Pull ARM devicetree updates from Arnd Bergmann:
 "These are the devicetree updates for Arm and RISC-V based SoCs, mainly
  from Qualcomm, NXP/Freescale, Aspeed, TI, Rockchips, Samsung, ST and
  Starfive.

  Only a few new SoC got added:

   - TI AM62P5, a variant of the existing Sitara AM62x family

   - Intel Agilex5, an FPGFA platform that includes an Cortex-A76/A55
     SoC.

   - Qualcomm ipq5018 is used in wireless access points

   - Qualcomm SM4450 (Snapdragon 4 Gen 2) is a new low-end mobile phone
     platform.

  In total, 29 machines get added, which is low because of the summer
  break. These cover SoCs from Aspeed, Broadcom, NXP, Samsung, ST,
  Allwinner, Amlogic, Intel, Qualcomm, Rockchip, TI and T-Head. Most of
  these are development and reference boards.

  Despite not adding a lot of new machines, there are over 700 patches
  in total, most of which are cleanups and minor fixes"

+description: The SOCTHERM IP block contains thermal sensors, support for
+  polled or interrupt-based thermal monitoring, CPU and GPU throttling based
+  on temperature trip points, and handling external overcurrent notifications.
+  It is also used to manage emergency shutdown in an overheating situation.

+        the thermal framework to implement software shutdown.
+
+      - the "hot" type trip points will be set to SOCTHERM hardware as the
+        throttle temperature.  Once the temperature of this thermal zone is
+        higher than it, it will trigger the HW throttle event.
