Subject: [PATCH 0/6] iio: adc: versal-sysmon: Add OT alarm, shutdown and thermal zone support
Date: Mon, 2 Nov 2026 17:51:06 +0530 [thread overview]
Message-ID: <20261102122112.1723130-1-amit.kumar-mahapatra@amd.com> (raw)
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
