Merge tag 'thermal-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control updates from Rafael Wysocki:
 "These add a thermal library and thermal tools to wrap the netlink
  interface into event-based callbacks, improve overheat condition
  handling during suspend-to-idle on Intel SoCs, add some new hardware
  support, fix bugs and clean up code.

  Specifics:

   - Add thermal library and thermal tools to encapsulate the netlink
     into event based callbacks (Daniel Lezcano, Jiapeng Chong).

   - Improve overheat condition handling during suspend-to-idle in the
     Intel PCH thermal driver (Zhang Rui).

   - Use local ops instead of global ops in devfreq_cooling (Kant Fan).

   - Clean up _OSC handling in int340x (Davidlohr Bueso).

   - Switch hisi_termal from CONFIG_PM_SLEEP guards to pm_sleep_ptr()
     (Hesham Almatary).

   - Add new k3 j72xx bangdap driver and the corresponding bindings
     (Keerthy).

   - Fix missing of_node_put() in the SC iMX driver at probe time
     (Miaoqian Lin).

   - Fix memory leak in __thermal_cooling_device_register()
     when device_register() fails by calling
     thermal_cooling_device_destroy_sysfs() (Yang Yingliang).

   - Add sc8180x and sc8280xp compatible string in the DT bindings and
     lMH support for QCom tsens driver (Bjorn Andersson).

   - Fix OTP Calibration Register values conforming to the documentation
     on RZ/G2L and bindings documentation for RZ/G2UL (Biju Das).

   - Fix type in kerneldoc description for __thermal_bind_params
     (Corentin Labbe).

   - Fix potential NULL dereference in sr_thermal_probe() on Broadcom
     platform (Zheng Yongjun).

   - Add change mode ops to the thermal-of sensor (Manaf Meethalavalappu
     Pallikunhi).

   - Fix non-negative value support by preventing the value to be clamp
     to zero (Stefan Wahren).

   - Add compatible string and DT bindings for MSM8960 tsens driver
     (Dmitry Baryshkov).

   - Add hwmon support for K3 driver (Massimiliano Minella).

   - Refactor and add multiple generations support for QCom ADC driver
     (Jishnu Prakash).

   - Use platform_get_irq_optional() to get the interrupt on RCar driver
     and document Document RZ/V2L bindings (Lad Prabhakar).

   - Remove NULL check after container_of() call from the Intel HFI
     thermal driver (Haowen Bai)"
