TSENS IP v2.3 onwards adds support for a watchdog to detect if the TSENS HW FSM is stuck. Add support to detect and restart the FSM in the driver. The watchdog is configured by the bootloader, we just enable the watchdog bark as a debug feature in the kernel. Signed-off-by:

TSENS IP v2.x adds critical threshold interrupt support for each sensor in addition to the upper/lower threshold interrupt. Add support in the driver. While the critical interrupts themselves aren't currently used by Linux, the HW line is also used by the TSENS watchdog. So this patch acts as infrastructure to enable watchdog functionality for the TSENS IP. Signed-off-by:

We don't currently call put_device in case of successfully initialising the device. So we hold the reference and keep the device pinned forever. Allow control to fall through so we can use same code for success and error paths to put_device. As a part of this fixup, change devm_ioremap_resource to act on the same device pointer as that used to allocate regmap memory. That ensures that we are free to release op->dev after examining its resources. Signed-off-by:

struct tsens_features is currently initialized as part of platform data at compile-time and not modifiable. We now have some usecases in feature detection across IP versions where it is more flexible to update the features after probing registers. Remove const qualifier from tsens_features and the encapsulating tsens_plat_data. Signed-off-by:

The thermal subsystem may have relied on sysfs in 2008 when it was introduced, but these days the thermal zones will more often than not come from the hardware descriptions and not from sysfs. Drop the "Generic" phrases as well: there are no non-generic drivers that I know of, the thermal framework is by definition generic. Reword a bit and fix some grammar.

The desired behavior of the driver is to generate an interrupt and call thermal_zone_device_update() as soon as the temperature have changed more then one degree. When the set_trips operation was implemented it was believed that the trip window set by the framework would move around the current temperature and the hysteresis value described in devicetree. The behavior of the framework is however to set a window based on the trip points described in devicetree. Remove the set_trips operation which was not used correctly and update the temperatures that triggers interrupts directly from the interrupt handler. Signed-off-by:

Pull irq fixes from Thomas Gleixner: "Two fixes for the irq core code which are follow ups to the recent MSI fixes: - The WARN_ON which was put into the MSI setaffinity callback for paranoia reasons actually triggered via a callchain which escaped when all the possible ways to reach that code were analyzed. The proc/irq/$N/*affinity interfaces have a quirk which came in when ALPHA moved to the generic interface: In case that the written affinity mask does not contain any online CPU it calls into ALPHAs magic auto affinity setting code. A few years later this mechanism was also made available to x86 for no good reasons and in a way which circumvents all sanity checks for interrupts which cannot have their affinity set from process context on X86 due to the way the X86 interrupt delivery works. It would be possible to make this work properly, but there is no point in doing so. If the interrupt is not yet started then the affinity setting has no effect and if it is started already then it is already assigned to an online CPU so there is no point to randomly move it to some other CPU. Just return EINVAL as the code has done before that change forever. - The new MSI quirk bit in the irq domain flags turned out to be already occupied, which escaped the author and the reviewers because the already in use bits were 0,6,2,3,4,5 listed in that order. That bit 6 was simply overlooked because the ordering was straight forward linear otherwise. So the new bit ended up being a duplicate. Fix it up by switching the oddball 6 to the obvious 1" * tag 'irq-urgent-2020-02-22' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: genirq/irqdomain: Make sure all irq domain flags are distinct genirq/proc: Reject invalid affinity masks (again) -
