Niklas Söderlund 7617e771c1 thermal: rcar_thermal: Always update thermal zone on interrupt
Since commit a1ade56538 ("thermal: rcar: check every
rcar_thermal_update_temp() return value") the temperature is always read
in rcar_thermal_get_current_temp() so comparing it before and after
enabling interrupts have little effect. Remove the check and always
update the thermal zone when we get an interrupt that the temperature
have changed.

HW FSM is stuck. Add support to detect and restart the FSM in the

Amit Kucheria 79125e03db drivers: thermal: tsens: Add critical interrupt support
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.

Amit Kucheria f22a3bf0d2 drivers: thermal: tsens: Release device in success path
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.

Niklas Söderlund 267c4d8d13 thermal: rcar_gen3_thermal: Generate interrupt when temperature changes
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.

Linus Torvalds f3cc24942e 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.

Linus Torvalds b98b809c0a SCSI fixes on 20200221
Four non-core fixes.  Two are reverts of target fixes which turned out
 to have unwanted side effects, one is a revert of an RDMA fix with the
 same problem and the final one fixes an incorrect warning about memory
 allocation failures in megaraid_sas (the driver actually reduces the
 allocation size until it succeeds).
