This patch series:
- Fixes a race between the interrupt teardown and the interrupt handler
- Validates the temperature hysteresis written by userspace and read
  from hardware at probe
- Adds a .shutdown callback so the SysMon alarm interrupts are disabled
  when the system shuts down or kexecs into another kernel
- Adds the over-temperature (OT) alarm as an event-only channel labelled
  "ot", alongside the existing device temperature event
- Updates the Versal SysMon maintainers: removes Salih Erim, who is no
  longer with AMD, and adds myself
- Describes the SysMon in the Versal NET device tree, with a thermal
  zone on its device temperature
- Adds thermal zone support for the SysMon using the existing
  generic-adc-thermal driver
