This set of patches enable mutliple peripherals like USB, PCIe etc.
Additionally, it enables CPUfreq and thermal tripping points.
Please refer to [1] for initial review comments on the PCIe related DT
changes.

Changes in v7:
- In 'Add nodes for multiple peripherals' patch (it has R-B Konrad)
* Reduce critical temperature by about five degrees per recent
calibration updates
* Fix placement of 'efuse@a4000' node
- Move 'spi-{rx,tx}-bus-width = 4' to rdp504-common.dtsi instead of
rdp504-nand.dts
- Change 'reg' details in spi@1a80000 from 32 to 64 bit
- Add #address-cells = <1>; and #size-cells = <0>; to spi0 & spi1 nodes
- Fix incorrect placement of rng@4c3000 node
- Link to v6: https://lore.kernel.org/r/20261008-08-dts-v6-0-f9c4ec8664d8@oss.qualcomm.com
Changes in v6:
- Didn't touch the existing patch as it has R-b
- Add DT changes to enable more devices. Not sure if these can be squashed
into a single patch. Please let me know, will squash if that is
preferrable. Following were added
Random number generator
SPI node definitions
I2C definitions
PWM block
Download mode support
ICE support for sdhci
C3 CPU idle state
Support for WPS button
- New compatibles used are documented in
https://lore.kernel.org/linux-arm-msm/20261008-rng-v1-1-785580a8b48f@oss.qualcomm.com/
https://lore.kernel.org/linux-arm-msm/20261008-pwm-v1-1-0b8776398632@oss.qualcomm.com/
- Link to v5: https://lore.kernel.org/r/20260907-08-dts-v5-0-584e5ab50b40@oss.qualcomm.com
Changes in v5:
- Pick one R-b Konrad
- Do not remove ipq5210-rdp504.dtb from arch/arm64/boot/dts/qcom/Makefile
and add it in a subsequent patch. Instead, move the ipq5210-rdp504.dts
nodes to ipq5210-rdp504.dtb-common.dtsi and include common dtsi in rdp504
dts file and introduce rdp504-nand dts in the 3rd patch
- No code changes
- Link to v4: https://lore.kernel.org/r/20260724-08-dts-v4-0-65e61a1061f0@oss.qualcomm.com
Changes in v4:
- Fix following sashiko comments
- Add #include <dt-bindings/thermal/thermal.h> to dtsi file for
THERMAL_NO_LIMIT definition
- Change tsens interrupt from edge to level
- Remove ipq5210-rdp504.dtb from Makefile in the second patch to
avoid build break and add it back in the 3rd patch
- Dependency related sashiko comments ignored as they are addressed in the
prerequisite patch information
- Link to v3: https://lore.kernel.org/r/20260723-08-dts-v3-0-074eb131f382@oss.qualcomm.com
Changes in v3:
- Address v2 comments
- Introduce RDP504 common dtsi and two board specific dts files one
for NAND and one for eMMC
- Move 'dr_mode' to board file instead of SoC file
- Dropped 'polling-delay-passive = 0' and 'polling-delay = 0'
- Use THERMAL_NO_LIMIT in 'cooling-device'
- '\n' before status = okay
- Removed 'num-lanes' from pcie0 & pcie1 nodes
- Link to v2: https://lore.kernel.org/r/20260715-08-dts-v2-0-b060b68e0256@oss.qualcomm.com
Changes in v2:
- Change usb3@8a00000 -> usb@8a00000
- Ignore other comments as they are covered in the following prerequisite
