board" to explain the need
  of SA8797P model compatible
- Fix the real issues reported by sashiko-bot
  - Fix unit address of pdp0_a2p node
  - Add missing compatible for i2c15 and spi15
  - Drop GIC_CPU_MASK_SIMPLE(8) from arch_timer interrupts property
  - Update commit log of "Add device tree for Nord SA8797P SoC" to match
    code change
  - Sort sa8797p-ride thermal trips in ascending order of temperature
  - Fix sa8797p-ride thermal zones with identical trip0 and trip1
- Link to v2: https://lore.kernel.org/all/20260519063505.883379-1-shengchao.guo@oss.qualcomm.com/

Changes for v2:
- Rebase on next-20260518 and drop dependencies that hit linux-next
- Include SoC ID changes into the series
- Include ICE binding change into the series as the prerequisite change
  from Harshal [1] was merged to qcom soc tree instead of crypto
- Improve commit log of SA8797P Ride binding change
- Use label in nord-sa8797p.dtsi for referencing nodes defined in
  the base nord.dtsi
- Link to v1: https://lore.kernel.org/all/20260427023455.236410-1-shengchao.guo@oss.qualcomm.com/
